What I was visualizing was not so much real-time traffic mapping, but rather that certain roads are almost guaranteed to be uncrossable on foot at certain times of day, such as at rush hour. If you are trying to cross them at times when the traffic is light, it is possible to do so, with caution.

Curves can already be detected by routers (they are in the data), pedestrian crossing (with and without traffic lights) should be mapped explicitly (in the 1 road, 2 sidewalks model it would be a way from 1 sidewalk to the other). Realtime traffic information (time of day, amount of traffic) is a general issue that one day we might be able to solve, given enough real time data input. cheers, Martin -- John F.
