I currently use ArcMAP 10.3 with StreetMap Premium 14.2. I am trying to implement historical traffic data into my routing solves, but i'm not seeing much of an impact.
For example, I had some runs in San Francisco. I used TravelTime(minutes) as my Time Attribute, it has traffic enabled. I had some deliveries at 3pm, these ran correctly and I got my results. To test whether traffic was being used, I changed all (routes, depots, orders) my corresponding times to 3am. The results returned the same travel time, although the roads went from red (Stop and Go) to green (Free Flow) between the two times. Is there a step i'm missing to active traffic data?
