【Abstract】 GIS-based road traffic safety management and assessment system is a visualized and convenient tool that provides decision-making support for road traffic saf ety management including black spots analysis, traffic safety assessment and pre vention of traffic accident. This paper defines the system objective and gives t he functional partition based on the current demand of the road traffic manageme nt, and then puts forward the system design and implementation methods. The system i s developed by integrated mapping, which uses programming tool Visual C++ and in tegrates MapInfo by OLE Automation. A road traffic safety management and assessm ent system is set up for traffic safety analysis of a certain city, which realiz es functions such as display of traffic accidents spatial distribution, factor a nalysis of traffic accidents, traffic safety assessment, etc.更多还原
