This chapter provides readers with an overview of the public-sector applications of shared mobility data and directs them to information sources where additional detailed information can be found on specific topics of interest. It includes summaries of relevant literature and online documents; sample documents and agreements relating to provision, management, and sharing of shared mobility data; relevant data standards and open-source software related to these standards; organizations that are active in these topic areas; and examples of public datasets and dashboards provided by public agencies across the country.
Shared mobility is “the shared use of a vehicle, motorcycle, scooter, bicycle, or other travel mode; it provides users with short-term access to a travel mode on an as-needed basis” (SAE J3163_201809). Its scope includes micromobility services such as bikesharing and electric scooter services, as well as car sharing, microtransit, paratransit, transportation network companies (TNCs), and traditional ride-hailing (taxi) services.
Shared mobility services have grown rapidly within just a few years. They help solve the last mile problem by providing links to and from mass transit stations and can replace car trips. They also may substitute for walking and transit trips. Some shared services can address longer trips, such as the use of microtransit, where there is insufficient demand for efficient use of fixed route transit, or car-sharing services, for occasional or periodic trips where a car is desirable.
When available, public agencies use the data from these providers for operations, planning and analysis, and enforcement. Operations applications include evaluating performance and deal with subjects such as vehicle utilization, vehicle caps, prohibited zones for operations or parking, and identifying areas that may be under- or overserved. Planning and analysis applications examine how the service fits into the larger transportation ecosystem and include using data to understand demand patterns for shared mobility, what physical infrastructure is being used (e.g., for parking), what routes are being taken (and, hence, where new bicycle infrastructure might be suitable), what the right price for curb space is, and the relationship with transit stations. Enforcement activities involve monitoring and auditing provider operations to ensure that both mobility providers and their customers are complying with established regulations. Specific activities may include determining whether service providers are accurately reflecting the status of their fleets, how well providers are rebalancing and maintaining their fleets, and when and where people are riding scooters in prohibited areas. In addition, there are topics of interest that cut across these application areas. Crosscutting topics include data sharing policies and practices (including privacy protection), the use of third parties for data management and analysis, and topics closely related to shared mobility, such as curb management.
Just as some cities were taken by surprise by TNCs and struggled to put in place regulatory frameworks, many localities have had the same experience with dockless bikes and scooters. There is a clear need for public agencies to have data to better understand how all these services fit into the overall transportation network. However, there is tension between public agencies and service providers over the sharing of data. Shared mobility providers possess proprietary data as well as personally identifiable information (PII) relating to their customers. They understandably wish to protect these data. At the same time, the public sector needs some of the data in sufficient detail and with sufficient timeliness to fulfill its operations, planning, and enforcement functions. This has created tension and a lack of trust. There is a need for model data governance agreements, adequate protection of proprietary and personal data, and a better understanding of needs and issues between the public and private sectors to increase trust.
There is also a variation in the amount of standardization and data sharing across the many shared mobility modes. For example, the General Bikeshare Feed Specification (GBFS) (NABSA n.d.) and the Mobility Data Specification (MDS) (OMF n.d.-d) provide a fairly comprehensive, widely used standard for micromobility data, but no similar standards yet exist for TNCs or other shared mobility services. State and local data-reporting laws are often also very different for micromobility and TNC operators.
The purpose of this chapter is to provide public-sector agencies with a curated guide to resources to help them plan for, manage, and utilize shared mobility data. The guide is intended not to be a comprehensive encyclopedia, but rather to provide an overview on the data management needs related to each topic and provide readers with summaries of resources where more detailed guidance and reference information can be found. The content of each resource is categorized and summarized to enable readers to determine those that best address their specific issues.
The primary intended audience includes management and staff of public agencies responsible for shared mobility, including those that use data for regulating shared mobility operations and those who use this type of data for broader planning purposes, such as implementing bike lanes or integrating shared mobility with transit operations. Both agencies that are taking on the challenge of internally managing shared mobility data and those looking to contract these services out to a third party will find material to assist them.
The organization of this chapter is intended to help readers easily locate the specific sections relevant to their topics of interest. More than 40 resources on data management are summarized in this chapter. Some of the summaries also list additional related resources. The bulk of the resources deal with micromobility; however, many of these have information or recommendations that are equally applicable to other shared mobility services, such as TNCs, ride hailing, and microtransit. The following topic areas are covered:
The next section of the chapter discusses each of the seven topic areas, and the discussion of each topic area is accompanied by a table that lists all the resources for that topic by type of resource. The section on topic areas is followed by the catalog of resources, the primary section of the guide. The resources are organized according to type, as follows:
For each resource, the following information is given: title, author (if applicable), type of resource, where to obtain it, topic areas covered, a short summary of the content, and a more detailed description. In some cases, links to additional closely related resources are also provided.
The references cited are listed at the end of the chapter.
This section provides a summary of each topic and a cross-reference to the resources that contain information on each topic. The two broad topic categories are applications, which are the primary reason the data are needed and why they are analyzed, and crosscutting practices.
Applications can be further divided into operations, planning and analysis, and enforcement.
This application topic deals with the day-to-day operations of shared mobility services, which include monitoring and managing the total number of vehicles in operation and vehicle utilization and identifying under- or overserved areas. Operational questions that an agency might seek to answer include the following:
The data that are needed include
In addition to collecting data from service providers, public agencies also need to provide data to service providers. Especially with regard to dynamic information, there is a benefit to standardizing and automating this information flow, and the MDS is one standard that addresses this need. The types of information that may flow from agencies to service providers include
However, apart from MDS, there is little other material addressing the information flows from public agencies, and most of the references in this guide deal only with information coming from service providers.
Resources for the topic of operations are indexed by type in Table 12-1.
This topic deals with issues that are more long term than daily operations as well as broader topics, such as transportation planning, overall impact on the streets or city, or the impact of micromobility on street design. Following are some questions that public agencies may seek to answer:

Data on usage, demand, and trip-level can be used to determine the location of new bike/scooter lanes and vehicle parking areas and to allocate curb usage, all of which provide value to the service providers as well as the general community. Another area of interest for most localities is the interrelationships and interactions between various shared mobility modes and public transit operations, such as the use of shared mobility to address last mile issues or the extent to which shared mobility services compete with transit for usage and ridership. These types of analyses can help service providers demonstrate the value that they are providing to the community.
Along with other data sources, the specific types of data from mobility providers that might be needed include time-dependent origin–destination data, routes taken, trip duration, number of vehicles by service type and status within specified geographic and time boundaries, number of trips taken per vehicle per day, and parking area usage.
Resources for planning and analysis are indexed by type in Table 12-2.
These types of applications include enforcing both service provider and user compliance with regulations. The two are interrelated, as enforcement policies may hold the service provider

responsible for the actions of its users. These policies may include regulations related to operations in restricted areas, speed violations, parking or riding on sidewalks, and restricted hours of operation.
This topic also includes information needed to calculate any fees due from operators, which may be based on the number of vehicles deployed, the number in use per day, or other criteria.
Another important aspect of enforcement and fee collection is verifying the accuracy of provider data with independently measured ground truth data to identify and resolve discrepancies. This can include using check rides, independent observations, and data auditing tools.
Resources for enforcement are indexed by type in Table 12-3.
Crosscutting practices discussed in this section include the following:
This topic deals with data sharing agreements and policies that public agencies put in place for getting data from shared mobility providers and storing and using that data as well as how private and proprietary data will be protected. In some cases, the requirements are included in operating agreements, permits, or licenses, while in other cases they are separate documents incorporated by reference. They may cover items such as what data must be reported, how frequently, and in what format(s); allowed uses for the data; who owns the data; and requirements for privacy protection.
Most of the material available in this area addresses micromobility services rather than other forms of shared mobility such as TNCs. This came about for a combination of reasons. First, micromobility services came later, and, by that time, cities were better prepared and had a better understanding of what information they needed as well as the legal structures to insist that it be provided. In addition, at the urging of TNCs, several states preempted the ability of local

governments to collect data from TNCs. Despite this, TNCs and traditional ride-hailing (taxi) operators may have similar data sharing requirements. For example, Seattle specifies the data that must be collected by taxicab associations, for-hire vehicle companies, and TNCs. The regulations cover what data must be collected, the data retention requirements (2 years), and the reporting requirements (quarterly) (City of Seattle, WA n.d.). Similarly, the California Public Utilities Commission lays out annual reporting requirements for TNCs (California Public Utilities Commission n.d.) and the New York City Taxi and Limousine Commission (TLC) requires regular reporting by both TNCs and ride-hailing companies (New York City TLC n.d.).
Resources for data sharing policies and practices are indexed by type in Table 12-4.
This topic is closely related to and overlaps with data sharing policies and practices but is distinct enough to warrant being called out into a separate topic. Third parties are hired by the public agency. They have experience working in multiple cities and with multiple service providers, which enables them to often have a better understanding of the issues relating to data than a public agency. These third parties can audit data provided by operators and ensure that consistent definitions are used for reporting. The use of third parties to obtain, store, and analyze shared mobility data is also one method for resolving the tensions between providing information that is adequate for public agencies to perform their functions while ensuring adequate protection of private and proprietary information.
Public agencies have a legitimate need for data to effectively plan their transportation systems, to develop regulations for the best use of shared mobility, and to enforce those regulations. Some of this analysis requires the use of the type of trip-specific information that raises privacy concerns. At the same time, the collection, storage, and use of such data by public agencies raises multiple legitimate concerns. Some agencies, especially smaller ones, may simply lack the specific skills and resources needed to effectively manage and analyze the large volumes of data. In addition, some datasets, such as trip-specific data, raise privacy concerns that require special handling, for which requirements sometimes come into conflict with existing state freedom-of-information laws. This occurs because, although location-specific data are not considered (PII), such data can often be combined with other public data to enable re-identification and, thereby, reveal sensitive information about individual activities. Some existing state laws do not adequately protect such data from Freedom-of-Information Act (FOIA) requests or other types of disclosure. Finally, the mobility providers themselves are rightfully protective of their proprietary data as well as their customers’ privacy and see risks with sharing data with public-sector agencies, since disclosure to competitors could harm their business. Care must be taken even with aggregate data to ensure that they cannot be disaggregated (e.g., if there are only two providers for a given service type).
One approach for dealing with these issues is for an agency to contract with a trusted third party to manage and analyze the data. These third parties receive raw data from mobility providers but do not provide the raw data to government agencies or to any other organizations. They securely store whatever data need to be kept and conduct the analyses that public agencies need to manage mobility providers. The public agencies receive the results of the analyses along with anonymous aggregated data. There are currently nonprofit universities and private for-profit corporations providing these services.

Curb space is a limited resource with increasing demands for use as pick-up and drop-off space for both people and goods, scooter corrals, and other uses. Multiple communities are digitizing the data associated with curb rules as well as fees that some communities are beginning to charge for curb access. The data include the georeferenced rules and regulations applying to various sections of curb in a municipality, as well as to pricing of curb access, whether for parking, pick-up and drop-off, or the delivery of freight.
One example is Los Angeles’ Code the Curb initiative, which was launched in 2016 (LADOT n.d.). Code the Curb provides a digital, geocoded reference for all the city’s traffic signs, painted curbs, and other regulatory tools. Private-sector and nonprofit entities are also working in this area. SharedStreets, for example, has created CurbLR, a proposed standard for describing curb regulations such as those in the Code the Curb initiative (SharedStreets n.d.-a). Safari AI works with public agencies and delivery operators to better manage, coordinate, and schedule curb access (Safari AI 2024). The Open Mobility Foundation has also begun to look at developing a common specification as part of the MDS for digitized curb data and is coordinating with SharedStreets (OMF 2020a), among numerous other public agency and private-sector stakeholders.

The article does not provide specific language for agreements; rather, it provides specific recommendations on what should be considered for inclusion in any agreement as well as what should be avoided. The information is presented on a topic-by-topic basis.
This article is an excellent resource for understanding the importance of data sharing agreements and identifying what public agencies should and should not include when drafting, reviewing, or entering into any sort of data sharing agreement with private-sector mobility providers regarding sharing mobility data.
Additional Details: The recommendations are divided into three major parts, each of which includes several focus areas. The article discusses the various types of licenses and recommends that data sharing agreements be either embedded in permit agreements or incorporated by reference. It also recommends the use of a standard agreement with all providers rather than negotiating different agreements with each provider. Other topics discussed include but are not limited to the following:

Description: Ten-page survey of data sharing policies across multiple U.S. cities.
Summary: The author surveyed the data sharing policies of more than a dozen U.S. cities, including Nashville, TN; Chicago, IL; Santa Monica, CA; San Francisco, CA; Pittsburgh, PA; Austin, TX; and Dallas, TX. Some of these cities had pilot programs, some had postpilot operational programs, and one had an emergency data sharing rule in place.

On the basis of the survey results, the author identified four major findings:
Note that at the time the survey was conducted, the MDS was a newly emerging standard being developed by the Los Angeles Department of Transportation (LADOT). The subsequent widespread adoption of the MDS may change some of the findings.
Additional Details: The report includes a comprehensive table of 12 cities and the types of data collected by each city (trips, fleet, customer survey, parking, maintenance, safety/incidents, and data validation). All 12 cities required trip data, and 11 of the 12 required fleet data. Only two specifically addressed data validation.
For trip and fleet data, the report provides details, walking through an overview of the findings, why the data type is important, and how it is being collected across the surveyed cities. The results for the other data types are covered more briefly. In addition, there is a good discussion on reporting frequency and the use of application programming interfaces (APIs) versus static, periodic reports. Since the report was published, the widespread adoption of the MDS makes the case for APIs even stronger than what is included in the report.

Description: Glossary that “provides a consensus-based set of definitions for terms and metrics that are commonly used. It outlines key vehicle, trip, and geospatial definitions and metrics to reduce discrepancies in the terminology used across jurisdictions and sectors and allow public agencies to clarify policies related to shared micromobility.”
Topic Area(s):
Data Sharing Policies and Practices
Operations
Policy and Analysis
Resource Type:
Literature or Online Resource
Summary: The 19-page glossary focuses on vehicle and trip-level data. It provides standardized, often hierarchical, definitions of terms as well as vehicle-based and trip-based performance metrics and standardized methods for calculating these metrics.
Additional Details: The definitions are short textual descriptions in English. For example, vehicle is “a motorized or human-powered vehicle [that] could include an automobile, motorcycle, (e-)bike, e-scooter, or moped that is used for transportation.” At the highest level, a vehicle may be in “Deployed,” “Removed,” or “Unknown” status. Deployed vehicles may be “Operational” or “Non-Operational.” Operational Vehicles may be “In-Use” or “Available.” Both “Available” and “Non-Operational” vehicles are in the “Idle” state.
To fully define vehicle and trip terms, several geographic terms (e.g., “service area,” “waypoint”) and time-related terms (e.g., “available time,” “operational time”) are also defined.
The glossary then defines many vehicle and two trip-based performance metrics and presents mathematical formulas for how they should be calculated. For example, the average number of vehicles of a specified status in a specified geographic area over a specified time is given as
where
avgveh = average number of vehicles of a specified status,
vehi = number of vehicles of a specified status at i,
i = sampling frequency (e.g., time units in minutes), and
T = time of interest (i.e., total number of i samples).

Summary: This document is a tool for identifying metrics addressing equity, safety, environment, and usage. It defines outcomes, metrics for each outcome, the data required for each metric, and the data source.
Additional Details: The guide covers metrics for a dozen outcomes:
For each outcome, the following is provided: a short definition; one or more questions to answer to assess the outcome measure; and evaluation, policy, and equity metrics that relate to each question. The data required for each specific metric are then identified. For example, one question under access to vehicles is “How far does the average user have to travel to find a vehicle?” A policy metric associated with that question is the “percentage distribution coverage” (total area covered by a quarter-mile radius around each vehicle divided by the total service area). A goal might be “50% coverage 75% of the time.” The data required would be
All but the two spatial files are data that are specified in the MDS. The spatial data are expected to be found in a locality’s open data.

Resource: Urgent Privacy Concerns with City’s Decision to Collect Traveler Mobility Location Information
Author: Center for Democracy and Technology
Date: 2020
Description: Two letters from the Center for Democracy and Technology—one to the District (Washington, DC) Department of Transportation (DDOT) and the other to the LADOT—raising privacy issues and concerns with data provided by using the MDS.
Topic Area(s):
Data Sharing Policies and Practices
Resource Type:
Literature or Online Resource
Summary: The first letter expresses concerns over DDOT’s decision to require trip reporting via MDS and to require the data to be reported in near real time. The letter references the second letter to LADOT, which goes into much more detail, with references, over the privacy concerns raised by the collection of detailed trip-level data and makes specific policy recommendations.
Additional Details: The first letter cites the U.S. Supreme Court’s finding that time-stamped location data “provides an intimate window into a person’s life, revealing not only his particular movements, but through them his ‘familial, political, professional, religious, and sexual associations.’ ” It urges DDOT to use aggregated data to meet its needs for planning data.
The second letter acknowledges LADOT’s recognition that data collected via the MDS should be classified as “confidential” data under the city’s information handling guidelines but calls on LADOT to be more specific as to how the data will be safeguarded, including data retention policies; the uses to which the data will be put; and how access will be controlled. The letter cites specific examples, with references, on how confidential location-specific data can and have been misused and explains why trip data raise serious privacy concerns. The letter then lays out specific privacy policy recommendations for the city to consider.

Communicating with the Public
Resource Type:
Literature or Online Resource
Summary: The letter provides a set of recommendations for communities that are embarking on micromobility programs. It discusses the types of reporting that should be required; what types of data should be made available to the public; how privacy should be maintained through data aggregation before publishing data; and more general recommendations, such as recommendations related to equity, compliance tracking, and the use of surveys. The guidance is specific but not comprehensive.
Additional Details: Interestingly, this letter recommends against the use of third parties for data management and lists a variety of reasons for this recommendation. This recommendation runs counter to all other references included in this chapter that address the topic. All the other references recommend that this option at least be given consideration, depending upon the circumstances of the locality.
The letter includes a link to a public spreadsheet showing the various fees that cities charge providers of dockless mobility services, including per-vehicle fees, annual fees, application fees, and bonding requirements. As of February 2021, 20 communities were listed. It is not clear how up to date the spreadsheet is, but many of the rows include online links to the original sources.
The letter also recommends considering that service providers be required to distribute a city-designed survey to their users to provide insight into behavior patterns, preferences, and customer satisfaction. The survey used by Portland, OR, is linked to and recommended as a good model.

Description: Legal brief challenging the legality of LADOT requiring the provision of detailed, location-specific trip data from dockless mobility providers.
Topic Area(s):
Data Sharing Policies and Practices
Resource Type:
Literature or Online Resource
Summary: The brief challenges the legality of the collection of these data under the Fourth Amendment to the U.S. Constitution, the California state constitution, and the California Electronic Communication Privacy Act (CalECPA).
The brief is included in this chapter because it provides an excellent, detailed discussion of the privacy concerns raised by the collection of detailed, location-specific trip data, including numerous references that further demonstrate or discuss these concerns. It is included for its comprehensive discussion of legitimate privacy issues rather than the legal arguments.
Additional Details: The legal brief explains how location-specific individual trip data can be combined with other, publicly accessible data (such as who lives at a given address or what business is at an address) to reveal both the individual who took the trip and why the trip was taken (e.g., to visit a reproductive health clinic). The brief explains that these data are sensitive regardless of whether they are collected in real time or provided after the fact.
The brief also provides examples of how such de-anonymized data can harm an individual and examples of how location information has been abused in the past, as when automatic license plate reader information was used by stalkers and domestic abusers. Citations to research and reports with additional detail are provided.
Additional Resources: In February 2021, this case was dismissed on legal grounds by the judge, who ruled that collecting MDS data did not constitute a search in legal terms and that, even if it did, it was not an unreasonable one. As of June 2021, that ruling was being appealed. See Justin Sanchez et al. v. Los Angeles Department of Transportation, et al. (Gee 2021).

transit agencies that are considering implementing mobility on demand (MOD) or a similar integration with private mobility service providers, with a focus on data exchange requirements.
Summary: The paper outlines the types of information transit agencies might need, depending upon the type of project and its objectives. The paper then discusses the challenges that agencies have faced in attempting to obtain the data, including concerns over privacy, proprietary data, security, level of aggregation, data needed for the National Transit Database and to support federal funding, and the limitations of the agencies’ capabilities.
The paper then presents project-level, regulatory, and legislative options for overcoming these challenges. It includes a decision tree to aid agencies with sequential decision-making to determine the best approaches based on project type, project objectives, and constraints.
Additional Details: The paper states that reaching data sharing agreements between the public and private partners was one of the primary challenges of projects under FTA’s MOD Sandbox Program (FTA n.d.). Throughout the paper, specific MOD Sandbox projects are discussed as examples of data needs, challenges, and solutions. Much of the content is based on lessons learned from the MOD Sandbox Program.
The decision tree at the end of the paper addresses two types of projects: MOD service projects and Multimodal Trip Planning App (Smart Columbus n.d.) projects. Project- and policy-level decisions are identified in the tree, and the advantages and disadvantages of each decision are presented in a table. Decisions include whether to pursue modernizing public record laws, whether to manage data in-house versus by using a third party, and whether to establish a common API or pursue individual API agreements with each service provider.

Description: Short (seven pages) but detailed description of the methodology followed by Minnesota to manage and analyze data collected as part of a motorized scooter pilot program that ran from July through November 2018.
Topic Area(s):
Data Sharing Policies and Practices
Resource Type:
Literature or Online Resource
Summary: The focus is on how the state protected privacy and minimized any potential use or release of sensitive information through anonymization and aggregation. The license agreements between the city and scooter operators prohibited the city from obtaining any PII and required service providers to put good security practices in place to protect any PII that they collected as part of their operations. The agreements also laid out the city’s purpose in collecting the data, how the data were to be provided, what data the city would make publicly available, and what data each provider had to make available to the public.
Although no PII data were collected by the city, location-specific trip-level data were collected, and these data are potentially re-identifiable. The report describes the methods used by the city to minimize this possibility.
The methodology was developed to be consistent with the Minnesota Government Data Practices Act (Gehring 2010).
Additional Details: The city used a Python front end and a Microsoft SQL server to consume and store the data. Server access was restricted, as was access to the API authorization tokens. Python, R, and Tableau were used for analysis and visualizations.
The paper describes seven techniques that were used to anonymize the data, including the following:
The report describes several specific issues that arose, such as differing interpretations of standards, the absence of historical data in the GBFS (the project did not initially use the MDS), and bad data. The project used only GBFS data in the beginning. The MDS standard became available midway through the project, and this was incorporated into the data-reporting requirements. The specific MDS and GBFS data fields used in the pilot are provided and discussed in the two appendices to the document.

Summary: The MDS standard does not support collecting PII; however, it does support collecting detailed trip data that could potentially be combined with other data to re-identify individuals. This guide describes a method for ensuring data collected using the MDS is sufficiently anonymized so that it cannot be used for this purpose. The resulting datasets can be published or released via open data requests without fear that individuals can be identified from the data.
Additional Details: Trip start and end time data are binned into 15-minute increments. The geographic location data are both binned and fuzzed. The data are first binned by truncating the latitude and longitude data to three decimal places. The data are then fuzzed using a k-anonymity generalization function that groups multiple similar trips together and replaces their individual origins and destinations with the prototypical origin and destination for that group. This fuzzing is only done for trips for which fewer than five trips were made between the origin and destination bin pair. The entire process is described in detail, with SQL and other sample code provided and described. The processed data can be seen on Louisville’s public dashboard (City of Louisville, KY n.d.-b). The guide also provides links to open data from six other localities and a general description of how each anonymizes its published data.

Summary: The document discusses the challenges of balancing the need for information with providing adequate privacy protection. It has an excellent discussion on how geospecific trip data can become PII—the reason such data need to be treated as sensitive information.
The document defines and discusses four principles for managing mobility data: public good, protected, purposeful, and portable. Specific, actionable best practices for public agencies are provided to put each principle into practice. Additional, more detailed best practices for data governance and data management are also provided. The document concludes with examples of the types of questions that public agencies wish to address through the collection of mobility data, broken out into planning, oversight, analysis, and enforcement topics.
Additional Details: As an example, the “purposeful” principle is defined as the need for clear definition of the types of questions the organization is seeking to answer and to map data requests to those needs. Four high-level recommendations are discussed, including developing an internal capacity to audit the data to ensure their accuracy.
Specific, bulleted examples of best practices, such as “aggregate all geospatial data before committing it to permanent storage” are provided for seven areas: storage, sharing, access, oversight, expanding staff capacity, data aggregation, and common data queries.

Description: Thirty-seven-page primer on data policies and practices for shared mobility systems.
Summary: While written for Oregon communities, the content is applicable to any locality, the guide is easy to read and provides an excellent introduction to the topic while giving specific, actionable advice.
Additional Details: The guide consists of an executive summary, a glossary of terms, five chapters (“Understanding Shared Mobility Data,” “Policy Development,” “Collection of Recommended Mobility Data Practices,” “Summary of Third-Party Data Analysis Tools,” and “Information Resources”), and an appendix that provides sample licensing terms for various types of shared mobility services across the country. The first chapter provides an explanation of open data specifications and open data that is very easy to read and understand and then describes the roles and capabilities of the GBFS and MDS. The second chapter draws on the decision tree in Objective-Driven Data Sharing for Transit Agencies in Mobility Partnerships (Shared Use Mobility Center 2019a) to lay out and define a four-step process for developing data sharing policies: (1) lay the groundwork, (2) establish the purposes for shared mobility data, (3) clearly define the data scope and data protection policies, and (4) draft the data policies. Guidance is provided on each of these steps. The third chapter goes into some detail on seven recommended practices:
The fourth chapter contains a unique table of six shared mobility data management dashboard products. The table includes the distinguishing features of each product, the cost for some of the products, and examples of locations that are using each product. The final chapter briefly describes eight references to investigate for additional information, many of which are also described in this chapter.

Summary: The report discusses issues associated with data sharing in some detail and includes good examples of each. It also presents overviews of the GBFS and MDS standards and the rationale and state of the practice at the time for third-party data management. The report concludes with a set of specific recommendations and options for TransLink to consider.
The shared mobility data sharing environment is evolving rapidly. Although this study is only a few years old, its somewhat negative view of the MDS reflects the then-new and not yet widely adopted status of the standard. This had changed over the 2 years between the publishing of Lempert’s report and the writing of this chapter; however, the concerns expressed on the viability of some of the third-party data providers remained accurate as of early 2021.
Additional Details: The report discusses two major sets of issues with data sharing: the private sector’s concerns with sharing its proprietary data and privacy concerns. The report includes several instructive real-world examples of how location data can be re-identified and why location data may reveal sensitive personal information. It describes how bike- and scooter-sharing services have generally been more willing to share data than TNCs.
The report then introduces the GBFS and MDS standards, their relationship to one another, and their uses as well as their benefits and challenges. The MDS has evolved somewhat since the summary provided in the report. The discussion and examples of the challenges with implementing MDS are good but also dated. For example, it cites Washington, DC’s, initial decision that MDS was too complex to implement; however, this decision was changed in 2020, with a new requirement that service providers implement an MDS API for obtaining data.
The report’s discussion of SharedStreets provides a good introduction to the SharedStreets Referencing System in addition to discussing SharedStreets’ roles as a data aggregator and analytics provider.

Description: Short article describing the dockless bikeshare program run by the Boston area Metropolitan Area Planning Council (MAPC) as well as MAPC’s approach to data sharing with Lime, the bikeshare service provider.
Summary: The goal for data sharing was to better understand how dockless bikesharing was being used and then to use the results to inform policy and investment decisions. After 18 months, MAPC analyzed 300,000 trips covering 380,000 miles.
Additional Details: The analysis showed that about 20% of trips were on “very high stress roadways” with high traffic volumes, multiple lanes in each direction, and no protected bike lane infrastructure. In many cases, there were few or no alternate routes for these portions of a trip. These results are being used to prioritize infrastructure investments.
More than half of the riders were not primarily bike riders, that is, they either had not ridden their own bike in more than 30 days or did not own a bicycle. Fifteen percent of trips began or ended at a transit station, which indicates that while last mile trips were a significant minority, they were not the primary reason for choosing a bikeshare. One-third of trips began and ended in different localities, which shows the importance of coordination across jurisdictions. The full report on the analyses is listed under “Additional Resources.”

Summary: The CDS-M is a proposed alternative or modification to the MDS that is under development in the Netherlands. It is intended to address specific European needs, including use of standardized European vehicle classification systems and compliance with the General Data Protection Regulation (GDPR).
The paper describes needs for quantitative data from each of five Dutch cities, so that these can be turned into requirements that the CDS-M standard must address. The use cases are divided into policy, planning, and enforcement. For each sufficiently defined policy question, the paper then provides the purpose of the need, the type of analysis (at an extremely high level), and the specific data that the standard would require to be provided. The paper dives deeper into a specific use case in Utrecht, which is interested in the extent to which shared electric carrier bikes will save on short car trips. The relevant need definitions are mapped to this use case.
Additional Details: The needs are formatted in the form of policy questions. Examples of the included use cases include the following:

Charlotte implemented a 6-month trial period of a dynamic pricing system for service providers rather than a flat per-vehicle charge.
Additional Details: For the dynamic pricing pilot, the city was divided into different zones with different prices to incentivize access to transit and discourage overconcentration in congested areas. In addition, the fee varied by how long each vehicle was parked. Hot spot visualizations of the data helped the city determine where scooter corrals should be located.

Resource Type:
Sample Document or Agreement
Summary: The data sharing agreement requires permit applicants to agree to provide certain information, in specified formats, to either the city of Portland or a city-identified third-party researcher. In addition, applicants must agree to distributed user, employee, and contractor surveys developed by the city. The administrative rules cover the pilot program that was in effect at the time this chapter was written, running from April 26, 2019, through June 30, 2021. Section 4 describes the metrics terminology used for reporting, and Section 7 of the administrative rules covers the data requirements.
Additional Details: The data sharing agreement requires permit holders to provide MDS data as well as a publicly available API for accessing data in the GBFS format. This is an update from Portland’s 2018 pilot permit application, which defined the API in an appendix to the permit application instead of referring to the MDS. The 2018 pilot program also did not have the requirement for a public GBFS feed.
However, the permit application references the Portland version of the entire MDS, which, as of January 18, 2021, appeared to be a copy of an earlier version of the Open Mobility Foundation version. It does not specify specific portions, which may imply that all portions relating to data originating from the mobility service provider are required. Similarly, while a public API to files “consistent with GBFS standards” is required, the elements that are or are not required are not called out in the permit application.
The agreement includes language stating that if the city receives a public records request or is sued to release confidential information, or if a court determines certain information is not confidential or a trade secret, the city will notify the mobility service provider so that it can take steps to prevent disclosure. The agreement states that “city-identified third-party researchers” will be working with the city to help evaluate the pilot program.
In the section on data requirements in the administrative rules, the specific metrics discussed in Section 4 and the API requirements in Section 7 are incorporated by reference to a GitHub site maintained by the city (https://github.com/CityofPortland/mobility-data-specification).
This gives the city the flexibility to make changes without needing to redefine its rules at the elected official level, thus streamlining the process. Many other cities are taking a similar approach.

Summary: This document lays out the data-reporting requirements that must be followed by shared micromobility operators in Minneapolis’ pilot program. It lays out the requirements for operators to provide APIs for MDS and GBFS data feeds and for the operator to conduct two customer surveys using questions provided by the city. The city reserves the right to require that the operator provide an API that may be shared with a third party to facilitate the city’s mobility-as-a-service (MaaS) program.
Additional Details: The agreement lays out specific data that must be provided. In addition to the APIs and surveys, operators must also provide either a dashboard or a report that includes the following summary data: “number of Fleet Scooters distributed; total number of trips; trips per Fleet Scooter per day; number of new customers; total number of customers; total number of low-income program customers; average miles per trip; and average minutes per trip.” Falsified data or deliberately inaccurate reporting may be grounds for termination of the operator’s license.
The city may share any public data collected with other government entities for common public purpose objectives but will not share or disclose nonpublic data as defined under Minnesota law. The city agrees to abide by its Mobility Data Methodology and to inform operators of any substantive changes in advance of their implementation.

Summary: The MDS is a set of open, standardized APIs for two-way, automated exchange of information between micromobility service providers and public agencies. It has been adopted by more than 90 agencies across the world and by most major mobility providers. The inclusion of detailed, trip-specific data has been controversial, due to privacy concerns; however, agencies can choose which portions to implement, and providers support the use of a single reporting standard across cities.
Additional Details: The MDS currently has three sets of APIs:
Various open-source software tools have been developed to support the use of the MDS.

Standards Effort or Software Tool
Summary: The GBFS is, by design, an open standard for providing public, real-time, read-only data on bikeshare and shared e-scooter systems. It does not provide trip-level data or historical data. The GBFS was originally developed as a stand-alone standard for providing real-time information to consumers via an open, standard data feed. It can be used on its own for this purpose. The MDS is intended for private data exchange between providers and public agencies, contains historical data, and unlike the GBFS, may contain sensitive information. The data exchanged using the two standards complement one another, and, in fact, the MDS requires that providers also have a GBFS data feed.
Additional Details: The GBFS was originally developed by a volunteer at the North American Bikeshare & Scootershare Association (NABSA), working in collaboration with many public- and private-sector organizations (NABSA n.d.). In 2019, NABSA selected MobilityData to become the technical steward for the standard. NABSA and MobilityData continue to partner on the effort, improving the specification and its governance to meet evolving industry needs.
GBFS provides information on stations where vehicles may be located, available vehicles, operating locations, dates, hours, pricing, alerts, and more. A significant number of software tools have been developed to support the implementation and use of the GBFS.

Summary: SharedStreets is an open-source software package for ingesting MDS data feeds and aggregating the data in such a way that it is useful for analysis while also protecting privacy.
Additional Details: The software runs on either OSX or Linux (Windows users can either use a Docker image or Windows Subsystem for Linux). It is open-source software licensed under the MIT License. Raw data, which, per the MDS, may include detailed individual trip-level data (thereby raising privacy concerns) are aggregated and analyzed to produce multiple metrics. These include summary metrics and fleet-level snapshot metrics as well as geographic and time-filtered data. Summary metrics include the total number of vehicles on the street for a given day, the number of active vehicles for the day, average trips per vehicle, and average trip distance.
Mobility Metrics produces three fleet-level snapshot metrics: the number of vehicles deployed and available for use, the number of vehicles deployed but unavailable (e.g., a vehicle with a dead battery or awaiting maintenance), and the number of vehicles actively engaged in a trip. Filtered data can be produced by using a variety of different geographic and time filters and includes metrics such as trip volume, the number of vehicles available, and the number of pickups within the specified area and time frame.

Summary: SharedStreets, a nonprofit organization, developed and uses CurbLR, an open standard for digitized, georeferenced curb information. In addition to regulatory information, CurbLR maps curb-related assets such as wheelchair cuts, bus stops, fire hydrants, signage, crosswalks, bike racks, and other physical assets. CurbLR makes use of the SharedStreets Referencing System for location data.
Additional Details: The data exchange format for CurbLR is GeoJSON. An example of a curb feature coded in CurbLR format (in this case, a motorcycle-only paid parking space) is shown in Figure 12-1.
SharedStreets is working with the Open Mobility Foundation’s Curb Management Working Group to develop a uniform agreed standard for curb data, with CurbLR as an input to the process.

Summary: As shown in Figure 12-2, differing base maps often do not align, which makes it difficult to combine data from different sources. The SharedStreets Referencing System provides a common framework to solve this problem.
Additional Details: Organizations using the SharedStreets Referencing System maintain their own base maps and can share the nonproprietary information in their GIS. The system provides a stable, nonproprietary, base map and independent identifiers for identifying street segments, intersections, and geometries. Data are exchanged using these common identifiers. The types of data that might be exchanged or combined include traffic data, street and curb inventories (CurbLR makes use of the SharedStreets Referencing System), incident reporting, and road closure reporting.

This section provides information on five organizations that are active in providing resources related to shared mobility data. Three of these are membership organizations that public agencies may also wish to consider joining or in whose work they might wish to participate:
The other organizations are those that, in addition to other activities, serve as third parties for data management and analysis. SharedStreets is a nonprofit initiative, while the Transportation Data Collaborative (TDC) is an initiative of the University of Washington. There are also commercial third-party providers that offer similar data management and analysis services for shared mobility.

Summary: NUMO is a global alliance focused on urban transportation policies that benefit all residents. One focus area for NUMO is micromobility. NUMO has three major initiatives in this area: the Micromobility Policy Atlas (NUMO n.d.-b), the Shared Micromobility Playbook (Transportation for America n.d.), and “Micromobility & Your City: Leveraging Data to Achieve Policy Outcomes” (NUMO 2020).
Additional Details: The NUMO Micromobility Policy Atlas tracks micromobility programs around the world. As of January 2021, it tracked dockless scooter, bicycle, and moped deployments across 626 cities in 53 countries, which includes 127 mobility service providers. The data are all open-source and available for download.
The Shared Micromobility Playbook (Transportation for America n.d.) is a policy guide for communities and addresses eight topics:
The Micromobility & Your City project has produced Leveraging Data to Achieve Policy Outcomes, an interactive, web-based tool for selecting outcome measures of interest, defining specific metrics for each outcome, and identifying the data needed for the metric (NUMO n.d.-a). The focus is on safe, sustainable, and equitable services.

Organization
Summary: The Open Mobility Foundation intends to “create and manage a set of model policies, privacy and data security, procurement, and technical guidelines.” It was founded to take over the governance of the MDS, which was originally developed by LADOT. The MDS is a specification for APIs to allow for mobility service providers to provide information to government agencies and for government agencies to provide both static and dynamic information (e.g., temporary street closures) to service providers.
While the MDS was originally written to cover shared scooters, it can be used in its current form for other micromobility services as well. One of the Open Mobility Foundation’s goals is to explore either expanding the scope of the MDS or developing related APIs to cover other shared mobility modes such as TNCs.
Additional Details: In addition to multiple working groups focused on various aspects of the MDS, the Open Mobility Foundation created a Curb Management Working Group to work on developing common data definitions and API specifications for digital, geocoded curb assets, regulations, and occupancy (OMF 2020a). In addition, the Open Mobility Foundation has a Privacy, Security, and Transparency committee, which published Mobility Data State of Practice, an extensive inventory on the state of the practice of location data privacy and anonymization (OMF n.d.-c) and Privacy Guide for Cities (OMF 2020b). The organization is developing a set of privacy principles to guide future work by the foundation.
The Open Mobility Foundation has both public- and private-sector members; however, board members must come from the public sector. As of January 2021, its website listed 31 public-sector members, most from the United States, but also non-U.S. members such as Ulm, Germany, and Bogota, Colombia. Nine private-sector members are listed, including service providers (e.g., Bird), data management organizations (e.g., Ride Report) and others (e.g., Ford Autonomous Vehicles LLC).

Organization
Summary: SharedStreets has a number of different projects and programs, including the
SharedStreets Referencing System for allowing data to be transferred between different base maps; CurbLR, an open data standard for georeferenced curb data; Mobility Metrics; and open-source software supporting these initiatives. In addition, SharedStreets functions as an independent third party for managing and analyzing data.
Additional Details: The SharedStreets Referencing System provides an open, common referencing system that can be used to convert data from one base map to another, so that data from different geographic reference systems can be effectively combined and analyzed. CurbLR is one of several initiatives for standardizing digital, georeferenced curb locations, rules, regulations, and usage.
One example of SharedStreets’ function as an independent third party for managing and analyzing mobility data was the Washington, DC, Data Sharing Partnership. The District Department of Transportation and the Washington, DC, Department of For-Hire Vehicles teamed with SharedStreets and Uber to launch a data sharing and data analysis partnership under which Uber agreed to share data that might be privacy sensitive or proprietary with SharedStreets, who agreed to use the data only for specific, agreed-to purposes and not redistribute it. SharedStreets then used the data to provide both aggregate data and analysis results to the city government (Marshall, 2018).
This model—using a trusted third party—holds promise for helping to allow localities to receive the data analysis that they require while protecting the data from, for example, state FOIA requests or other concerns with government possession of the data (e.g., its use for law enforcement).
While SharedStreets is a nonprofit organization, there are also for-profit companies and university programs, such as the University of Washington TDC, working to establish themselves as trusted third-party data managers and analysts.

Summary: The goal of the collaborative is to provide a common protected and linked repository for both public- and private-sector data. The concept is that data can be managed, protected, analyzed, and, where appropriate, shared more efficiently and effectively by a single collaborative organization with a common set of policies and procedures.
The TDC identifies the following barriers to data sharing that third-party management can help overcome:
Additional Details: TDC currently provides services to the city of Seattle, WA. Seattle planners want access to census block-level data on shared mobility to better understand impacts such as curb usage but recognize the need to protect privacy and that Washington state’s open records laws currently do not fully protect location-specific trip data that might have to be disclosed should they be stored by city agencies. TDC is looking to expand its services to other major metropolitan areas.
In addition to TDC, which is operated by a university, there are other nonprofit organizations, such as SharedStreets, and for-profit organizations that provide third-party shared mobility data management and analysis services.

Use of Third Parties for Data Management
Resource Type:
Organization
Summary: These types of organizations are typically hired by a public agency. Operators are required to provide their data to the third party, which processes, stores, and analyzes the data. The third-party provides metrics, analysis, and visualizations as well as public and private dashboards for the public agencies that hire it.
The third-party providers have experience dealing with multiple operators across multiple jurisdictions and can provide public agencies with data collection, standards, data management, security, and analytic expertise that they may not have in-house. In addition, this model holds promise for helping to allow localities to receive the data analysis that they require while protecting the data from, for example, state FOIA requests or other concerns regarding government possession of the data (e.g., its use for law enforcement). Mobility operators may be more comfortable working with a third-party provider that they have worked with in other communities than dealing with a new (to them) provider and municipality.
Additional Details: The scope of services provided varies with the provider. Some only cover micromobility services, while others also cover additional forms of shared mobility, such as car sharing, and even transit systems. Some provide digital geographic tools for curb and street management and for communicating regulations and changes to outside parties. Some of the companies support the collection of operating fees that localities may place on mobility operators, and some also support parking enforcement. In addition, these companies will audit the reports provided by mobility operators, checking that they are accurately reporting ground truth.
Additional Resources: None.
This section provides links to eight representative public datasets, visualizations, and dashboards available on the Internet. It includes examples of micromobility, TNCs, and taxi datasets.
An important consideration is that there is a clear understanding and agreement between agencies, operators, and third-party data managers (if any) as to what data and which metrics are publicly shareable versus what needs to be kept as internal data available only to the agency. Metrics that may be appropriate to share publicly may include (M. Schwartz, personal communication, June 2021):

There may still be issues with aggregated data, however, and care must be taken. For example, if there are only two providers of a type of service, aggregated data will provide insight into each other’s operations, as each provider can simply subtract out its own data.
