road traffic accidents and the effects they subsequently incur are increasing dramatically, and estimating the cost of road traffic crashes could be a vital step in improving the recognition of this widespread problem. the main objective of this paper is to estimate the cost of road traffic crashes in iran using the human capital (hc) method. results of this study indicate that the cost of road...

This paper provides an international overview of the most recent estimates of the social costs of road crashes: total costs, value per casualty and breakdown in cost components. The analysis is based on publications about the national costs of road crashes of 17 countries, of which ten high income countries (HICs) and seven low and middle income countries (LMICs). Costs are expressed as a propo...

Determining the efficient density for forest roads is essential to decrease the costs of skidding and road constructing in forestry plans. In order to estimate the optimal density for road network in Dalak kheyl forest district (Mazandaran Wood and Paper Industries), we calculated the roading costs and hourly costs of Timber jack 450C and HSM 904 skidders. The length of skid trails was measured...

Although autonomous vehicle (AV) technology is expected to bring dramatic societal, environmental, and economic benefits, the high cost might slow adoption of AVs. This paper explores an infrastructure-enabled driving system, which a promising remedy Specifically, system combines vehicles infrastructure in realization driving. Equipped with roadside sensing, computing, communicating devices, or...

BACKGROUND Road traffic deaths are a major global health and development problem. An understanding of the existing burden of road traffic deaths in the population is necessary for developing effective interventions. OBJECTIVE To outline systematically the global distribution of road traffic deaths by road user groups (pedestrians, bicyclists, motorcyclists, motorised four-wheeler occupants). ...

In urban networks, traffic signals are used to control vehicle movements so as to reduce congestion, improve safety, and enable specific strategies such as minimizing delays, improving environmental pollution, etc (Teklu et al., 2007). Due to the increasing in the number of cars and developing industry, finding optimal traffic signal parameters has been an important task in order to use the net...
