摘要： A sheet-shaped magnetic marker to be laid on a road surface so as to be able to be detected by a magnetic sensor attached to a vehicle to achieve assist for driving operation of the vehicle by a driver or control on a vehicle side to achieve automatic driving independently from operation of the driver has a magnet sheet (11) as a magnetism generation source and a wireless tag (2) which outputs information via wireless communication to the vehicle side. In the magnetic marker, the wireless tag (2) is interposed between a sheet (11A) and a sheet (11B) configuring the magnet sheet (11), and the entire wireless tag (2) is accommodated inside the magnet sheet (11).

摘要： A traffic light control assembly includes a plurality of mounting poles each attached to a cross beam of a respective traffic signal at a roadway intersection. A plurality of light detection and ranging sensors is each mounted to a respective mounting pole to be elevated over traffic on the roadway. Each of the light detection and ranging sensors is positioned to sense the number of vehicles that are stopped at an opposing traffic signal. Each of the light detection and ranging sensors is in electrical communication with a remote data unit thereby facilitating the remote data unit to analyze data gathered by each of the light detection and ranging sensors with respect to the number of vehicles. Moreover, the remote data unit adjusts timing of the traffic signals to most efficiently direct traffic through the intersection with respect to the number of vehicles that are approaching the intersection.

摘要： A sheet-shaped magnetic marker (1) to be laid on a road surface so as to be able to be detected by a magnetic sensor attached to a vehicle to achieve assist for driving operation of the vehicle by a driver or control on a vehicle side to achieve automatic driving independently from operation of the driver is divided into a plurality of regions in a matrix shape by a cut line (1C) cutting a magnet sheet (11) and a nonskid layer (181), with an adhesive layer being left. Thus, if peeling partially occurs, a region including the peeled part can be isolated, and expansion of peeling can be prevented.

摘要： A system and method for collecting, processing, storing, or transmitting traffic data. A localized data collection module may retrieve, receive, or intercept traffic data through or from hardware installed in a traffic control cabinet adjacent an intersection or other roadway feature of interest. Data which may have previously been confined to a closed loop traffic control system may be remotely accessible for traffic operations control or monitoring via a network connected server and/or cloud architecture.

摘要： A three-mode geomagnetic detector is provided. The detector includes an upper cover, a lower casing, and an inner container. A bottom of the inner container is detachably connected to a bottom of the upper cover, the inner container is sleeved within the upper cover, and the upper cover is snap-fitted to the lower casing. Through the design of the inner container, the use of an O-shaped sealing ring is avoided, such that poor sealing caused by the O-shaped sealing ring deformation due to vehicle rolling is avoided, and opening for replacement of components is convenient.

摘要： In a marker detection method in which a sensor unit (11) that includes a plurality of magnetic sensors arranged in a vehicle width direction is used to detect magnetic markers (10) laid in a road, a feature value that represent symmetry of magnetic distribution, which is the distribution of magnetic measurement values obtained by each magnetic sensor included in the sensor unit (11) is generated, and threshold process regarding the feature value is executed to determine the possibility of the presence of magnetic generation source other than magnetic marker (10), that causes disturbance, and hence to suppress erroneous detection.
