| Text Responses for “Other” |
|---|
| Vissim/Vistro is kept up to date, Synchro/SimTraffic is every 2-3 years. |
| As part of the license agreement with the software developer, we get the new version as it becomes available. |
| I would say every 2 or 3 years. |
| Depends on the software. |
| We download the most recent versions every time its released. |
| Depends on when software gets updated and length of procurement. |
| Depends on update schedule, costs, etc. |
| There is not really a policy for changing software with NMDOT. Usually, the choice of software is made by a consultant and is based on their expertise. |
| Depends on the software (average 2-4 years). |
| We evaluate the software and then decide to change version, it varies from software to software. |
