The paper proposes an evaluating method of traffic conflict based on grey cluster theory by means of regarding TC/MPCU as index, which provides a new evaluation method for safety of freeway weaving section.
In the simulation test, we found the length of extra lane and divide line, the rate of bus and bicycle driving behavior on supplement road, the length of waving area have different affect on diamond interchange exits of Urban Expressway.
The factors that influence the traffic characteristics of wave area mainly are the waving length,waving style,waving traffic flows and the design speeds in waving area. With the micro simulation tool VISSIM,these factors are studied.
Based on the theory analysis of summarizing the research document of interweaving area. From the vehicle operation courses, the relation between traffic conflict technology and its influence factor is investigated and a predictive model based on artificial neural network (ANN)is presented.
Based on above model,safety appraisal and ameliorative flows are presented aim at weaving area of the superhighway and built projects so as to systematically improve safety condition at Interweaving area of the high-type highway.
