[OSRM-talk] Travel duration not realistic

Hi,

When computing a route and its duration between two points in a big city, duration result is not realistic.
In Paris for example, a straight road of 1km takes less than 1 mn to be crossed.
Google maps, proposes 5 mn which is more close to reality values.

Beside taking into account real time traffic info, could you please help setting a solution to enhance those results ?

If I well understood, I have to try different values for tags like speed, maxspeed, penalties etc...
Is there anyone who already did some tests for this topic ?
Which tag to modify first, especially in the example I provided ?
Is there any influence for data, like roads attributes ? Example, maxspeed for motorways is set in the profile but some motorways have different speed.
So I wonder if OSM data includes such information and if osrm takes this into account.



Best Regards,

Richard
