- Abstract:
- The previous method in safety evaluation of urban traffic just proced part of the uncertain information,while the SPA (Set Pair Analysis) theory was able to process and describe all the fuzzification and indeterminacy caused by uncertain factors uniformly.This paper adopted SPA to evaluate the safety of urban traffic.Taking urban traffic system as the object,the evaluation was conducted in the following two aspects.Firstly,it was to build the SPA model of index weight and to analyze the weight of influential factors;Secondly,it was to group the actual targeted value and the standard targeted value into two sets,which were consequently formed as one set pair.Due to the different evaluation criteria,there might be several set pairs.By calculating the connection degrees of those set pairs,the grade with the highest connection degree would be chosen as the final evaluation result.The feasibility and actual value of this method were verified by instance analysis.
