TRAFFIC ACCIDENT ANALYSIS WITH GIS AND STATISTICAL PACKAGE

This paper tries to propose a Geographic Information System (GIS)-integrated accident management framework - how traffic accident and safety management can be implemented in a GIS based information system supported by a statistical analysis system. The basic motivation for this research stems from the fact that traffic accidents for various geographic coverages are highly related to natural and artificial elements of road conditions such as slope, curvature and transportation facilities. Therefore, storing accident data in a GIS database is not only efficient in managing information, but effective in making decisions about traffic accident reduction. In order to demonstrate this hypothesis, the authors built a database of natural conditions (roadway condition such as slope and elevation), socioeconomic status (income, etc.) and past traffic accident data for the city of Suwon, using MapInfo and ARC/INFO. Then, statistical analyses for the accident prone geographic areas were conducted by links and intersections. In addition, spatial distribution patterns of accidents, along with their implications, were identified based on two coefficients.
