hi. i am trying to solve the route. i have network dataset with the attributes for restriction. the route is supposed to avoid traffic lights. The problem is that it does the shortest route by default but completely ignores the restriction. If i load this layer into network analyst as a barrier - it does not see it again. I tried to make search tolerance as small as possible as well as snapping all feature classes participating... what could be the problem? could someone help me please?
