OSRM Lua profile for trains
This repo contains a profile for routing (mostly freight) trains with OSRM. This enables you to find the shortest path by train between 2 points and also do map matching with OSRM.
Note: travel time estimations are way too optimistic due to the red lights, stations and traffic not taken into account
Right now, it contains, 2 profiles :
basic.lua
A basic/naive profile that works quite well.
freight.lua
A profile optimized for freight trains:
- Default speed is 130 km/h
- Highspeed lines are de-prioritized
- Has flags to completely exclude highspeed lines and/or non electrified segments
- Rejects all gauges that are not 1435mm
Possible improvements that we might one day include :
- Preferred left-hand driving even where OSM does not specify it (if you know how to implement it, please be in touch !)
- Better turn restrictions/penalties
- Speed limitation in curves
- Time penalty for traffic lights or when passing trough stations
Inspiration for the code taken from an old russian blog and the car profile
How to run this?
First, you will need to install the Docker daemon and osmium (osmium-tool on Ubuntu) on your machine.
Then, run make all to download the OSM data, filter and combine it and finally compute the routing graph.
Last, run make serve to serve the OSRM server locally on port 5000
