I'm having some issues to where the historic traffic data associated with the Routing_ND from StreetMap14.1 doesn't seem to be enabled.
Following the help section, I've checked to make sure my TravelTime (minutes) field has traffic enabled, which it does. I use the TravelTime (minutes) field as my Time Attribute, then set my specific day in Analysis Settings.
I'm routing a group of orders and setting their Start/End times between 3-7pm, and get the correct resulting routes.
To see if the historic traffic is being used, I changed my orders to 3-7am, and the associated Depot/Route times. My thinking was that the route times would be different taking into account the traffic density for those hours.
I'm still getting the same exact route times/distance traveled values, so I don't think traffic is being used, or is enabled.
