Re: [sumo-user] Different seed values affect vehicles freezing in junction

Okay. Thank you for your reply. I will change all the intersecting lanes in the junction. 

If there continue to persist any further problems after the change, I will let you know.

Thank you,
Knight H.

Hello,
at some of your intersections every incoming lane is connected to every straight outgoing lane. This is generally not recommended and is responsible for the observed problems. Please make sure that the car connections from one edge which is given the green light, do not cross each other. (only one straight connection from each lane all going in parallel).

regards,
Jakob

Hello, 

I have a problem when I use different seeds, the vehicles freeze at different junctions (some seeds also make the vehicle flow without any freeze). 

This photo is when I use --seed 0, where the vehicles freeze at the right junction.

This photo is when I use --seed 100, where the vehicles freeze at the left junction.

However, there was no freezing problem when I use --seed 10. 

The seed values used to cause this behavior is done through pure trial and error, since I have yet to know the root cause of the problem. 

I am using SUMO v 1.1.0 built on Ubuntu 18.04 using cmake. 

I have included the net-file, route-file, gui-settings, add-file, and configuration file in an attempt to let others reproduce the problem in the tar.xz included. In Linux it should be just a simple:
./runner_bug_seed0                  # to see the seed 0 case (freeze right)
./runner_bug_seed10_nobug    # to see the seed 10 case (no bug)
./runner_bug_seed100              # to see the seed 100 case (freeze left)

I am not sure if the bug will be present and exactly the same for everyone but this is what I am currently facing. Does anyone have any ideas why this is happening?

Thank you,
Knight H.
