摘要: 为研究城市轨道交通分时定价的票价方案和公益性水平评价问题,本文从公益性角度出发,考虑票价和客流量的相互作用关系,以各时段的票价率为决策变量,基于交通方式影响因素和乘客出行选择行为,构建以系统乘客总出行时间最小为目标的双层规划模型;设计基于嵌套Method of Successive Averages的混合多种群遗传算法的求解方法;采用实际数据标定模型中关键参数,分析比较不同分时定价方案的票价率和公益性水平,提出基于公益性的分时定价方案。研究结果表明:在分时定价策略的效果中,能较明显地提升系统城市轨道交通公益性水平的方案为差别定价(高峰和非高峰票价下限和上限相同)和仅非高峰期降价策略,其中,前者的非高峰期和高峰期票价分别为0.1元·人-1·km-1和0.2元·人-1·km-1,相对于原票价方案使总广义费用和总出行时间分别降低12.75%和8.23%;较明显地降低公益性水平的方案为仅高峰期升价策略。

Abstract: This paper investigates the urban rail transit fare scheme and public welfare level of the time-sharing pricing strategy. Considering the interaction between urban rail transit fare and passenger flow, the study defines the fare rate of each time period as the decision variable and develops a two-level programming model with the goal of minimizing passengers total travel time of based on transportation mode and passenger travel choice behavior. A solution algorithm is designed based on a hybrid multi-population genetic algorithm with nested Method of Successive Averages. The field data was used to calibrate the key parameters in the model and analyze the fare rates and public welfare levels of different time-sharing pricing schemes. A time-sharing pricing scheme is then proposed based on public welfare. The results show that the schemes that can significantly improve the public welfare level of urban rail transit system include differential pricing (the lower and upper limits of peak and off-peak fares are the same) and price reduction strategy during the off-peak period. The off-peak and peak fares for the former are 0.1 and 0.2 yuan person-1⋅km-1, which reduces the total generalized cost and total travel time by 12.75% and 8.23% respectively compared with the traditional fare scheme. The scheme that significantly reduces the public welfare level is the strategy that increases price during peak hours.
