I have created a network for determinging pedestrian travel time over a rural set of roads. I have classified the roads based on condition, I would like to use these road classes in my travel time cost attribute. Example: If road type is 1,2, or 3 then speed calculation should be Length of road * 60(minutes)/5500(meters) If road type is 4,5 or 6 then speed calculation should be Length of road * 60(minutes)/3500 (meters)
How to I create this into one network attribute evaluator? Any help or advice would be appreciated.
