GTFS (General Transit Feed Specification) Builder

GTFS Builder iconTrip planning technology (the integration of transit route and schedule data on a map) enables riders to determine how to use transit to get where they need to go. How can your agency bring trip planning technology onto your website? It seems complicated, but the information you already collect may move you one step closer to having that technology. GTFS Builder helps you complete the final steps.

National RTAP partnered with the Marcy Jaffe Company to bring you GTFS Builder - a free web-based tool to help you create GTFS files to post on trip planning sites such as Google Transit.

GTFS Builder 3-Step Process Overview

The first step of GTFS Builder is to determine the location of your bus stops, by finding the latitude and longitude of each stop along a bus route, and entering them into the GTFS Builder Excel spreadsheet. The next step is to input all of your schedule data into the spreadsheet. The final step is to validate your data to make sure it works within the trip planner. Once your data has been validated, you set up the file to be launched on Google Transit.
