Re: [sumo-user] Using Dijkstra

Thanks Michael

Is this for shortest route using distance or it can be used to find the fastest path as well? To use this function, I need to path edge object of source an destination, while I just access the edge id which is an string. How can I access edge object using edge Id?
Thanks for you time and help.

Hi,
just for the record: There is also a Dijkstra implementation in
sumolib.net.Net.getShortestPath.

Best regards,
Michael
