I use a non-overlapping drive time tool a lot in figuring out trade areas for our network of centers (including figuring out where to put new centers).
For some reason, the San Francisco/Bay Area are a sticking point in the non-overlapping DT tool. I can run all 70 of the other sites in a batch in a fraction of the time it takes to get a trade area output for the 3 sites in Bay Area.
Anyone have similar issues or know of a work around?
