Detecting targets in roadway intersections |
摘要 |
The present invention extends to detecting targets in roadway intersections. A traffic sensor includes a transducer system and a transceiver system. The transducer system creates a plurality of transducer views for detecting targets located in a portion of the intersection. The transducer system includes a transducer configured to transmit signals towards and to receive signals and signal reflections within a portion of the two or more approaches to the intersection. The transducer is configured such that when necessary the transducer can transmit a signal and receive a signal or signal reflection simultaneously. The transceiver system is configured to generate digital data indicative of the transducer receiving a signal or signal reflection. The transducer system and transceiver system interoperate to generate an aggregate sensor view of the intersection that includes a plurality of transducer views of the two or more approaches to the intersection.
