    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： The present invention extends to methods, systems, and computer program products for detecting targets in roadway intersections. Transmit antennas transmit signals into a roadway intersection. Receive antennas receive corresponding signal reflections off objects in the roadway. The reflections correspond to two dimensional image data for the roadway intersection. The reflections are conditioned for compatibility with a processor. The processor processes the condition reflections into a two dimensional image of targets in the roadway intersection.
