基于轨道区段锁闭时间的城轨列车运行图冲突检测研究

A Timetable Conflict Detection based on Blocking-time Theory for Urban Rail Transit Systems

为保证城市轨道交通系统的行车安全并提高其行车效率,在阐述城轨列车运行图编制模型及轨道区段锁闭时间相关理论的基础上,针对列车运行图编制过程中可能发生的列车运行冲突,即多列车同时请求使用同一资源,建立城市轨道交通线路和车站的微观模型和列车运行模型,提出基于锁闭时间理论的列车运行图冲突检测方法,并以北京地铁亦庄线为例,通过仿真分析正线冲突检测及折返段冲突检测,验证该冲突检测方法的可行性和有效性,对解决城市轨道列车运行图冲突自动检测具有重要意义。

To ensure the safety of urban rail transit system and improve its operation efficiency, based on the elaboration of the model of urban rail train diagram compilation and the related theory of track block time,this paper,aiming at detecting the possible conflicts arise when many trains request for one resource simultaneously,establishes a microscopic model and train operation model of urban rail transit lines and sta-tions,and it proposes a conflict detection method for train diagram based on blocking-time theory.Taking Beijing Metro Yizhuang Line as an example,the feasibility and validity of the conflict detection method are verified through the simulation analysis of the conflict detection of the main line and the return section.It is of great signifi-cance to solve the conflict automatic detection of urban rail train diagram.
