Can someone explain this routing problem?

Skrivet av NE2 den 1 oktober 2012 på English.

http://map.project-osrm.org/1r9 The obvious route is to follow I-80 all the way. But instead it gets off and follows surface roads across Indiana.

Could it be avoiding barrier=toll_booth? The exit where it gets off (SR 66) is missing this. But why would it avoid toll roads without the user telling it to do so, and why wouldn’t it be using the toll=* tag on the ways?

Looks like it’s fixed now.

Yep, it’s fixed. I don’t see any recent edits along I-80 here, so the OSRM guys may have changed something.

This is a very interesting development and it works! I tested it from Bonn, Germany to Croydon, England. It is very usable! What I noticed is that the were a number of purple overlays which seem to indicate that a OSM data error hinders the correct routing.

Is this so?

Should I, as a contributor, try to correct these “errors”?

Where are you seeing purple overlays? The only purple I see is the admin boundaries and the alternate route when you hover over the B at the top right of the route description: http://osrm.at/1sb

To NE2

I recalculated the route once again just now. No purple overlays. Unfortunately I did not take a snapshot of these purple overlays yesterday. It is just like your original post. NE2 registered something odd, iandees check and found nothing. Very strange indeed.

Anyway it is a very good tool and it should be accessible from the OSM Home Page, don’t you think?

You need to check the “small components” checkbox (where you choose the map) to see the purple overlays.

Huh? Whatever these ‘small components’ are supposed to be, they’re certainly not clustered around the routing.
