Hello SUMO community,
I'm simulating a three lane highway but all the cars go to the leftmost lane, causing a huge jam. While searching for the reasons that may explain this behavior I encountered the "Proceedings of the SUMO2014 modeling mobility with open data" (http://sumo.dlr.de/2014/Proceeding_SUMO2014_15+16May2014_Berlin-Adlershof.pdf) from which I could start understanding the lane changing model implemented by SUMO. Every vehicle wants to have the highest speed possible (safest speed) for a given edge and that causes them to choose the leftmost lane (all of my vehicles top speed is much higher than the lane limit) for obvious reasons. They tend to stay in that lane until they approach their exit from the net, at which point they move to the right and leave. The problem that I have is that because SUMO doesn't allow vehicles to overtake on the right by law, if a car is stuck in the leftmost lane, it cannot move to the right lane even if its empty. Version 0.21.0 of SUMO has the option to allow overtaking on the right with the command "lanechange.overtake-right value="true" ", but the simulation is still acting up. I'm putting the command in the .cfg file as follows: <processing> <lanechange.overtake-right value="true"/> </processing> While it doesn't gives me any errors when I execute the GUI, vehicles are still waiting on a lane fully occupied instead of changing to an empty one. -Is this the correct method for putting this command?-How can I change other lane changing model's parameters? From the cfg file? -Is there another way to solve this lane preference? Thank you for your help and patience.
