Study on Train Running Simulation of Railway Passenger Dedicated Line Based on Agent

不同制式的信号系统条件下的列车运行仿真问题是客运专线列车运行组织仿真中的核心问题之一。在分析列车运行与信号系统关系的基础上,提出应用Agent建立列车运行模型(TRAC)的思想,给出了TRAC的结构、形式化定义、内部决策机理,并重点研究了TRAC在不同环境下的自主性、反映性和适应性。在列车运行模型的基础上,编程实现了系统原型。仿真结果表明,基于Agent技术设计和开发的系统能够很好地满足客运专线列车运行组织仿真的需求,具有良好的通用性、可重用性和可扩展性,对客运专线运输组织理论与方法的研究提供了一个研究平台。

Train running simulation under different pattern signaling systems is one of the key issues of passenger dedicated line（PDL） rail traffic organization simulation.On the basis of analyzing the relationship between train running and signaling system,a train running model based on agent technology（TRAC） was applied to solve train running problem under different pattern signaling system.The structure model,formalized definition,decision-making mechanism of TRAC were studied.At last,a simulation system was designed and developed based on TRAC.Now the system runs well with high generality,reusability and expansibility and it provides a platform for PDL rail traffic organization theory and method study.
