Thank you Jakob. Actually, I wanted to solve two issues by finding n fastest routes. 1) reroute traffic in a stochastic manner to a number of alternative routes instead of only the best route. The gaol is to avoid inducing too much traffic on the fastest route. In my experiment if I have more than 20% cars with navigation device the rerouting makes the congestion worse. 2) I wanted to measure the redundancy in the network by finding all possible paths for OD pairs. Any hints for these two?

Also, the n-fastest routes in a strict mathmatical sense are often not useful because they include minor variations on the fastest route (high overlap) rather than real alternatives (low overlap). The marouter application can compute a set of route alternatives using the penalty-method (found paths are penalized to encourage alternative routes without overlap). This algorithm can also be reproduced via TraCI by dynamically adapting the edge traveltimes before calling findRoute. regards, Jakob Am Do., 11.
