Abstract
A navigation device has a GPRS receiver for receiving real-time information about slow traffic flow or slow average speed on a stretch of motorway, indicating congestion. The device calculates a new itinerary to avoid the congestion, based on historically recorded speeds on secondary roads weighed by the current average speed in the congestion area.
