Traffic collisions in space: four decades of advancement in applied GIS

Traffic collision analysis is essential for reducing traffic injuries. While most traditional approaches focus on the time dimension of traffic collisions, the recent past has witnessed a growing awareness of the spatial dimension in a geographical context. In this paper, 70 studies on the application of GIS to the spatial analysis of traffic collisions are reviewed. The purpose of the paper is to provide a systematic analysis of the major advancements in applied GIS for studying traffic collisions in space since the mid-1970s.
