Google Maps adds arterial traffic monitoring

Traffic monitoring has been available on Google Maps for some time, but has been limited to highways and major roads. According to the Google LatLong blog, traffic tracking support is now available for smaller surface roads in select cities. The data is gathered through mobile phones running My Location. Anybody wishing to help out can sign up their phone and opt into My Location to participate in the anonymous data collection. Now you won’t have to gamble on whether or not your back road alternative route is congested when there’s construction on the freeway. Dash tried something similar with their two-way traffic reporting, but we’re guessing that Google’s version will have even better performance thanks to a rapidly increasing install base.
