gtfspy

Gtfspy-master Travis CI build passing PyPI badge

gtfspy is a Python package for analyzing public transport timetable data provided in the General Transit Feed Specification, GTFS, -format.

Core features:

  • Import one or multiple GTFS feeds into one SQLite database for efficient querying of the data.
  • Augment the sqlite with real walking distances between PT stops using Open Street Map (OSM) data.
  • Compute simple statistics for the public transport networks such as number of stops, routes, network length.
  • Filter databases spatially and temporally to match your area and time region of interest.
  • Perform accessibility analyses using a routing/profiling engine
    • Adapted from the Connection Scan Algorithm (CSA).
    • Compute all Pareto-optimal journey alternatives between an origin-destination pair, and summarize connectivity with measures on travel time and number of transfers.
  • Produce data extracts in various formats (network edge lists, geojson).

Prerequisites

  • Python 3.8
  • Supported platforms: Linux, OSX & Windows
  • Optional: git is used for development.

Install

Linux and Mac OS

pip install gtfspy

Windows

Windows should work, but has not been tested or and may not be supported as much. Please report problems.

Windows users may need to install Shapely library first. Download Shapely wheel and then run:

pip install wheel
pip install {path to the Shapely wheel file on your PC}

If you come across the Microsoft Visual C++ 14.0 is required error, you may need to download the latest Microsoft Visual C++ Build Tools. You can download it from here.

After that, continue with:

pip install gtfspy

Development quickstart

Use this if you want to be able to edit gtfspy's source code.

git clone git@github.com:CxAalto/gtfspy.git
cd gtfspy/
pip install -r requirements.txt # install any requirements
nosetests . # run tests

Remember to also add the gtfspy directory to your PYTHONPATH environment variable.
