[sumo-user] Abnormal blocking in an intersection with traffic light

Hi all, I've been working on SUMO to simulate impacts of traffic light algorithms on network output, while I have observed a abnormal phenomena. A vehicle is half entered in the intersection and all other vehicles are somehow stopped before the traffic light, even the light is green. This phenome

Re: [sumo-user] Abnormal blocking in an intersection with traffic light

Hello, - which version of sumo are you using? Version, older than the latest release are known to contain bugs where vehicles sometimes block the intersection. If you are using an older version please upgrade and check whether your problem goes away. - if you are using the latest version of sumo, I

Re: [sumo-user] Abnormal blocking in an intersection with traffic light

Hi, Thank you very much for your feedback. I'm using sumo.0.19.0 for now. I tested with 0.20.0 and it still occurs. I investigate a little more and find that with fixed cycle fixed time traffic light, it seems to be OK. However we are testing an algorithm to update traffic light time and even

Re: [sumo-user] Abnormal blocking in an intersection with traffic light

Hi Jakob, all, We have investigated in detail and I think that we have found the small bug. If we watch carefully the video starting from 0:40. We see that there is a vehicle generated in lane 2 of west side of the intersection. The reason that the vehicle is generated here is in log as follows

[sumo-user] Simulation of vehicles changing lanes frequently

Hello everyone, I am working on a project about traffic simulation with SUMO. Now, I got stuck when I try to simulate a single car that changes frequently its lane. I think it might be possible to implement by configuring the route XML files. But it seems that I can only control the edge-changi

Re: [sumo-user] Simulation of vehicles changing lanes frequently

Hello, you can use TraCI to fully control the lane-changing behavior of all vehicles. see http://sumo-sim.org/wiki/TraCI http://sumo-sim.org/wiki/Tutorials/TraCI4Traffic_Lights http://sumo-sim.org/wiki/TraCI/Change_Vehicle_State regards, Jakob 2014-04-07 17:05 GMT+02:00 Thierry : > Hello everyon

[sumo-user] Losing cars on route generation/ Priority lane

Hello all, I have converted a big OD matrix to SUMO format and further generated the trips using the converted matrix and the districts file. I noticed that around 5.500 cars (out of 181500) are lost, part of them due to the use of internal lanes. What other reasons could it be? Another question:

Re: [sumo-user] Losing cars on route generation/ Priority lane

Hello, what do you mean by cars getting lost? There are only three legitimate reasons for cars not showing up in the simulation: - use of the option --scale - use of the option --max-depart-delay - use of the option --end so that the simulation finishes before all cars can be inserted If none of th
