I've never looked at commute time data before, so I'm just an armchair analyst.
It seems to me though, as a driver, that commute times are dominated by accidents. And certainly while you could estimate the mean probability of an accident based on the number of travelers, the daily variance seems insanely high and its unlikely that any amount of training data is going to decrease that much. I wonder how good these results are going to be.

- dkokelley 16y agoWhile the estimates for < 1 hour might be thrown off by an accident, you could get fairly accurate 1+ hour traffic accounting for accident probabilities, and the time it takes for them to disperse.
- brc 16y agoI would assume they want to build a realtime system and can feed in accidents to change the prediction time for a web/mobile application and/or electronic boards on the motorway. So in that case, you'd have to be able to input an accident at place x and have that reflect in the projected times.
