Application of Finite Queue Discrete Simulation with Controllable Delay Targets in Elevator Expansion Design

摘要:

上海闵浦三桥非机动车垂直交通系统为应对电动自行车电池安全隐患，管理方实施人车分乘模式测试，结果显示通行效率显著下降。为此，通过分析压力测试数据，建立了运送能力与可控延误时间的离散映射关系。并以20 min为延误目标进行微观仿真，结果表明：不同流量工况下的预估方法与微观仿真分析结果差异很小，能满足快速估算运输能力的需求；所提出的可控延误预测模型和有限队列离散仿真方法，为类似交通设施的资源配置提供了有效工具，同时指出了考虑客流时变性和经济性的未来优化方向。研究结果对跨江通道非机动车设施扩建规模具有重要指导意义。

Abstract:

In response to the safety hazards of electric bicycle batteries for the non-motorized vehicle vertical traffic system on Minpu Third Bridge in Shanghai, the managers have implemented a test on the passenger-vehicle separation mode. The results show a significant decrease in traffic efficiency. Therefore, by analyzing the pressure test data, a discrete mapping relationship between transport capacity and controllable delay time is established. And the microscopic simulation is conducted with a delay target of 20 min. The results indicate that the estimation methods under different flow conditions have little difference from the results of microscopic simulation analysis, which can meet the demand for rapid estimation of transportation capacity. The proposed controllable delay prediction model and finite-queue discrete simulation method provide an effective tool for resource allocation in similar transport infrastructures, and also the future optimization direction considering the passenger flow variability and economic efficiency is identified. The research results have significant guiding significance for the expansion scale of non-motorized vehicle facilities in cross-river passages.
