PyCon.de: public transport efficiency with geopandas and GTFS - Pieter Mulder¶
(One of my summaries of a talk at the 2017 PyCon.de conference).
Pieter Mulder works at dooor2door on a ride-sharing platform. He works on the research into demand.
He uses:
geopandas, which extents pandas with a geometical column type (using ‘shapely’).
You can even reproject a geometry series from one projection to another.
GTFS: generic transit feed specification. It is defined by google: a common format for transportation schedules and associated geographical information. It isn’t scary, it is basically a zipfile with a bunch of csv files.
Geonotebook: adds a map to your jupyter notebook with two-way interaction.
He then showed a demo with jupyter. Extracting all stops from local Karlsruhe GTFS files. Plotting them on the map. Searching for bus or tram stops within 5 minutes walking distance. Finding the stops you can reach with a trip of max half an hour.
Nice demo!
(Something similar is being done with opentripplanner (written in java).)
