Below are some of the additional resources available in support of GTFS Builder:
There are other options if your agency wants to maintain the GTFS data, but not prepare all the initial files. A few of the companies that build and manage GTFS data for transit agencies are listed below. You can also see a list of vendors offering GTFS services on this public online spreadsheet.
NOTE: these companies are not endorsed by National RTAP and this is not a comprehensive list. Please do your own research before making a decision or starting procurement.
If when writing your contract with these companies you ask that the files be returned to you, you could maintain your data using GTFS Builder with some additional data transformation.
Some agencies have found after building their GTFS data that they are not able to maintain it. For those cases, some companies offer customized and targeted GTFS data support services.
