The goal of this research is to identify and analyze the accident hotspots on a road network. To develop a model to optimize the individual risk on a road network and to suggest necessary improvements and safety measures to reduce the road accidents. This research work was carried out in four steps. The first part of the research was to identify the methods and models for identification of Individual Risk on the regional road network and to study GIS application for Identification of Individual Risk on the regional road network. The second part of the research deals with the case study and a research methodology has been proposed. An Interactive Model for Identification of Individual Risk on the Regional Road Network Using Arc GIS software is developed. In the third part of the research the accident data was analyzed by using Crash Severity Method. In the last part of the research the results obtained
was discussed. By analyzing the accident data the various causes of accidents was identified. Finally the research is concluded by suggesting remedial measures and provisions for traffic safety are suggested
