Hi, I am interested in comparing cost of different available paths for one vehicle. Currently, my approach is to compute the cost of one path as the sum of the edge cost over the edges that are used by the path. However, I have seen a important difference between the cost of one path and the sum of the edge cost over the edges that are used by the path. Also edge cost are defined using averaging over vehicles that travel along the edge given a time interval. I have seen the size of the time interval used impacts the edge cost. On the other hand, path cost can be given by "probe vehicle".
I was thinking about comparing path cost of different available paths by sending probe vehicle on each path and getting the experienced path cost of the vehicles. However, this approach will increase the total number of cars in the network and therefore change the traffic condition. I wonder if there is a way to send "ghost probe vehicle" on each path; meaning vehicle that have no impact on traffic (and could be crossed over by "real vehicle") . Is this possible? Is there a notion of "ghost probe vehicle" inside SUMO? If no, is there any tips to get could path-based statistics without edge-based statistics? Thank you a lot! -- Sent from: http://sumo-user-mailing-list.90755.n8.nabble.com/ _______________________________________________ sumo-user mailing list [email protected] To unsubscribe from this list, visit https://www.eclipse.org/mailman/listinfo/sumo-user
