Abstract

Weigh-In-Motion (WIM) is a system, which is able to weigh a moving vehicle. The system is a part of Intelligent Transport System (ITS). The data obtained by this system can be used for many purposes in the road and railway system. Most of the WIM systems operate at a relative low speed. At high speed, the accuracy of the system reduces. Therefore, a new WIM system was developed so that the weighing can be performed at high speed with a better accuracy. Besides, the system was able to recognize the plate number of the overloaded vehicle, record its weight and snap its picture: for Mher law enforcement. This project utilized various weight sensors to detect the vehicle weight, investigated the response of the weight sensor to the axle force, developed a suitable algorithm to facilitate the vehicle weight measurement at high speed, created an interface to trigger the plate number recognition system from the WIM system and developed a database to record the results of the WIM system measurement and the captured violated vehicles. Loadcell and piezoelectric WIM systems including the weight estimation algorithm and vehicle plate number recognition system have been developed successllly in the course of this project. The load-cell WIM system which has been developed has a weighing capacity up to 20 tonnes and able to measure at the speed up to 60 km/h. The piezoelectric WIM system has been tested to weigh various types of vehicles. The system is able to weigh at high speed with 95% accuracy.
