Analysis of road traffic accidents and ranking of sites severity: a case study of EL Minia / Beni-suef Eastern Desert and Agricultural Roads, Egypt

Abstract

Road traffic accident is a massive health hazard in Egypt and all over the world. Also, Road traffic injuries (RTIs) are a major cause of global mortality and morbidity. Available funds are insufficient to solve problems in all accident locations at the same time. Consequently, accident locations need to be ranked according to its severity for best allocation of available funds to repair the most severe locations. El Minia-Beni suif east and Agriculture roads are of the roads that have a highly repetition of accidents. This study compares between accident characteristics on both roads. In addition, areas of high accident occurrence are ranked according to its severity. Accident data on both roads is abstained from General Authority of Roads, Bridges and Land transport (GARBLT) for the period from 2010-2014. Analysis proved that Agriculture road has the major part of accidents, death and injuries. The maximum number of accidents on both roads occurs at kilometers between 20 and 30. The road section length of highly accident location on both roads is divided into subsections with length 2 km. These subsections are ranked according to its severity using the accident weight methodology. Accident weight is estimated using the economic cost of death, injury and property damage. Black spots are determined using Critical Crash Rate approach. Analysis proved that two locations on the study area can be considered as black spots. One on each road at the same km (24-26) is considered as a black spot. The present study recommends starting modifications with these two black spots sites then other locations according to its rank of severity. Also, the research recommends that the methodology introduced in should be used on all Egyptian roads. © 2016. Marsland Press, Zhengzhou University Language: en
