i always thought synchro/simtraffic always keep the cars off the intersection in congested intersection. so dont block the driveway/box/intersection is always implemented. people wait before the stop sign, not in the section. looks like it is not. my cars are going through a car waiting at an intersection. like southbound left turing cars are going through a northbound car waiting at the intersection

Hi Jahid,

Version 6 does have gridlock avoidance logic. That is, vehicles are not allowed to enter the link until approved. This involves an algorithm that tests to see if the intersection will be cleared and then that they can clear.

In some instances, a vehicle may bet approved, but due to some unforseen event downstream, they may hang out slightly in the intersection. It may look like vehicles are passing through each other, but it's not a real collision.

Thanks,

John.
