The present research differs. It focuses on developing a GIS based road crash analysis and referencing system. The main objectives of the current research are (1) to diagnose the current available accident data management system in GARBLT, (2) To utilize GIS to develop a framework and detailed plan to upgrade the current accident data collection, analysis, reference and management system. This research presents the overall system framework. It also, shows the system capabilities and the benefits associated with its implementation. The developed system can handle different types of crash analysis, e.g. spot, cluster, corridor, sub area, and area wide type of analysis. It can produce different report configurations such as tables and graphs. Also, it can store scanned reports, photos, and Video logs. The developed system utilizes the use of currently available GIS based road network. Keywords Road accident , Road safety , GIS ,
