In order to measure the traffic capacity of the expressway toll-gate comprehensively and reasonably, indicators are to be selected based on the combination of theoretical analysis and practice research, and then toll gate capacity measurement index system is built. The weight of the index is calculated by the hierarchical analysis method and the entropy weight method, and combination weight of each evaluation index is based on the linear combination of empowerment. The comprehensive fuzzy evaluation method is used to establish the capacity measurement evaluation model of the expressway toll station. Finally, the capacity calculation model is verified based on the example analysis, and suggestions for capacity improvement are put forward according to the result of sample toll station.展开更多

Highway emergency disposal dispatch problem is particularly important. This paper mainly studies the dispatching mode of the integrated collaborative dispatching system composed of road administration vehicles and unmanned aerial vehicles. Firstly, the influencing factors of the selection of integrated collaborative dispatching mode are analyzed. Then, according to the characteristics of ambiguity, uncertainty and imperfection in the evaluation data of non-metric indicators in the pattern selection process, the Evidence Inference Theory (ERA) is used to study the pattern selection. It further provides the basis for the formulation of expressway traffic management and emergency disposal dispatching strategies.展开更多
