ABSTRACT
In recent years, along with the steady and rapid growth of China’s national economy and motor vehicles, modes of transportation have been developing hand in hand. The contradictions between the various elements of road traffic and the increasing traffic demand have become increasingly prominent. Because of the large speed discrete, the mixed traffic environment is becoming the concentrated area of traffic safety issues. The urban fringe, for example, has a complex traffic composition. Motor vehicles, non-motor vehicles and pedestrians are sharing the same road space, with large vans and small motor vehicles mixing together, which are typical features of mixed traffic. In addition, problems like dense township villages, heavy traffic, more entrances, inadequate transport facilities, the aggregation of markets, and illegal occupation of the lanes are more serious. These problems mainly increase the speed dispersion phenomenon in mixed traffic environment, which leads to increasing traffic conflict and brings about a major traffic safety problems. Thus, in connection with the reasons of traffic accidents in mixed traffic environments of urban fringe, it has become imperative to take appropriate measures to reduce casualties.
