Abstract

The great potential accidents’ risk involved on and in the vicinities of BRIDGEs, has been gradually more evident by vehicles’ technology progress and the increase in their obtainable speed and acceleration. This risk is related to the high number of accidents and casualties, which are caused by hitting roadside obstacles and/or prolabsus to the nearside valleies, rivers, lakes, etc. In this research-work the physical and traffic characteristics related to nineteen BRIDGEs, which are selected from initially twenty five nominated BRIDGEs in rural roads in the province of khorasan; were collected. Then a set of mathematical operations including development and expansion of statistics REGRESSION models, which possess the capabilities of predicting ACCIDENT FREQUENCIES in accordance with effective independent variables; were carried out. The results show that among physical and mathematical BRIDGEs’ characteristics, the reduction of shoulder width has the highest impact on the BRIDGE traffic safety. The traffic mixed interaction and intervention and also the BRIDGE width, are almost equally the next most effective factors.In the process of this research-work for the first time, a “BRIDGE SAFETY INDEX” model, which is specifically generated, for IRAN rural roads; is developed. This model can be economically beneficial and generate important decision-making results, including prediction of BRIDGEs’ traffic safety, optimization of BRIDGEs’ rehabilitation and maintenance expenditures, and defending related financial resources.
