摘要: 跨线运行是区域轨道交通网络化运营的重要方向。本文面向市域铁路多运营主体共线运行场景,对比分线编制与一体编制两种模式,以本线净效益最大化为目标,在通过能力和车底资源等现实约束下构建本线与跨线列车开行方案协同优化模型,统筹多方收益归属与跨线运营方经济可行性,并以超额出行时间度量乘客出行时间损失;模型在列车候选集上联合决策开行频次、编组与客流分配,经精确线性化转化为混合整数线性规划,由Gurobi求得最优解。以上海市域铁路机场联络线跨线运营为例,结果表明:跨线运行较无跨线方案提高本线运营收益,缩短乘客出行时间,净效益指标可有效兼顾收益与服务;一体编制本线净效益较分线编制高15.2%,其增量主要来源于运营收益提升,分线编制的增量主要来自超额出行时间改善对应的时间价值。超额出行时间仅占总出行时间约12.4%,却是开行方案可改善的主要部分,以其为指标比总出行时间更能识别跨线运行带来的服务差异。灵敏度分析表明,跨线列车频次上限与共线收益要求较低时,分线编制可在维持本线方案不变的前提下提高净效益;两者较高时宜采用一体编制。所建模型与对比框架可为本线运营方评估跨线运营方案和选择编制模式提供量化依据。

Abstract: Through-running services are a key path toward regional rail integration, but shared-corridor operations with multiple operators require coordination of service quality, capacity, and revenue attribution. This paper compares separate and integrated planning for suburban railways and develops a collaborative optimization model that maximizes host-line net benefit under capacity, rolling-stock, and economic-viability constraints. The model uses excess travel time (ETT) to measure passenger time loss, jointly optimizes train frequency, composition, and passenger assignment, and is reformulated as a mixed-integer linear program solved by Gurobi. In a Shanghai Airport Link case study, through-running increases host-line operating revenue and reduces passenger travel time relative to no through-running. Integrated planning achieves a host-line net benefit 15.2% higher than that under separate planning, mainly through higher operating revenue, whereas separate planning gains mainly from reduced ETT. Since ETT accounts for only about 12.4% of total travel time but represents the main component that can actually be improved, it identifies service improvements and planning-mode differences more sensitively than total travel time. The sensitivity analysis shows that separate planning is beneficial when the through-running frequency limit and co-line revenue requirement are low, while integrated planning should be adopted when both are high. The framework supports quantitative evaluation of through-running operations and planning-mode selection.
