Re: [sumo-user] Why are vehicles stopping at a junction

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Deadlocks may be caused by network modelling errors but can also indicate problems with the behavioral models.

To better understand the cause of stopping, see https://sumo.dlr.de/wiki/SUMO-GUI#Investigation_Stopping_At_Intersections

Generally, it helps to updated to the latest sumo release.

If the problem shows up in the latest release, please provide a minimal example scenario for reproducing the problematic situation.

regards,

Jakob

Hi,

We are using sumo for a project and have run into some issue we can't explain. After running our simulation project for some time it goes into grid lock. And we have been able to trace (visually) the grid lock to the fact that some vehicle always stop at an intersection and do not move again even though there are not blockages or traffic jams ahead of it. This always happens at a particular intersection and at a particular time.

Wondering if someone has encountered such a problem before and what might be the likely cause and potential solutions? Also, is there a way to get sumo to generate an output on vehicles with information on why a vehicle can't proceed? Because visually it does seem that there is no reason why the vehicle should stop.

Thanks
