COLLISION-AVOIDANCE SYSTEM AND METHOD

A method and apparatus for avoiding collisions of moving vehicles uses a position and motion locating system to track vehicle location and motion within a preconfigured operational zone. Each of a plurality of operational vehicles has a positioning device that communicates with a server to track the location and movement of each vehicle. The collision-avoidance system receives information on the position of each vehicle and determines a predicted trajectory for each vehicle. Based upon the predicted trajectories, the system predicts potential collisions by determining areas of intersection of a vehicle with other vehicles or stationary objects. When a collision is predicted, instructions are transmitted to units within each vehicle within an area of intersection to provide a collision warning to the vehicle operator and/or to control the vehicle speed in order to prevent the predicted collision.
