I have an application for routing oversize vehicles, and at certain intersections I need to restrict only certain turns based on parameters or conditions of the vehicle. For example, a vehicle over 80 feet long cannot make a left turn but all shorter vehicles can make the left turn. The 80 foot vehicle can however go straight through the intersection or make a right turn. Is there a way to place a turn restriction that checks the vehicle parameters?
Here are some resources with examples to help get you pointed in the right direction:
