Hi, I was hoping to use historical traffic data and network analyst to determine what the cost (time, miles, etc) of obstructions. In essence, I want to see how blocking a bridge or a road in a network will affect miles and hours traveled.
Does anyone have any experience with this problem?
One way to solve this is to first have a set of routes that you want measure (i.e., start and end stops). Solve that route. Write out the results. Then place a barrier on the bridge and solve it again. Write out the results and compare.
You can use one route layer and load in multiple start/end stop pairs based on a conman ROUTENAME property. That way you only need to solve the route layer once and get many sets of routes solved in it.
