I'd like to create a bus routable network with 2 different travel time as different bus speed design.
Option1: create Minute_speed1 and Minute_speed2 fields and calculate values. Then set TYPE as FIELD in evaluators
Option2: my though is: choose evaluator type as VB Script, then change the speed value inside Script Evaluator window. Is it possible to do it this way? If yes, how do I set up inside Script Evaluator? as i used the same calculation expression on option1, then found out they're different..:-)
