Abstract: We develop a GIS database to store urban traffic accident data in digital style, andanalyze these data in terms of their attribute and spatial characteristics to exploit the reasons of
accidents and rank urban area with dangerous degrees. We establish a road network in MapInfofor a sample city. Second we collect three years’ death traffic accidents data of the city and linkthese data with road network database with OLE connection between MapInfo and Visual Basic.We analyze reasons of traffic accidents to summarize major factors related to the accidents.Finally we create a hazard map to show the accident dangerous degree in the city.

Keywords: Traffic Accident, Hazard Map, MapInfo, Road Network and OLE

1. INTRODUCTION
As the soaring increment of car ownership in China’s cities and the poor traffic control system,road traffic accidents have been increasing rapidly and induced lots of economic lose. For
example, in year 2000 traffic accident per 10 thousand motor vehicles of Dalian city is 147.0,while 21.7% of them are death accidents. In order to handle traffic accidents, lots of informationhas been collected and large amount of documents are stored in police offices. However, worksof systematic analyses of the data are hardly done. Almost all studies on traffic accident in Chinaconcentrated on theoretical and conceptual analyses. For example, Mao (Mao et al, 2002) gavesome concept and structure to explain the causation of the accident, but no data or actual caseswere used in the analysis. Based on system theory Zheng (Zheng, 2002) used macro data,namely statistic traffic accident data on motorway, to analyze reasons of the accident in terms ofdriver, pedestrian, vehicle road condition and traffic management. Since actual urban traffic datahave not been analyzed based on city configuration, traffic and road condition and driver orpedestrian. Concrete reasons of the accident are not understood and effective counter-measurefor decreasing traffic accidents have not been found. One of the main reasons is that almost allconcerned documents are compiled and stored in analogue style. It is very difficult to search andProceedings of the Eastern Asia Society for Transportation Studies, Vol.4, October, 2003analyze accident information systematically. Some studies in Japan (SHIRAISHI et al, 2000,SUGIURA et al, 2000) took city as study area and use GIS to analyze the urban traffic accidentsand Danger Perception, while they just used GIS as a platform for storing data and somespatialcalculation.
Here we develops a GIS system to store urban traffic accident data in digital style, and analyzethese data in terms of their spatial and attribute characteristics to exploit the reasons of accidents(责任编辑:BUG)
