As far as I can tell, there is no way to utilize the route API to give me traffic estimates. For example, I want to know drive time at 5:15 PM on an average Monday or 2:00 AM on an average Friday. Passing useTraffic = true and other appropriate parameters, there is no change in output of drivetime. I've tried configuring the call every which way (and I've confirmed that the API response has all my input parameters).
The only thing that has an effect on route/time is use of timeType = 1. If I use this, then drive time will display for current traffic. Oddly, it will be slightly different from the realTime output.
Am I to understand that Mapquest will only attempt to calculate things like HOV lanes and road closures? If so, I can't say I'm not dissapointed...
