I have a situation where vehicles on the minor road have a stop sign but, if there are no vehicles coming on the major road, these vehicles do not come to a complete stop (in SimTraffic). While it is true that both the minor road and the major road have very low volumes, there is a sight-distance issue that makes it impossible for the minor-road vehicles to safely proceed into the intersection without first coming to a complete stop at the stop bar.

Without having to do a network-wide change in driver characteristics, What can I do to code this so that the minor-road left turns actually come to a complete stop at the stop sign instead of just "coasting" through the intersection? By the way, I have already tried lowering the turning speeds but that did not work.

Thanks!

Hi Andy,

SimTraffic will allow this to happen based on:

"A vehicle approaching a stop sign can not be approved when it is within 3 ft (0.9 m) of the stop bar, .The stopping vehicle will be prepared to stop and at 5 ft may be traveling at 6 ft/s (1.8 m/s). SimTraffic assumes "Hollywood" type stops. A vehicle will slow to 6ft/s (4mph) but not stop, when there is no conflicting traffic. When there is conflicting traffic, both stopping and yielding vehicles will stop and wait."

You might try to change the gap acceptance factor. This would still not work if there are no main street vehicles. Otherwise, there really is not other way to turn this type of behavior off.
