Study Of Analysis And Evaluation For Expressway Capacity And Service Quality

This paper studies the problem of traffic capability and service quality evaluation in expressway. On the basis of the analysis on the traffic capacity and service level of expressway basic road, this paper studies systematically the basic theory of traffic capacity in expressway charging system. According to the traffic behavior of vehicles in charging station, this paper establishes a traffic model conforming to the actual situation, carries on deep analysis on arrived distribution model of vehicles and service time distribution model, and gives the calculation formula of traffic capacity and targets reflecting service level of expressway charging station. The model, synthesized several factors of traffic characteristic, traffic behavior, the charge station scale and service characteristic etc., tallies with the actual traffic circulation, may provides the standard for the design and valuation of expressway charging station. Through the analysis on concept, connotation and characteristic, this paper brought forward the objective function of expressway service quality.On the basis of analysis on function, characteristic and traffic characteristic of expressway, this paper carries out thoroughly analysis on the influence factors of expressway service quality with the system theory method, and proposes the composes system of influence factors in expressway service quality. On the basis of qualitative analysis of influencing factor system, according to the content, purpose and characteristic of expressway service quality, this paper choice the major effect factors and builds the appraisal index system of expressway service quality. Using the AHP method, this paper establishes level-structure analysis model, and determines the weight of various targets by theoretical analysis and experts consultation. And through analyzes and refers to the research results and present profession standard in domestic and foreign, this paper proposes the evaluation criteria suggestion value of expressway service quality; carries on the study on the attribute value calculation and zero dimension of index, applies the principle and method of fuzzy mathematics overall evaluation, puts forward the multi-level fuzzy synthesis appraisal model of expressway service quality according to the realization degree of service quality target(rank division).According to the current situation of expressway service quality in China, combining the exist operation of Xilin expressway, this paper establishes the model to the partial syntheses appraisal index, produces the computational method, carries on the synthesis appraisal and analysis, and proposes the main problems that the expressway service quality facing. Based on the appraisal result and influencing factors, this paper puts forward the strategy and suggestion to improve the express highway service quality.
