[OSRM-talk] Issue with chosing a sub-optimal route

[Rudolf Mayer]

Hi all!

I'd have a question regarding this routing:

http://osrm.at/att

This is suboptimal, as it is longer, should be slower, and requires 
turning.

Specifically, OSRM proposes to turn off the main street via a smaller 
residential route.

Ideal should be http://osrm.at/atu, which however gets a slower time 
computed - and I don't really understand why...

- Both ways have the same speed limit (ro:Urban)
- The second option is shorter

=> still it takes longer according to OSRM.

any ideas why?

thanks,
Rudolf
