Abstract: A system provides personalized traffic information and route planning capabilities to users of the system using existing wireless personal telephone and communication systems that allow for the geo-location of users in the network. This system uses standard geo-location methods and telecommunication equipment to triangulate the position of a user and transfer data between them and the central system. This user information is collected and used to compute real-time system wide model of the street segments in the traffic network. This model can then be used to create individual routing information for any user of the system. This computed travel time information is used to determine the most efficient route for a user and can be transmitted to the user. As a user travels, their location is constantly obtained and their travel route information is updated and relayed to them.
