APPENDIX B

Survey Analysis

B.1 Overview

An Airport Parking Reservation Systems and Techniques survey (“the survey”) was developed to assess the benefits, costs, and operational and financial results of airport online parking reservation systems. The survey was hosted by Steer using Microsoft Forms (Figure B.1).

A screenshot of an online survey form titled Airport Parking Reservation Systems and Techniques. The form includes a brief description of the project and displays two questions. Question 1 asks for the respondent’s airport IATA code, followed by a text box for entering the answer. Question 2 asks whether the airport offers customers the option to reserve parking through an online booking system, followed by Yes and No response options.

B.4 Survey Results

The average survey completion time was just under 28 minutes. The following section details the response for each of the 17 individual questions as introduced in the preceding section.

Question 1: Please identify your airport (IATA code) - if you are affiliated with an airport operator that runs multiple airports, please fill in separate entries for each airport.

Question 2: Does your airport offer customers the option to reserve parking products through an online booking system?

As illustrated in Figure B.3, 17 respondents offer customers the option to reserve parking products through an OBS, while one operator respondent reported not having one. This operator previously had an OBS but removed it.

A horizontal bar chart with two response categories listed from top to bottom. The first bar is labeled Yes with a value of seventeen, and the second bar is labeled No with a value of one.
Figure B.3. Responses to Question 2 of the survey, “Does your airport offer customers the option to reserve parking products through an online booking system?”

Question 3: If available, what are the costs for equipment and other capital costs associated with the online booking system?

Responses have varied from a fixed annual implementation fee to a per transaction fee. The responses vary depending on how these systems are procured and/or operated and whether other components beyond an OBS were purchased.

For instance, one airport procured this system based on a term agreement with a fixed implementation fee, while another airport purchased its OBS system with other parking and garage improvements.

The following lists the responses received. For commercial sensitivity reasons, vendor names and specifics have been removed in the responses. Provided costs are assumed to be real at the time these airports implemented their OBS.

  • Three-year agreement [ . . . ] with [ . . . ] option years. Implementation fee - $25,000.
  • PARCS $4 [million] + Parking Guidance System $8 [million] + Garage improvements $10 [million] = $22 [million].
  • None. Our reservation program partner [ . . . ] set it up and charges us a fee for every transaction.
  • PARCS equipment was already installed. [$50,000] for system implementation.
  • It is provided by [the vendor] who has a contract with [another vendor].
  • Not available. The only hardware costs are the AVI scanners.
  • The system is online and managed by our parking operator. There are no equipment and/or capital costs associated with this change, only software development and monitoring of the website/program.
Suggested Citation: "Appendix B: Survey Analysis." National Academies of Sciences, Engineering, and Medicine. 2025. Airport Parking Reservation Systems and Techniques. Washington, DC: The National Academies Press. doi: 10.17226/29030.
  • The cost to integrate [the vendor’s] parking reservation system [ . . . ] with [the PARCS system] was approximately $25,000 plus the bar code readers [for a total approximate capital cost of] $42,200.
  • The costs for equipment and other capital expenses associated with our online booking system are as follows: 5 Entry Lane Stations with QR Code Readers at $10,831 each, totaling $54,155. 1 Exit Lane Station with QR Code Reader, totaling $11,713. 3 Exit Lane Transaction Panels with QR Code Reader at $7,278 each, totaling $21,834. 3 Exit Lane Booth Handheld Scanners with QR Code Reader at $411 each, totaling $1,233. Equipment Installation $9,888, and Shipping $2,382. Grand total, approximately $101,205.
  • Implementation was $164,138.
  • None, because our system is new (November 2019) and was part of the initial capital purchase of the new system.
  • Provider covered infrastructure [expenses].
  • We do not have any equipment costs, as our PARCS equipment integrates with our Parking Reservation system. [ . . . ]

Question 4: If available, what are the operating expenses for the online booking system for airport and/or contract staff?

Responses varied from a fixed annual fee to a per transaction fee. As per the responses in Question 3, the operating costs vary depending on the scope of the contract with the vendor. For example, some airports procure the OBS as a standalone product, while others have this as part of a broader parking operations contract.

The following lists some responses:

  • [$0.50] per transaction for both bookings and customer registrations [with a] $1,500 minimum monthly fee per month.
  • [$570,000 per year] and [marketing of $1.6 million per year] for a total of [$1.6 million per year].
  • Annual OBS fixed costs, transaction fees, and SMS texting of [approximately $55,000] annually.
  • None. [The airport] added reservation parking to the existing parking program, so there were not [any] additional operating costs that incurred from adding this product.
  • [$250,000 Commercial Management] Cost [and Management Fee of $400,000. Annual Fees (such as credit card transaction and payment service provider fees, texting, hosting, loyalty, etc. vary)] based on the number of online reservations.
  • [The airport] currently [has] a software agreement with our reservation provider where [a pay per transaction fee] is based on a tiered pricing structure.
  • On average, approximately $5,000 per month.
  • Operating expenses for the online booking system are based on transaction volume, transaction fee range is $0.50 to $1.65. [ . . . The Airport pays] for the transaction fee as part of the reservation booking fee. Contract staff expense to operate the booking system is approximately $55,000 annually.
  • The operating expenses for the online booking system for contract staff are approximately [$126,000] per year.
  • Approximately [$200,000] annually for the system.
  • Annually Operating Platform Expense - $35,000 Parking Operator Staff Expense - $1,040 per year ($20 per hour × 52 hours a year)[, ] [ . . . ] Staff Expense - $13,000 per year ($50 per hour × 5 hours per week × 52 weeks)[, and] Consultant Expense - $11,700 per year ($300+$150 per hour × 26 hours a year).
  • 2.99% credit card fee plus a reservation fee of $1.99 per reservation. For 2023, [the] total expense was [approximately $79,000].
  • [$2,000] per month for website, support, and analytics.
  • Set-up costs were approximately $25,000, and we have annual costs of $30,000 [ . . . ] to operate our reservation system.

Question 5: What percentage of parking inventory does your airport currently make available through the online booking system? Please provide a percentage breakdown on a per product basis.

Each airport has provided a wide range of responses. Due to commercial sensitivity, detailed responses have not been provided. However, in summary:

  • Some airports outsource these types of decisions to their parking operator, while other airports have fixed proportions that vary by product.
  • Most airports tend to make between 10% and 40% of the total parking and valet capacity available for reservations.
  • A few airports do not restrict the capacity made available through online parking reservations.

Question 6: Does this inventory change over time? For instance, a lower proportion of inventory is made available during peak holiday travel.

Figure B.4 provides a summary of the responses. Most airport operators (15) make changes in parking inventory that is reservable in the online parking reservation system, while two airport operators do not make changes to parking inventory at the time of the survey response.

A horizontal bar chart with two response categories listed from top to bottom. The first bar is labeled Yes with a value of fifteen, and the second bar is labeled No with a value of two.

Figure B.9. Responses to Question 11, “Does your airport capture customer data through the online booking system into a customer relationship management (CRM) system?”

Question 12: Is this information used to offer (or push) discounts for future parking?

Among the 10 airport operators that capture customer data into a CRM as per Question 11, as illustrated in Figure B.10, eight of those airport operators surveyed use the information to offer or push discounts for future parking reservations.

A horizontal bar chart with two response categories listed from top to bottom. The first bar is labeled Yes with a value of eight, and the second bar is labeled No with a value of two.
Figure B.10. Responses to Question 12, “Is this information used to offer (or push) discounts for future parking?”

Question 13: Is this information used to offer other discounts for airport services?

Among the 10 airport operators that capture customer data into a CRM as per Question 11, as illustrated in Figure B.11, apart from one airport operator, most airport operators have not yet used this information to offer (or push) discounts for other airport services.

A horizontal bar chart with two response categories listed from top to bottom. The first bar is labeled Yes with a value of one, and the second bar is labeled No with a value of nine.
Figure B.11. Responses to Question 13, “Is this information used to offer other discounts for airport services?”

Question 14: Do you have data that suggests the online booking system has increased the parking share of customers accessing the airport (for example, as against other modes such as on-demand ride app services)?

As illustrated in Figure B.12, the majority (nine airport operators) of responses do not have data that suggests online booking systems have increased the parking share of customers accessing the airport, while eight have and track for that data.

Question 15: What benefits has the online booking system provided the airport?

Figure B.13 lists the different response choices (multiple selection) and the number of respondents that agreed with the option. Improvements to customer experience appeared to be the benefit that applied across most airport operators. Meanwhile, the majority of airport operators have observed improvements to parking utilization (or occupancy) of parking facilities as a result of a parking OBS, with the same number highlighting that the future demand data is a benefit for the airport. Fewer airport operators (11) noted that the additional customer data is a benefit, and even fewer (seven) noted that airport OBSs have increased revenues compared to pre-OBS integration.

A horizontal bar chart with six response categories listed from top to bottom. The first bar is labeled Improved customer experience with the value of sixteen, the second bar is labeled Provided forward demand data with a value of thirteen, the third bar is labeled Improved utilization of parking facilities with a value of thirteen, the fourth bar is labeled Provided additional customer relationship management data and insights with a value of eleven, the fifth bar is labeled Increased revenues compared to pre-OBS integration with a value of seven, and the sixth bar is labeled Other with the value of four.
