I created a network database where each arc has three time fields. Time from one direction, from the other direction and then the worse of the two.
My original plan was using the third field when creating service areas. But then I realized it doesn't work, because I'm just assuming for each arc the worst time where I should be assuming the worst time for the sum of the arcs in each direction.
In your opinion what is the best way of combining away from and towards facility service areas?
What I'll try to do now is just intercepting away from and towards service areas for each break, but this just doesn't feel *right*.
