Comparison of the cost of lost time due to the delay caused by the accident of transportation of dangerous substances in 2 routes with a common origin and destination (case study: Qazvin-Tehran routes)

In recent decades, the industrialization of the world has gained an increasing speed and has been accompanied by a greater amount of industrial production, and this has caused an increase in the transportation of goods and subsequently dangerous substances. Therefore, the purpose of this research was to compare the cost of lost time due to the delay caused by the accident of transportation of hazardous materials in 2 routes with a common origin and destination in the Qazvin-Tehran routes as a case stusy.

In the present research, the cost of delay caused by accidents and incidents of dangerous substances is calculated and compared to 2 different routes with the same origin and destination using a descriptive-analytical method. The case study in this research was 2 Qazvin-Tehran routes, which calculated the cost of delay caused by hazardous materials accidents at points with different AADT along the 2 study routes and compared with each other.

The findings of this research showed that the amount of wasted time on route 1 was 1441496 and on route 2 was 663268 person-hours, and the cost of delay in these two routes was calculated as 16.96 billion rials and 7.8 billion rials, respectively. By comparing the obtained calculations, the difference is more than 2 times the wasted time and its Rial cost is evident.

Therefore, the obtained criteria can be considered as one of the effective criteria in choosing the route in the transportation of dangerous materials and by making the necessary arrangements, a bed can be provided so that dangerous materials can be transported safely.
