A thought popped into my head while I was reading another thread that was talking about several Workout/Runners' apps. This is half typical curiosity and half actual real world action. I'm wondering if there's an app out there that can track traffic patterns/route times. I know that those Runners apps. can track speed/time to destination, but I'm interested in being able to track which highways/roads have the most/least amounts of traffic on which days and at which times, or which roads cause you to wait the longest at certain lights, so that I can know in advance (the app. would alert me which route to take on which day according to data collected over time). I've always been kind of fascinated by traffic patterns, but I'm also a fairly focused driver, so I don't generally look at times it has taken me on different days. You can feel like taking a back way one day, but does it really save you any time with all the lights you hit instead? Anybody know of any app. out there like this?
