基于客流导向的长大市域轨道交通组织优化方法研究

Optimization method of urban rail transit traffi c organization based on passenger fl ow guidance

以北京市轨道交通平谷线为依托,基于线路功能定位和客流需求,对车辆选型、运营交路方案进行探索性创新研究。提出一种行车组织优化模型及求解算法,并以运力运量、工程投资、客流-车流匹配率等关键性指标为比选目标,确定该市域快线的最佳行车组织方案,以期为类似市域快线行车组织方案的合理选择提供理论支撑。

Based on Pinggu line of Beijing rail transit practice,and based on line function orientation and passenger fl ow demand,this paper makes exploratory and innovative research on vehicle selection and operational train connection scheme.It puts forward a traffi c organization optimization model and solution algorithm,and takes the key performance data such as traffi c capacity and volume,construction investment,passenger flow vehicle flow matching rate as the comparison benchmarks to determine the best traffic organization scheme of the urban express line,so as to provide theoretical support for the optimal selection of traffi c organization scheme of future urban express lines.
