Abstract: The routing system and method find efficient routings among destinations in a traffic network. A starting point and at least one destination point are identified in the traffic network. The identified points are ordered into at least one tour. Traffic conditions for the traffic network are forecast for a time period of interest, and for each tour, a routing is generated using the forecast traffic conditions. A routing system implementing the method described in a computer or Internet environment includes a database storing a representation of the traffic network. A computer program provides means for selecting a starting point and at least one destination point in the traffic network, means for ordering the points into at least one tour, means for forecasting traffic conditions for the roads in the traffic network, and means for generating a routing for each tour using based on the forecast traffic conditions.
