Re: [sumo-user] Frontal collisions never stops to warning
- In many cases, the vehicles do clear up their positions eventually even after a frontal collision
- In the latest development version there is only a single warning for each distinct collision event even if the situation persists for multiple steps
- collision.action="" is intended mostly as a debugging tool.  The most "realistic" treatment of accidents is  --collision.stoptime FLOAT combined with --collsion.action 'remove' or 'teleport'

Jakob

Hi Jacob,

Thank you very much. Seems that is a SUMO limitation by not solving Frontal collisions as it solve other kind of collisions (eg: rear end, junction or collision). So I will have to use some TraCI code to force vehicles to change their positions in order to "stop" the warnings at least until SUMO remove the vehicles. 

Thank you gain,

Your configuration sets --collision.action warn
This means only a warning is given and no other action is taken to resolve the collision. This is usually not a problem for rear-end or junction collisions since the vehicles continue moving and take up their preferred distances later on. Frontal collisions do not resolve themselves this easily.
Alternative actions are 'teleport' and 'remove'.

regards,
Jakob

Hi guys,

I configured my SUMO execution to have some frontal collisions on the opposite lane. To achieve that I used neigh attribute on net.xml file and added parameter lcOpposite on a vType attribute. Everything seems ok and the collisions are happening. But when some collisions occur SUMO does not stop to warn about that collision. For instance, this warning is being showed a lot of times and will never stop:

Is there any way to avoid this behavior without move/remove vehicles with TraCI?
