“Developing a Breakeven Point Model Based on Enforce Rate for Installing Weigh in Motion System in Inter-City Transportation”, This paper was Published in the Journal of Intelligent Transportation and Urban Planning

Since freight transportation is growing up in developing countries, road pavement management is getting to be a serious concern for transport authorities. It is getting to be more important while a huge amount of investment budgets are required for construction and maintenance of roads and leads policy makers to tackle trucks’ overloading. One of the well-known methods to avoid pavement failure is to use Weigh In Motion system (WIM), which is an important component of Intelligent Transport Systems (ITS) and its usage is increasing to be applied for overloading enforcement. Installing weight in motion system is a constructive project with high investment in terms of special pavement, electronic devices, and data transferring devices and human, and it is necessary to develop a trade-off model between pavement cost repairing and installing weigh in motion system. Therefore, in this research work, a breakeven based model has been proposed to determine the minimum enforce rate according to the purchasing and installation, operating and maintenance costs. Repairing cost reduction on pavement is considered as income while the average overloaded axles under enforcement, performed by authorities to tackle overloading, is studied as a criterion and the proposed model determines the minimum average of overloaded axes in which installing WIM would be a profitable project. The proposed model has been developed in a parametric pattern, and an installed WIM system has also been selected as case study to determine the rate of required enforcement. Results revealed that the proposed model could help decision-makers to trade-off the cost of installation and reduction rate of pavement failure according to enforce rate applied by WIMs.
