Greg at Metblogs.com pointed out a very nice traffic map of the twin cities that uses google maps. It has over 200 points where traffic is tracked. At each point you can get a speed estimate that lets you know of slow downs. You can turn on traffic cameras and get live up-to-date images of the traffic. Auto accidents and traffic construction alerts can also be displayed.
I have tried in the past to use live traffic data before I leave for work, but by the time I get on the freeway conditions have changed. When this live data can be pumped into your car via gps then it will really have a benefit. Regardless this is a great exercise in using the Google Maps API, and I can see this site getting some good advertising revenue in the future.
I probably won’t get much use out of this site, as my commute is all of 50 feet on a bad day.
