Question

I use two Connectors (one for each Lane) when coming from a double-lane Link to a single-lane Link. How can I avoid unneccesary lane change due to the fact that there are two possible routes?

Answer

This way of modeling is incorrect. You only need to have one Connector linking the double-lane link with the single-lane link. Because of the route functionality of PTV Vissim, vehicles automatically will change lanes to the one which is connected to the single-lane Link - and thus there is only one possible route.

This kind of modeling is recommended both for static routes and Dynamic Assignment.
