Hi Jakob, thank you very much for your reply, now it worked perfectly fine.
Regarding leader vehicle, now the vehicle is been detected but only when it is in the same lane ID and when it is in different lane , it does not show any value although distance argument is satisfying. When the leader vehicle leaves the lane of ego vehicle, it disappears and sumo does not show any vehicle detected. How to solve this problem? I am hereby attaching screenshots of both the scenario (different lanes and same lanes). <http://sumo-user-mailing-list.90755.n8.nabble.com/file/t206/leader_different_lane.jpg> <http://sumo-user-mailing-list.90755.n8.nabble.com/file/t206/leader_same_lane.jpg> I want to detect the leader vehicle and get the position and velocity of that vehicle and then transfer it ti IPG traffic objects. Any information about this would be a great help for me. Thank you in advance. -- Sent from: http://sumo-user-mailing-list.90755.n8.nabble.com/ _______________________________________________ sumo-user mailing list firstname.lastname@example.org To change your delivery options, retrieve your password, or unsubscribe from this list, visit https://www.eclipse.org/mailman/listinfo/sumo-user
