摘要:
传统运营组织模式下，城市轨道交通长大线路运能不能满足高峰时段超高峰客流需求，需要通过优化运营组织方案提升长大线路运能。分析了上海轨道交通长大线路客流特征，以及传统运营组织模式下长大线路运能供给与客流需求之间的主要矛盾；介绍了以客流为核心的长大线路运能精准匹配策略；以上海某轨道交通线路为例，分析了突破折返能力制约的极限运能运营组织方案。研究结果表明：传统运营组织模式下，高峰时段断面运能受线路折返能力制约，采用存车线插车方式增加运能，也只能做到少量非连续增能；长大线路的高峰时段高断面客流区间相对固定、超高峰持续时间较短，可通过停车场ATC(列车自动控制)改造、优选插车地点、缩短行车间隔、不对称运行交路、远端停车场收车等综合策略，形成以单向运营为特征的运营方式，突破线路折返能力制约，实现高峰时段局部区段、连续超高密度的行车组织方案，进而实现线路运能精准匹配高峰期超高峰客流需求。
Abstracts:
Under conventional operation organization mode, the transportation capacity of urban rail transit long large lines can't meet the passenger flow demand during peak and super peak hours. It is necessary to improve long large line transportation capacity by optimizing operation organization scheme. The passenger flow characteristics of Shanghai rail transit long large lines are analyzed, as well as the main contradiction between the supply of long large line transportation capacity and the demand of passenger flow under conventional operation organization mode. A precise matching strategy for the long large line transportation capacity centered on passenger flow is introduced. Taking a certain line of Shanghai rail transit as example, the operation organization scheme of extreme transportation capacity that breaks through turn back capacity constraints is analyzed. Research results show that under conventional operation organization mode, the sectional transportation capacity during peak hours is limited by turn back capacity while adopting storage track insertion method can only increase little capacity discontinuously. The long large line interval of high sectional passenger flow during peak hours is relatively fixed, and the duration of super peak hours is short. Comprehensive strategies can be adopted, such as depot ATC (automatic train control) transformation, train insertion location optimization, train headway reduction, asymmetric routing operation, and train collection at remote depots, to form a one way operation mode and break through the line turn back capacity constraints, constituting an operation organization scheme for peak hour segments and continuous super high density. This enables precise matching of line transportation capacity with passenger flow demands during peak and super peak hours.
