THE CONTROL ON OVERLOADED VEHICLES AND AUTOMATIC AXLE WEIGHING SYSTEM FOR RAPID TRANSIT INSTALLED IN THE HANSHIN EXPRESSWAY

摘要

The Hanshin Expressway has a network in the Kansai urban area of Japan. With improving the efficiency of freight transportation systems and the size and weight of commerce vehicles, it is obviously increasing overloaded vehicles. Traffic accidents by overloaded vehicles should be prevented and the noise and vibration have to be reduced. There are two ways to detect overload vehicles. Police Force and Hanshin Expressway Co., Ltd. cooperate to stop vehicles and to measure vehicle static loads. In another way, Automatic Axle Weighing System at the toll gates is monitoring of axle loads of vehicles and shooting photos at the tool gates. The system defines overload vehicle, then a warning notice is forward to owner of the vehicle. Since ETC system installed to toll gates, vehicles are running through the toll gate in 30km/h speed limit. Then Hanshin Expressway Co., Ltd. installed “the High-Precision Automatic Axle Weighing System” to detect the axle load of running vehicles. However, this High-Precision Automatic Axle Weighing System costs very high. The idea of new Automatic Axle Weighing System is considered. It should be able to detect the axle load of running vehicles with lower cost than High-Precision Automatic Axle Weighing System.
