基于元胞自动机的落客平台仿真研究

A Study on Simulation of Drop-off Region based on Cellular Automata

铁路枢纽落客平台是铁路旅客集散的重要场所之一,其通行能力影响旅客的出行体验及进出站效率。为了提升落客平台运行效率,缓解落客区拥堵,以元胞自动机为理论基础,以落客平台运行特征为现实依据,基于C#语言开发落客平台仿真系统,以南京南站北落客平台为例进行仿真模拟。仿真结果表明,该仿真系统能够较为准确地模拟落客平台的交通流运行特征,通过调整车辆优先落客位置,发现将优先落客位置调整至中游和下游区域可将通行能力分别提高约6.7%和12.5%,为新枢纽落客平台的设计建设及已建成枢纽落客平台的运输组织优化提供理论依据。

The drop-off region is the essential links for railway passenger distribution,affecting the passengers’travel experience and the efficiency of entering and leaving the station.To improve the operation efficiency of the drop-off region and relieve congestion,based on the theory of cellular automata,according to the operation characteristics of the drop-off region and drop-off region simulation system developed by C#language.The results show that the simulation system can accurately simulate the traffic flow characteristics of the drop-off region.By optimizing the alighting position,it is found that adjusting the alighting position midstream and downstream can increase the traffic capacity by 6.7%and 12.5%,which provides a theoretical basis for transportation organization optimization of the new hub’s design and construction and the completed drop-off region.
