I have ben tasked with an assignment to plan a evacuation route out of a neighborhood that has only 2 exit points. I am trying to make a map that will code a series of streets by the number of turns an evacuee will have to make to get to one of the 2 designated exits. I have made this map by hand for a small neighborhood but now I have to do it for a much larger street network. I don't know if there is a way to get NetWork Analyst to count turns. I can't use nodes because it will include the end of the streets and intersections don't work because going straight is an option. I think closest facility is the way to go but I don't don't know enough about this extension to continue. Any thoughts?
