Open source IDF router for QGIS

This is a follow-up on my previous post introducing an Open source IDF parser for QGIS. Today’s post takes the code further and adds routing functionality for foot, bike, and car routes including oneway streets and turn restrictions.

You can find the script in my QGIS-resources repository on Github. It creates an IDFRouter object based on an IDF file which you can use to compute routes.

The following screenshot shows an example car route in Vienna which gets quite complex due to driving restrictions. The dark blue line is computed by my script on GIP data while the light blue line is the route from OpenRouteService.org (via the OSM route plugin) on OSM data. Minor route geometry differences are due to slight differences in the network link geometries.
