GTFS Builder Getting Started Guide
This document provides a self-guided tour of National RTAP’s GTFS Builder for General Transit Feed Specification (GTFS) data management.
GTFS Builder includes simple Excel-based data management tools and instructional videos. The instructional videos will walk you through gathering and inputting your transit stop locations, bus routes and schedule data into the GTFS Builder Excel files. This guide complements screenshots and live demonstration in the videos. Once your data is output as a .zip file, you will validate it, request an account to test your data and upload the file so that it can be sent to Google Transit and other trip planners and much more.
First Things First
You must have a Cloud Account to log into National RTAP in the Cloud and have access to GTFS Builder. If you do not have a Cloud Account, you can create one by clicking the “Cloud Signup” button in the top right corner of this page and following the step-by-step instructions. If you already have a Cloud Account, you can log in using the “Cloud Login” button also in the top right corner of this page. Once logged into the Cloud, you will see GTFS Builder listed in the left toolbar.
Overview Videos & Two Excel Workbooks
The three one-hour Step 1, 2, and 3 Workshop Webinars walk you through the process of getting your route and schedule data into a trip planner application like Google Transit. For staff ready to jump in, you can view the components of these webinars broken into brief (2-5 minute) instructional videos. The workshop webinars and instructional videos are located in the GTFS Builder Support Center on the Instructional Videos page for each step.
Before you begin the process of gathering your data and downloading the various tools you will need, we suggest you watch the following videos:
- Should My Agency Proceed with GTFS Builder? (available on the GTFS Builder landing page)
- Summary View of Files Generated and Common Terms (available on the Archived Videos page)
GTFS Builder manages data using two Excel spreadsheets, which are part of the GTFS Builder toolkit that you download from the Dashboard in the Cloud:
- SchedulesV2 (to generate and manage schedules)
- Import Export (to generate all the required files)
The following additional resources and links may also answer questions you have regarding GTFS Builder:
