Improve itinerary description #9

Open perliedman opened 10 years ago

perliedman commented 10 years ago

The text description of a route is sometimes hard to follow, and not very detailed. Look into what can be improved.

See for example: https://github.com/perliedman/leaflet-routing-machine/issues/6#issuecomment-38325060

Any progress on this ? I get not only undetailed but sometimes empty instructions, which look awful in the UI (it result in a empty list item).

perliedman commented 9 years ago

@moimael wow! Do you have an example (waypoint coords or similar) where this happens?

Just try to route from Paris to lille for example. It happens almost on every route I try.

@moimael the frontend is not really to blame here. The main problems are:

OSM has a lot of short unnamed streets (the 1s, 8s and 3s intervals)
The instruction generation on the OSRM backend is pretty basic.

There is some code in OSRM to generate better turn instructions, but currently it is too slow to be used in production:

@TheMarex good to know. Do you know a relevant issue for OSRM-backend we could l link to here? https://github.com/Project-OSRM/osrm-backend/issues/685 seems like it could be related.

moimael commented 9 years ago

@TheMarex Thanks for the explaination ! Do you have any pointer to speed up OSRM code ?

TheMarex commented 9 years ago

@moimael to be honest its not a really priority at the moment. If you would like to take a step yourself, we are always happy to help new contributors.
