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
