[sumo-user] Issues with Vehicles in Simulation

Elliot W
Hi all,

When I run the simulation, the vehicles do not use all the lanes available, as shown.
I'm currently generating individual Vehicles in my rou.xml file, similar to the TraCI tutorial (not using Flows). 
I've tried adding a vType with [lcStrategic="100" lcKeepRight="100" lcSpeedGain="100" lcCooperative="1" lcSublane = "100"], and setting all the generated vehicles to be of that type, but to no luck.
I've also had vehicles stopping in the middle of intersections, which I would like to avoid. 

Please let me know how I can resolve these issues.

TIA

Hi,

 

sorry for the delay in response.

 

·        Regarding the lane problem, have you checked the vehicle routes and the connections at the junction in the picture you send and at the next junction? In this picture you can see an example of what I mean.

If you have a net like that and your vehicles want to go from edge gneE0 to gneE3, they will use only the middle lane on the edge gneE0, because if they take the right lane, then on the edge gneE1 they will not be able to go straight, they can only turn right towards edge gneE5. I hope this is understandable.

 

·         I don’t understand this error, could you explain it a bit more?  Are they stopping because of congestion? “I've also had vehicles stopping in the middle of intersections, which I would like to avoid.”

 

Regards,

Giuliana

Also, try setting a value < 1 for lcStrategic. This will reduce the foresight distance that affects strategic lane choice as explained by Giuliana.
