Abstract

While passenger and freight transportation are growing up in developing countries, traffic congestion, accidents and environmental pollution are getting to be a serious concern for policy makers. Using Intelligent Transportation Systems (ITS) has been recently introduced as a main solution to overwhelm the above problems. Since, Weigh In Motion system (WIM) is known as a very important component of ITS, its usage is increasingly to be applied for overloading enforcement. Huge investment in construction and maintenance of pavement lead policy makers to tackle overloading using weigh in motion systems.

Installing weight in motion system is a constructive project with high investment in terms of special pavement, electronic devices, data transferring devices and human resource to overloading reduction and save pavement condition in the proper situation. Following the above mentioned, it is necessary to develop a trade-off model between pavement cost repairing and installing weigh in motion system. So, in this research will be presented on the basis of break-even at the cost of purchase, installation, operating and maintenance costs of the system and saves the cost to repair the pavement as the top model in terms of the income. The average overloaded axles under enforcement performed by authorities to tackle overloading is studied a criterion and the proposed model determines the minimum average overloaded axes in which installing WIM would be a profitable project.

The proposed model is as a parametric pattern and an installed WIM system has also been selected as case study and the number of required enforcement. Results will help decision-makers in the field of transport, as in the operation of WIM to achieve a balance between costs and revenues from it the right decision to take.
