Startup Idea: Traffic Avoidance Mobile App

Startup idea to develop an application that alerts users about upcoming traffic jams, accidents, or bad weather conditions affecting traffic. The software should provide alternate route suggestions based on GPS, weather reports, and real-time traffic information.

I hate getting stuck in traffic. I would love to have an app that would warn me of upcoming traffic jams. Or accidents, or bad weather, such as freezing rain that slows down traffic. It should calculate an alternate route that's faster, such as using side streets. It should use GPS, weather reports, and traffic info.
