Abstract

Injuries caused by accidents have various economic, social, cultural, environmental, health and human dimensions, and in order to understand the extensive range of these losses and allocate sufficient resources to control it, the amount and quantity of losses must be properly specified. One of the subjects related to accidents is the costs that it imposes on the government and society, and in order to reduce these costs, it is essential to take serious measures. Given the fact that various aspects of the cost of accidents have been discussed in other studies, while the friction cost has not been adequately addressed, the present research attempted to estimate the friction cost of urban accidents. In this approach, the types of urban road accidents are separated in terms of severity, and a calculation method is provided to calculate the friction cost, which includes the cost of replacement, new employment, and training caused by accidents. Finally, due to the importance of Tehran and the high number of accidents in this city, the friction cost was estimated for this city. The friction costs imposed on the economic system as a result of the accidents occurred in Tehran in 2020 are equal to 730, 911, 800, 000 Rials. The results of these studies can be utilized for a more accurate estimation of the cost of accidents and the allocation of safety budgets to urban roads and urban areas.
