Navigation system and travel coordinator with dynamic traffic data
First Claim
1. A navigational system comprising:
- a central database including;
a central memory storing a plurality of current travel times corresponding to actual travel times for wireless communication devices traversing particular street segments which are stored at the central database by an application server;
a application server including;
a application server having an input for receiving and transmitting locations, computed data, and information to the central database and an output indicating a travel route from the starting and ending locations having a minimum travel time based upon the current travel times; and
a wireless network infrastructure and internet structure for delivering data on an individual travel route to each of a plurality of wireless communication devices from the application server; and
wherein each wireless communication devices is associated with a respective one of a plurality users and comprises;
an ability to determine its position either by GPS satellite signals or other triangulation methods and determining geolocation of the wireless communication device;
an ability to send and receive data visually and audibly from the application server;

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.
