摘要
以行人路径的完整过程为研究基础,分析组成路径的不同设施对行人路径选择以及路径效用的影响,同时对同种类型设施在不同路径中的效用值做了深入的调查分析,并根据效用最大化理论,建立了改进的Multinomial Nested Logit(MNL)模型和路径效用函数。通过对轨道换乘车站行人路径选择的跟随问询调查,研究影响行人在轨道车站换乘区域内路径选择的因素。根据效用最大化理论,建立了改进的Multinomial Nested Logit(MNL)模型和路径效用函数。以北京市地铁国贸站换乘调查数据为基础,标定了模型参数。模型分析表明:行人在轨道车站换乘区域的路径选择与出行目的及各交通换乘设施的走行时间有关;同时,路径重复系数对路径效用的影响较大,进而影响路径选择行为,佐证了行人对拥挤路径的规避行为;得到的模型具有很高的精度,为评价和提高轨道换乘车站设施服务效率提供理论依据。
Based on pedestrian path tracing, this paper analyzed the influence of different facilities on pedestrian route choice path selection and route utility in the Transfer area of subway station, and the utility value of the same type facility in different routes. Through the investigation of pe- destrian route choice, it studied the factors of pedestrian route choice in the Transfer area of sub- way station. According to maximum utility theory, the improved multinomial nested logit （MNL） model and route utility function were established, and the parameters of this model were determined. The model analysis shows that pedestrian route the choice is related to trip purposes and travel time on the facilities, and path overlap factor has big effect on route utility. The con- clusion provides proofs with the circumvention of the crowded path. The model established has high accuracy, and could provide theoretical basis with the evaluation of subway station service in the Transfer area of subway station. 4 tabs, 20 refs.
