Title

(TECHNICAL- NOTE): IDENTIFYING RAIL ROAD LEVEL CROSSINGS WITH HIGH ACCIDENTS ON THE BASIS OF HAZARD INDEX

Pages

  223-231

Abstract

 Geometric conditions of road and railroad in their cross- points has fundamental role in increasing or reducing the number of accidents occurring between rolling stocks and road vehicles. In addition, traffic intensity, rail route system, type of crossing road vehicle, type of road super structure (asphalt, sandy and ground), crossing signaling system and sight distance (which is dependent to the crossing geometrical situation) are other parameters affecting the number and severity of the accidents. Considering the above mentioned points, the primary step to make the LEVEL CROSSINGs safety is prioritization and categorization of the crossings in higher, intermediate and low risky groups. In this paper, hazard index has been primarily defined considering the situation LEVEL CROSSINGs in Iran, by using experiences of some developed countries and then the existing LEVEL CROSSINGs in rail-road transportation network has been studied. In spite of increased number of rails as well as road vehicles, irregular development of the cities etc, it is predicted that up to the end of the Fourth Social, Economic and Cultural Development Plan of the Country, accident rate in level-crossings will be reduced to 20%, by fulfillment of the mentioned plan in Iran, and also it will be reduced from 44 average per year in the Third Plan to 30 accidents during the Fourth Plan.Statistical data analysis also showed some other results as follows:1- The LEVEL CROSSING accidents according to train - Km have had a descending trend,2- Specifying priorities of crossings according to the risk index has had more desirable and more realistic results3- The low cost safety measures have been considered in the short term plans and it is assumed that until the end of 2009, a 20% reduction will be witnessed in the crossings accidents compared to that of the Third National Development Plan.
