[Tagging] [Talk-us] stop signs

[john at jfeldredge.com]

The amount of delay varies according to the traffic, particularly in cases where one cross-street is not required to stop at the intersection.  I have encountered intersections where, at rush hour, you effectively can't make a left turn from the side street, or go straight across, because the traffic on the main road is continuous and the drivers don't choose to yield to the side-street traffic.

+1

Also, the number of seconds to add would vary drastically, sometimes
even within the same intersection.  I'd very much like to add a large
penalty for making a left turn at a particular intersection exiting my
development, but not add much of a penalty for making a left at a
different intersection, or making a right at either of them.
