基于旅客出行方式选择的高速铁路客运分时定价方案研究

高速铁路(简称:高铁)客流一天之中具有较大的波动性,呈现出高峰、平峰、低谷的特点。文章利用“削峰填谷”思想,基于分时定价理论和Logit效用函数,考虑旅客选择出行方式的行为因素,以及线路通过能力、客车容量等约束,建立以高铁企业收入最大化为目标的分时定价模型,并利用遗传算法进行求解。通过某铁路线实际算例,验证上述模型和算法的可行性。验证结果表明,高铁分时定价策略有助于提升高铁市场占有率及运营企业客运收益。

铁路提速对民航客运影响的实证分析

利用铁路系统 5次提速前后国内各民航机场旅客运输量的综列数据,通过对处理综列数据方法的经济计量学模型的估计和实证分析,得出如下结论:尽管我国民航旅客运输量在近几年不断攀升,但这是由于国内生产总值高速增长即经济快速发展的结果,若排除国内生产总值快速增长的影响因素进行分析,铁路提速对民航客运量的影响实际上是下降了。

Research on Behavior on Travel Mode, Going to Metro Station at Ho Chi Minh City

This research presents an analysis of travel mode choice for trips to Ho Chi Minh City metro station. Research methods were inherited through a formula to calculate passenger traffic forecasts to predict passengers, going to the station. Based on the collected data of interviews, traffic surveys, and ＂Irwin ＆ Von Cube＂ function, forecast the proportion of travel mode, and use to go to the station and leaving from the station. The results of study are used for the purpose of calculating the size of the metro station parking lots and parking layout plan.
