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).

A portable or affixed stop sign warning system which enforce stop sign violations through automated photo enforcement with the use of radar and camera technology and incase of any incidence record the event. The system includes a plurality of surface mounted RADAR, computer, camera and video camera which provide the stable, reliable and accurate information necessary, video monitoring, and incident detection. The multi-tracking radar tracks vehicle speed and position as it approaches the stop sign. The system will use the distance, speed over time, acceleration and retardation to capture and automatically validate a stop sign violation. The violation evidence includes but not limited to high-definition picture before the stop line, high-definition picture after the line, close up of the license plate, photos show the stop sign, time, date, speed, and location of incidence.

A magnetic marker (1) to be laid on a traveling road where a vehicle travels includes a circular sheet-shaped magnet sheet (10), which is a magnet as a magnetism generation source, having a diameter of 100 mm, and a reflective sheet (15) forming a reflecting part which retroreflects laser light from a lidar unit mounted on the vehicle and is laminated on a surface of magnet sheet (10). Since the magnetic marker is detectable not only magnetically by a magnetic sensor but also by a lidar unit using laser light, the magnetic marker is easily detected compared with a general magnetic marker that is detectable only magnetically.

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.

The invention relates to the guidance of autonomous vehicles and in particular, relates to guiding an autonomous vehicle along a roadway with active devices with a system which works during normal and inclement weather as well as under any luminous conditions. These active devices are embedded in the passive and/or active road details such as traffic signs, traffic lights, warning lights etc. These active devices provide data relating to road conditions, speed, road layout etc. as well as other information such as availability of parking spaces. Accordingly, through networks of sensors and devices the autonomous vehicle can obtain road details in real-time in severe weather conditions such as heavy snowstorm, ice, fog or other inclement weather.
