System and method for determining traffic conditions
First Claim
1. A method for directing traffic between selected routes using a wireless device, said method comprising:
- providing a plurality of wireless signal devices in vehicles traveling over a selected route;
generating a location signals from said wireless signal devices;
establishing a network of wireless signal receivers for receiving said location signals;
receiving said location signals from said plurality of wireless signal devices at said network of wireless signal receivers;
correlating the location signals for each of said wireless signal devices to said selected route;
resolving the velocity of each of said vehicles on a real time continuous basis from said location signals;
establishing a traffic profile associated with the selected route based on the location signals and resolved velocity of said vehicles; and
optimizing utilization of said selected route by directing said vehicles based on said traffic profile.

Abstract
The present invention provides a method and apparatus for determining traffic conditions using wireless devices. A number of signals from the vehicles traveling in selected routes are received by several wireless communication networks via the wireless devices. The total number of signals received are used to compare if there are sufficient number of vehicles traveling on the selected routes. If so, then the location information of the moving vehicles at various times is determined by the wireless communication network and forwarded to a central computer. The central computer coordinates with the wireless communications network for information needed to compute traffic data. The central computer computes the velocity of the moving vehicles and a traffic profile is created based on the velocity and location information of the moving vehicles. Furthermore, the traffic profile is sent to the moving vehicles.
