Our self-developed road surface sensors to observe snow depth as well as weather sensors to monitor freezing condition of road surface during the winter season are essential technologies not only for snow removal on the road but for rationalizing operations to prevent road surface freezing. These two types of sensors enable not only energy-saving control of snow melting system but providing the drivers with road information in real time on snowfall and/or freeze on road surface to call their attention. Besides these technologies, we developed on-vehicle sensors to measure the salinity of anti-freezing agent spread on the road surface, contributing to preventing freeze on the road.

当社開発による、路面の凍結状態を監視する冬季気象センサーと、積雪状態を観測する路面センサーは、道路の除雪や凍結防止作業の合理化に欠かせない技術です。この両センサーにより、融雪装置の省エネ制御や、路面の積雪・凍結などの危険情報をリアルタイムで提供することが可能となっています。また、路面凍結防止剤の残留濃度を測定する車載式センサーを提供し、道路の凍結防止に貢献しています。
