Patent number: 10276041Abstract: The present invention extends to methods, systems, and computer program products for detecting targets across beams at roadway intersections. Embodiments of the invention include tracking a target across a plurality of beams of a multiple beam radar system in a roadway intersection and updating track files for targets within a roadway intersection. Returns from a plurality of radar beams monitoring a roadway intersection are divided into range bins. Identified energy in the range bins is used to compute the position of targets within a roadway intersection. When the position of a target is computed, it is determined if the position is a new position for an existing target or if the position is the position of a new target.Type: GrantFiled: March 22, 2018Date of Patent: April 30, 2019Assignee: Wavetronix LLCInventors: David V.

Patent number: 9412271Abstract: Methods, systems, and computer program products for optimizing automobile traffic flow through an intersection by detecting and reducing platoon interference. One method, performed in a computer product, includes steps of identifying a cluster in traffic information of a cycle of a traffic signal, determining that the cluster qualifies as an upstream platoon, calculating properties of the platoon, and generating an Enhanced Purdue Coordination Diagram (EPCD) for the cycle based on the calculated properties of the platoon. Another method includes obtaining, by a computer device, traffic information corresponding to an intersection; determining, by the computer device, platoon properties of the traffic information corresponding to each cycle of a traffic signal; and calculating, by the computer device, a timing change to make to the traffic signal to improve traffic flow through the intersection, the timing change being based on the platoon properties.Type: GrantFiled: January 30, 2013Date of Patent: August 9, 2016Assignee: Wavetronix LLCInventor: Anuj Sharma

Patent number: 7991542Abstract: The present invention extends to methods, systems, and computer program products for monitoring signalized traffic flow. A processor in a sensor system or traffic controller interface estimates the time-of-arrival and other traffic flow estimates of one or more vehicles to an intersection stop bar, while the vehicles are within a continuous range of one or more transducers view of the sensor system. A level of efficiency and safety within the signalized traffic flow is estimated by the sensor system based upon one or more of the estimated time-of-arrival and other flow variables estimates and then communicated to the control unit of the traffic signal system. Other flow estimates for each vehicle include but are not limited to: position relative to the stop bar, lane position, velocity, acceleration, time headway and classification.Type: GrantFiled: March 21, 2007Date of Patent: August 2, 2011Assignee: Wavetronix LLCInventors: Bradley C.

Patent number: 7924170Abstract: 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.Type: GrantFiled: August 24, 2009Date of Patent: April 12, 2011Assignee: Wavetronix LLCInventors: David V.

Patent number: 7573400Abstract: The present invention extends to configuring detection zones in a traffic monitoring system and to association of detection zones with corresponding traffic signal phases. One or more sensors detect targets within a roadway intersection. The sensors integrate acquired sensor data for the targets into track files. The track files are subsequently used to identify common target paths. A histogram is used to identify common target positions for stationary targets. From the common target positions and the common target paths detection zones are configured. Detection zones are associated with traffic signal phases so that specific detections can be created. Lane boundaries within the roadway intersection are inferred from the common target paths. Permanent stationary target locations are identified from the common target positions.Type: GrantFiled: October 31, 2005Date of Patent: August 11, 2009Assignee: Wavetronix, LLCInventors: David V.

Patent number: 7427930Abstract: A vehicle traffic sensor for detecting and monitoring vehicular targets is presented. The sensor employs a planar design resulting in a reduced profile sensor. The sensor includes a multi-layer radio frequency board with RF components on one of the sides and both isolation and planar array antennas on the opposing side. The antennas are preferably tapered planar array antennas which include one transmit antenna and one receive antenna. The sensor also includes at least one logic or signal processing board populated with components on a first side and a ground plane on a second side positioned toward the RF componentry of the RF board to form an RF shield. The boards are housed within a housing that is permeable, at least on the side through which the antenna structures propagate.Type: GrantFiled: December 23, 2003Date of Patent: September 23, 2008Assignee: Wavetronix LLCInventors: David V.

Patent number: 6556916Abstract: A method for dynamically defining traffic lanes in a traffic monitoring system is presented. A traffic system sensor detects vehicles passing within the field of view and process the data into an estimation of the position of each of the detected vehicles. The positions are defined and recorded for use in a probability density function estimation. The traffic lane positions are defined such that further detection of vehicles may be assigned to a particular traffic lane without requiring manual set-up and definition of the traffic lane boundaries. The traffic lane boundaries may change or migrate based upon modification of traffic paths due to construction, weather, lane re-assignments and the like.Type: GrantFiled: September 27, 2001Date of Patent: April 29, 2003Assignee: Wavetronix LLCInventors: Jonathan L.
