ABSTRACT In this paper, effort has been made to map out road accident prone areas in Jalingo metropolis using Geographic Information System (GIS) and Global Positioning System (GPS). Street guide map of Jalingo metropolis and road accident data for the year 2009, 2010 and 2011 were used in identifying and mapping of the accident prone areas. GPS coordinates were taken and used for geo-referencing and digitization using AutoCAD Land Development and Arc GIS 9.2 which give the digital map of accident prone areas. In addition, accident particulars for the year 2009, 2010 and 2011 such as, location, type of vehicle involved, and number of persons injured or dead were also collect and included in a GIS database. It was revealed that year 2011 had the highest number of accidents due to the growing population and increase in number of vehicles. The result revealed that the distribution of accident varies depending on the types of road surface at the time of accident, the type and number of vehicles involved in the collision. It is recommended that Police, Road Safety, VIO official and other transport workers will find this study useful in identifying remedial measures for the improvement of safety.
