Would it be possible to set a custom link speed from average link speed found using GPS data for a region. In Montreal area, we get GPS data from car sharing company and we can get real speed profiles for every hour of the day on almost each segment. How could we integrate this data into the routing engine so we can calculate real fastest path while in congestion by choosing the date and time before calculation?

Also, for bicycle, it would be great to be able to calculate a route using different weight than speed (like a weight calculated from altitudes gradients, presence of cycling paths, etc.) and still get the actual travel time. (I mean calculate the route using one weight different than length/speed and then calculate travel time on that route using length/speed).

If possible, we, at Polytechnique Montreal, are going to collaborate, since it would help us advance a great amount of projects related to mobility and route calculations.
