GTFS JP Kit

GTFS JP Kit is a fork of GTFS Kit by Alex Raichev. GTFS JP Kit is a Python 3.10+ library for analyzing General Transit Feed Specification (GTFS) data in memory without a database. It adapts and extends the original library to support the GTFS JP transit data specification and related workflows, as defined by MLIT.

The original GTFS Kit (© Alex Raichev, 2019–present) is licensed under the MIT License. This project remains under the same license.

It uses Pandas and GeoPandas to do the heavy lifting.

Installation

uv add gtfs_jp_kit

Examples

Examples can be found in the Marimo notebook notebooks/examples.py.

Install dependencies and run the notebook as follows from the project root:
