Re: [sumo-user] Why vehicle starts to blink when in an opposite lane?

[Rafael de Lima <rafalima123@xxxxxxxxx>]

Hi Jakob, thanks for the answer.

I attached a set of SUMO configuration files. In order to run, you just need to unzip them and execute the config file "/map/map.frontal-collision.sumocfg". When the simulation time reaches around 100 seconds, some vehicles will start to "blink/twinkle/become transparent". I think I agree with you that this problem seems to be related to graphics. I increased the step length from 0.01 to 0.03 and the issue decreased the frequency, but I would like to know if you can reproduce the same behavior on your machine as well.

Thank you very much,

Rafael

This is either an issue with your graphics driver or a bug in SUMO which was not reported before. Please provide the input files for reproducing the issue.

Hello guys,

I am trying to make a vehicle to collide with another in the opposite lane. I already got it by setting neigh attribute on net.xml file and added a parameter lcOpposite with high value on the vType attribute. Everything seems ok but the collider vehicle have a strange UI behavior. It is kind of blink or going transparent only when in the opposite lane.

1) Do you know why this happen?
2) Is there any way to disable this vehicle color behavior (blink/twinkle/become transparent)? In other words, keep the vehicle with normal color.

Thanks,

Rafael
