[Routing] Average speeds, Fastest Paths in Contraction Hierarchies

[Curt Nowak]

Thanks Christian and Markus for the quick replies.
I'll have a look at the MoNav code.

Hi everyone,

I'm developing a routing application using Contraction Hierarchies. Trying to implement fastest path queries I'm currently facing two problems:
1: What average speed should I assume for different highway types (, and vehicles, and countries....) ?
2: Has anyone already solved this for Contraction Hierarchies and if so, how do you extract travel times for a shortcut edge that may span over multiple highway types and even countries?

So far, I could not find a lot in the web - not even for question 1. Any pointer (or link) would be greatly appreciated.

Curt


Avg.speed: outside cities legal speed of the current country +10, inside -20km/h
Penalties for sharp curve/traffic light/rush hour,
Bonus for multiple lanes.
...have fun coding this ;)
