In order to represent the fuzzy attribute of traffic state, this paper first analyzed the characteristics and spread mechanism of traffic congestion on urban road network. Then a traffic state coefficient was introduced to measure the congestion level on road sections. On the basis of cloud theory, a fuzzy method of traffic state identification was proposed. By constructing judgment matrix, an analytic...
To deal with the problem of emitter platform identification caused by the feature measurement uncertainty of the platform from multi sensors, this paper proposes a new identification algorithm based on interval Dempster-Shafer theory (EDST), which models the identification output of each sensor as interval values and combines the interval outputs through interval evidence combination rules. A number...
In solving the decision-making problems of complex multi-index evaluating scheme, the traditional way is to adopt fuzzy unified evaluating method. But the traditional fuzzy evaluating method has a lot of shortcomings, e.g. being unable to fully reflect the intended purpose of fuzzy evaluation, because it is difficult for experts to score an evaluating index definitely; sometimes hardly providing a...
