基于客流与行车协同的城市轨道交通线网调度指挥系统研究

Research on Dispatching Command System for Urban Rail Transit Network Based on Passenger Flow and Train Operation Coordination

通过对城市轨道交通线网调度指挥现状剖析,发现存在运输能力和运输需求匹配分析不足的问题,客流引导和行车调整很难做到协同处理。针对该问题,在线网调度指挥系统中提出客流与行车协同分析的思路和方法,构建协同分析的数据处理流程,提出协同问题解决方案及线网客流与行车综合推演、线网客流与行车预测、拓扑路径建模与寻优等关键算法模型,并阐述了客流与行车协同的优点。将客流数据和行车数据深度结合,对线网调度指挥系统三层技术架构及客流与行车协同分析的调度辅助决策、客流和行车协同分析的应急行车协调指挥等2个核心功能进行设计。经试点应用,该方案既能高效疏导客流,又兼具节能效果,提高了应急处置效率,降低了应急情况下对乘客的影响。

After dissecting the current dispatching command system for urban rail transit networks, this paper found that the matching between transportation capacity and transportation demand was analyzed insufficiently, and it was difficult to coordinate passenger flow guidance and train operation adjustment. To solve these problems, this paper introduced passenger flow and train operation coordination into the dispatching command system and constructed the data processing flow for collaborative analysis. In addition, the paper proposed solutions to collaborative problems and key algorithm models such as comprehensive deduction and prediction of passenger flow and train operation in the network, as well as topological path modeling and optimization, and it expounded on the advantages of passenger flow and train operation coordination. By combining passenger flow data and train operation data, the paper designed a three-layer technical architecture of the dispatching command system and two core functions including dispatching auxiliary decision making and emergency train operation coordination and command for collaborative analysis of passenger flow and operation. After the pilot application, it was found that the scheme can divert the passenger flow efficiently, save energy, improve the efficiency of emergency response, and reduce the impact on passengers in emergencies.
