PGTFS

About

PGTFS is a PostgreSQL extension designed to facilitate routing on top of the GTFS (General Transit Feed Specification) format. It provides functionality to query and analyze public transportation data stored in a PostgreSQL database using GTFS feeds.

Why PGTFS?

While there are several projects that support routing using GTFS feeds, I felt the need to build something as simple as pgRouting, but for GTFS feeds. The extension capabilities of PostgreSQL made this an easy choice.

Who is it for?

The first version of the PGTFS extension is a proof of concept, the purpose is to add support for the most common used algorithms within public transportation / GTFS feeds. As such, it is currently suited for research purposes and products that perform routing at a city-scale.
