I would like to write a diploma thesis about routing in consideration of the traffic density.
For this i thought to use openstreetmap as the database for the geographical information and as the database to analyse the
In a nutshell: I will analyse the diffenent gps-tracks between nodes to calculate the average time the persons
need from one node to the other 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.
Now i have two questions about openstreetmap, and i hope anybody can anwer this:
Though the api it’s possible to get all the gps-tracks for a region. The tracks contains lon and lat, but no
time information when the trackpoints were generated from the gps-receiver. I need the time information to
calculate the time costs, is it possible to get them in some way?
In openstreetmap will the gps-tracks be stored permanently, or will they removed when the region is complete mapped and there is no
more use for them?
Thank’s for help
