In-depth statistical analysis of accident databases. Part 2: A case study

The main aim of this research is to develop a generic approach for the utilization of statistical methods to conduct basic as well as in-depth investigation of accident databases. This is meant to obtain accident characteristics as well as to isolate accident causes and hence assist in the selection of specific appropriate traffic safety countermeasures. The paper presents a full description of the developed approach. The applicability of the approach is demonstrated by analyzing 1998 accident database for the main rural roads in Egypt. In this context, the paper presents and discusses the results and conclusions of the indepth statistical analysis of accidents occurring on the Egyptian rural road network and establishes, in statistical terms, the specific characteristics and causes for such accidents. Such focused conclusions are used to suggest some specific safety countermeasures.
