The Application of Visible Image Road Surface Sensors to Winter Road Management

Accurate grasp of road surface conditions is essential to winter road surface management. Road administrator is monitoring the conditions by road patrols and partly by using closed circuit television (CCTV) cameras and sensors. However, continuous monitoring with CCTV cameras is hard from the perspective of workload, and low judgment performance. The visible image road surface sensor developed by the Advanced Cruise-Assist Highway System Research Association (AHSRA) and the National Institute for Land and Infrastructure Management therefore has considerable potential for use in road surface management, enabling both the effective utilization of existing infrastructure such as CCTV cameras and the detailed monitoring of road surface conditions. Early detection of road surface freezing and refreezing after the application of freeze inhibitors are extremely important in preventing road surface from being frozen. The authors therefore introduced methods of using visible image road surface sensors to enable early detection of these phenomena.
