Hello, I would like to write a diploma thesis about routing in consideration of the traffic flow. For this i thought to use openstreetmap as the database for the geographical information.
In a nutshell: I will create a database which contains "realistic" speed informations for way sections of openstreetmap. With way sections i mean drivable connections between "parting of the ways"-nodes. For this i will analyse gps-tracks to calculate the average time the persons need from one parting node to another dependent of the time of day. For example: there is a person who needs 30 min from node A to node B at 17 o'clock. Another person needs for the same distance 20 min at 17:20. In the routing program i will start to travel at 16 o'clock so the routing software calculates that i reach the lane A-B at 17:10. Now the routing software interpolates the time costs from 17:00 and 17:20 and get a time cost about 25 min. This "realistic" speed informations will hold in the database and could used with openstreetmap for routing. I would like to hear some opinions of the experts here - what do you think? Is this useful or to imprecise, or does such a database already exists? Thanks and greetings, Stefan _______________________________________________ Routing mailing list Routing@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/routing
