| Summary | How to use the latest technology to improve the operation performance of CVO is one of the key elements of the Intelligent Transportation System. In this study, the specifications of applying high-speed WIM on enforcement are firstly developed. In addition, the feasibility of integrating automatic vehicle identification (AVI) and WIM system is also studied. The major contents of this research are: (1)Evaluation of the operating performance of weigh stations: Interview, questionnaire survey and traffic flow study in selected weigh stations are applied to realize the operating performance of weigh stations on National and Provincial highways. (2)Development and field test of the specifications for applying high-speed WIM on enforcement: Based on the review of specifications operated worldwide the development of theoretical approach for accuracy requirement and the discussions in workshops, the specifications for applying high-speed WIM on enforcement were developed. Through the field test on Lung-Tan weighing station in national expressway no. 3, the developed specifications were verified. (3)Simulation of queuing process in weigh station: Utilize the traffic flow data, a simulation program is developed to simulate heavy vehicles* delay time in weigh station. (4)Development of the CVO cost model: This model consists of heavy vehicles* delay costs, WIM system capital and maintenance costs, AVI system capital and maintenance costs, pavement construction and maintenance costs and police salaries. This cost model is applied to calculate the total social costs between different alternatives. (5)Propose the feasible strategies of integrating the AVI and WIM systems: Based on the research findings from the above, two main recommendations to integrate AVI with WIM are proposed. They are (a) applying WIM to screen the overweight vehicles and utilizing AVI to transfer the information to weight station for further static weight checking, and (b) conducting the system on container trailers as experimental trial. |
