| Summary: | Road accident rate in Malaysia keep increasing over the year. Since then a lot of precaution step, research, life and cost taking apart. However, most of road accident cases are from the group of motorcyclists. To overcome and controlled this trend, the Malaysia society should be aware as a group, because this problem cannot be solved in a single entity. In the identification of the cause of road accidents, decision-makers often need as much information as possible before attempting to make decisions about appropriate measures. Accurate statistical prediction and visualization of information graphically are important for the study of road accidents. Geographic Information System (GIS) technologies, has been applied in this study for analysing the distribution of road accidents and their factor. The main issue that has been focus for this study is the impact of road defect for the motorcycle accident cases in the study area. By using GIS technologies, this is the best medium to determine the relationship of road defect impact in road accidents and for the road safety especially for the group of motorcyclists as well as for effective supervision. GIS tools have become one of the most commonly used programs for the various fields of study and project. It has been widely used in a variety of applications for planning, presenting and analysing the data and result. © Published under licence by IOP Publishing Ltd.
