gtfspy

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 interst.
• 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 3.5
• Supported platforms: Linux + OSX (Windows is currently not supported, please creat an issue in Github if you would be interested in running gtfspy on Windows)
• Optional: git is used for development.

Install

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.

Examples

• Importing a GTFS feed into a sqlite database
• TODO: Validate an imported feed
• Compute and plot temporal distance profiles between an origin--destination pair
• Visualizing the public transport network on map
• Filter GTFS feed spatially and temporally
• Extract a network / a temporal network from the GTFS database
• TODO! Run a simple accessibility analysis pipeline!

Versioning

This library is not yet stabilised, and new features are being developed. Thus code organization and interfaces may change at a fast pace. More precise versioning scheme will be decided upon later.
