The Michigan Department of Transportation in the US has selected Navteq to provide real-time traffic information for a 2,000-mile road network in the state.

The system will inform drivers about real-time road conditions such as construction, traffic flow, and incidents and accidents, to help them decide alternative travelling routes.

The drivers will be able to access information from the department’s online traffic map as well as from electronic message boards along roads and overpasses.

The system uses the company’s smart traffic processor, which merges and optimises multiple sources of traffic data including GPS probe data, fixed sensor data points from toll tag readers, and proprietary and government sensors.

The $1.1m contract will cover a period of five years.
