城市轨道交通大小交路结合快慢车开行方案优化

城市轨道交通线路可以实行大小交路的开行模式,以克服断面客流不均衡导致的能力浪费,而这种模式使长距离乘客的出行时间增加,可以在列车开行大小交路的基础上考虑开行快慢车。以乘客出行成本与企业运营成本最小为目标,考虑列车停站时间与客流需求的关系,将停站时间纳入乘客出行成本,建立双目标非线性整数优化模型,求解乘客与运营企业的成本博弈均衡点。通过算例验证模型的有效性,结果表明,相对于大小交路嵌套的运营模式,实行"大小交路+快慢车"的运营模式可以有效降低乘客出行成本与企业运营成本。

Optimization of Operation Scheme for Urban Rail Transit Combining Full-length and Short-turn Routing with Express and Slow Train

To overcome the waste of transport capacity caused by the uneven passenger flow,urban rail transit lines can carry out the operation mode of full-length and short-turn routing,however,this operation mode will increase the travel time of long-distance passengers,so that it can be solved by express&slow trains based on full-length and short-turn routing.Taking the minimum of passenger travel cost and enterprise operation cost as the objective,considering the relationship between train stop time and passenger flow demand,this paper analyzes the stop time in passenger travel cost,and a double objective nonlinear integer optimization model is established to solve the cost game equilibrium point between passengers and operation enterprises.The validity of the model is verified by a case,and the results show that the implementation of“full-length and short-turn routing+express&slow trains”operation mode can effectively reduce the travel cost of passengers and enterprise operation cost.
