Re: [sumo-user] Collision detection at intersections
|
Hello,
collision checking relies on right-of-way rules to determine potential
accidents. It will not work with junction type "unregulated".
To force an accident, see
http://sumo.dlr.de/wiki/Simulation/Safety#Deliberately_causing_collisions
In the latest development version you can also set vehicle model parameters
for violating a red light:

Jakob
