DEVELOPMENT OF THE ROAD SURFACE OBSERVATION SYSTEM
The paper describes how the proposed road surface observation system consists of two types of sensors, a buried sensor and a laser sensor, which are used to detect the condition of the road surface. By using the advantages of two different detection methods, the system has proven to be perfectly able to identify divers road conditions, such as dry, wet, frozen and snow covered, for a broad area of the road surface. Adding a unique concentration-of-salinity detection function will enable the system to predict the freezing point of surface water, an advantage that advances the system as a strong candidate for use in road-management systems.
