Traffic congestion is a common problem in the automotive highway system. Dynamic conditions such as traffic load, road construction and accidents introduce problems for static route determination in travel planning. Many on-line mapping systems (such as MapQuest) provide the ability to obtain shortest or fastest path travel directions between locations, using static information. This disclosure extends road-based sensor networks to include GPS enabled automobiles (thereby supporting all roads, rather than just the cities/interstates with sensor networks) and to apply known flow/congestion control algorithms from computer networking to the traffic problem.
