User Perception Of Transportation Service Level For Passengers Transportation Corridors

With the further improvement of integrated transportation system, the user demand of user gradually increased and diversified for passengers transportation corridors. Due to their own features, and the service level of transportation is different, the user can make a difference in perception, and compared with their travel demand to determine their own selection behavior. Different user perception will produce different choice behavior, so the analysis about perception process and perception calculating from the perspective of the user is the basic method of optimization of transportation choice, is also an effective way to realize the rational allocation of transportation corridor. Under the background of the coexistence development about multiple modes of transportation in comprehensive transportation corridor, this paper build the user perception model based on dynamic processes.First, this paper introduced the definition and characteristics of user perception, analyzed user perception mechanism. Then, according to user’s utility maximization theory, this paper determined the service level evaluation index and the related features for calculating user perception.Then, based on user perception and transportation service level interacting each other dynamically, this paper constructed index functions using share rate as the intermediary, created the user perception model under conditions of dynamic equilibrium.And in the aspects of sensitive coefficient, the subjective weighting method greatly influenced by the subjective will of the experts, can not fully reflect the development of the state of things.Objective method of determining the coefficient can not reflect the reality that user perception changed with the service level of transportation. This paper expressed sensitivity coefficient by the functional,set up the dynamic sensitivity coefficient expressions related to the user features.Finally,the model’s robustness and accuracy were verified via MATLAB programming using the Beijing—Xi’an Passenger Corridor as a study case. And according to the current existing research results, this paper constructed the static multi-factor model and dynamic generalized cost model to compared with the proposed model. The results show that: In Beijing Xi’an Passenger Corridor, high-speed rail and air services perceived levels more in line with user demand.The user perception calculated by the current existing research results had a certain gap with the reality. The user perception model constructed by the proposed method is more scientific and realistic.
