改进Ramsey模型的城市公共交通分时段定价方法研究

Research on the Time-based Pricing of Urban Public Transport Based on Improved Ramsey Model

考虑城市公交服务均等化、乘客接受程度、地方财政补贴能力等因素,合理确定城市公共交通票价是急需解决的新课题。以改进拉姆齐模型为理论依据,根据客运量的不同,构建分时段的城市公共交通定价模型。利用我国某一地区城市公交的运营数据对所建立的模型进行标定和求解,验证了模型的科学性和有效性,为决策者制定多样化的公交票价结构提供理论依据。

Taking into account the equalization of urban public transport service,passenger acceptance and the ability of the local financial subsidies,a reasonable determination of urban public transport fare is a new topic which needs to be resolved urgently.According to the different passenger volume,time-based pricing model is established on the basis of improved Ramsey model.The survey data of urban public transport in an area is used to calibrate and solve the model.The result verifies the scientific and effectiveness of the model.The theoretical basis is provided for making diversified fare structure.
