Identification And Analysis Of Black Spot On The Road In Urumqi And Research On The Traffic Accident Information System Based On GIS

Based on the project "Traffic Safety and Road Accident Analysis in Urumqi (The World Bank financed project)", this paper put forward some idetification methods of accidents black spot from point of network level system and project level system aimed at road safety conditions at present in Urumqi, then on the basis of analysis of cause and characteristic at black spot of target district , the influences of road and environment on traffic accident are emphasized. Furthermore, some correlative concrete countermeasures are provided to reduce traffic accident rate in Urumqi. As a advanced supplemental means, the technology of Geographic Information Systems(GIS) can play a vital role in city traffic safety system with its strong capability of processing spatial data information. In the chapter 4, for the aim to realize the ideas mentioned above by means of GIS,this paper has made a study on some key technology in depth, meanwhile,the detailed analysis is made on the function and composition of GIS-Based Urumqi Traffic Accident Information System.
