摘要
随着客流的不断增长,既有大连快轨3号线已不能满足运营的要求,需对信号系统进行扩能改造。经分析,通过减少现有所有的锁闭区段数量,允许司机在预告减速的信息码区段上追踪运行,对现有闭塞分区进行必要的调整等改造措施可使既有快轨3号线的追踪间隔由4 min减少到3 min。
With the increase of the passenger flow, the existing Dalian light rail transit line 3 cannot meet the requirements of traffic capacity, in view of the situation, it is necessary to reconstruct the signal system of the line. Through the analysis, the paper puts forward the methods of reducing existing locking sections, allowing the train following in the section with a warning deceleration code, making necessary adjustment to existing blocking section etc., in order to reduce the time interval of the line from 4min to 3min.
