[OSRM-talk] Comparing OSRM with the car routing by OpenTripPlanner

[Xavier Prudent]

Dear all,

I am comparing two routing machines: openTriplanner and OSRM on the OSM map
of Québec city (Canada) when looking for the best route by car.

I get very puzzling differences, just running the default versions and
configurations of OSRM and OTP for these coordinates:

origin
46.793187,-71.183014
destination
46.770641,-71.285499
at 8am, mode car.

The best route by OSRM is a 16km (18min) long, while the OTP recommandation
is a 20km (24min) one.
Google map recommends the 20km one (21min), the 16km road having a duration
of 25 min.

The 20km route goes along a highway, while the 16km one uses a primary
road, I don't get why OSRM thinks this road is faster, while OTP points the
opposite.

Are you able to reproduce this discrepancy? Does that make sense to you?

Thanks,

Xavier
