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, data transferring devices, and human resources, making a trade-off model necessary.
Therefore, in this research work, a breakeven based model has been proposed to determine the minimum enforce rate according to purchasing, installation, operating, and maintenance costs. Repairing cost reduction on pavement is considered as income. Results revealed that the proposed model could help decision-makers trade off installation costs against pavement failure reduction rates based on enforcement levels.
