OSRM Routing service Update
Posted by martinum4 on 14 September 2017 in English. Last updated on 15 September 2017.Hello everyone,
my OSRM-based Routing service will be down for maintenance on Saturday, I’ll update it from OSRM 5.5.0 to 5.11.0, besides a number of bugfixes this update will include a nice set of new features, for example excluding certain types of (predefined) way-types, more Algorithms and a new API-Level.
Regarding the runlevel exclusion of certain types I’d implement only motorways, trunks, ferries and toll routes, due to the fact that each type adds some processing time, how much exactly i can only tell after fully implementing everything.
Kind regards
Martin

This sounds great! I’ve had a lot of fun using your routing program, but sometimes would be bewildered as to why minor roads were selected in the routes, when freeway alternatives were available. Thanks for your work on this feature, which adds an extra layer of realism to our OGF world.

Thanks for your feedback :)
It may depend on multiple factors, for example left turns and traffic signals are penalized a little bit, maybe you didn’t set any maxspeeds, see here for information on which highway-type is assumed with which default speed or maybe your roads don’t share nodes. Thilo was so kind and used his javascript-skills to create this for further routing-graph-information on the exact speeds and times used.
Maybe you could provide an example route and i can try to find an explaination.
Kind regards
Martin

I think you’ve got a point with maxspeeds. I didn’t even think to add those tags. :)
