摘要

Geographical information system (GIS) has been used more and more widely. Nowadays, the technology of GIS can play a vital role in the management system with its strong capability of processing spatial data information. Considering the actual needs of traffic and transportation at present, it has important practical significance than promoting safety management and intelligence of urban traffic by means of establishing geographical information system for transportation (GIS-T) which refers to application of GIS and modern computer technology. Especially under the abnormal conditions, such as urban road traffic accident, construction site, weather conditions or rush hours, that makes urban traffic safety management more difficult. In this case, it is of great significance that analyzing existing problems in urban traffic which badly needs to be resolved and discussing safety management of urban traffic and its affected factors, afterwards some measures are also proposed. Finally, it describes the design principle and frame of a monitoring and forewarning system of urban traffic safety based on GIS.
