发明名称 System and method for configuring a traffic control sensor system
摘要 A traffic control sensor system which provides outputted signals to a receiving traffic control system to assist the traffic control system in making real-time informed green light decisions. Such signals received by the traffic control system include calls for a green light for monitored traffic lanes approaching an intersection. The traffic control sensor system employs various techniques to reduce the number of vehicles that are dropped or occluded. A vehicle is considered to be dropped or occluded whenever the traffic control sensor system first detects the vehicle entering a user defined zone within the approaching lanes to the intersection, and then fails to detect or monitor such vehicle exiting the user defined zones. Occlusion or dropping may occur whenever a sensor is malfunctioning, certain environmental conditions are present, or during any time the sensor's detection signal is interrupted such as from cross traffic entering the monitored intersection.

主权项 1. A computerized system that includes at least one sensor for detecting targets upon a roadway surface, a method for creating a system configuration, the method comprising: an act of acquiring sensor data from at least one transducer view of a roadway surface which carries moveable objects; an act of detecting at least one of said movable objects within the one or more transducer views of the roadway surface; an act of establishing one or more virtual user defined zone upon the roadway surface within a detection area of said one or more transducers; an act of creating parameters which process data from the at least one transducer; an act of transmitting one or more green light requests after said processing to a traffic control system based upon the position of said at least one movable object in relation to said one or more virtual user defined zone; wherein the act of creating parameters which process data from at least one transducer comprises the act of establishing an occlusion zone protection timer which is activated upon the last detected stopped movable object being present within the one or more virtual user defined zone after said stopped movable object has been occluded.
