Rear Surveillance System for Japan Highway Public Corporation

摘要

Maintenance work on highways is carried out using special types of maintenance vehicles. Although these vehicles are equipped with signboards to warn following traffic, accidents do occur due to rear-end collisions.P-MAC (Protection system of Maintenance vehicle Against Collision) is a rear surveillance system that is being developed by the Japan Highway Public Corporation. The purpose of P-MAC is to prevent any such traffic accidents as an additional measure to the large bumper and LED signboard that are presently employed. P-MAC consists of two CCD cameras and a millimeter-wave radar as a sensor. While these two devices have different features, the output data are integrated so that the advantages of each device can serve for practical detection of danger.This paper mainly describes the part of the P-MAC system developed by Toshiba.
