无越行线市域快线的快慢车组织探讨——以深圳14号线为例

Discussion on the Organization of Fast-slow Modes on the Urban Rail Rapid Transit Without Overtaking Lines––Taking Shenzhen Line 14 as an Example

针对连接城市中心区和郊区的城市轨道交通线路运行时间长、发车频率低等问题,从行车组织灵活性方面,研究市域线组织快慢车模式的可行性和有效性。分析城市轨道交通市域线快慢车运营组织的特征,总结国内外典型线路的先进经验,以深圳地铁14号线为例,提出考虑乘客等待时间和列车发车间隔均衡性的优化方案,从时间角度探讨无越行线市域快线的大站快车组织方案的效果,为14号线列车运行图的优化调整提供参考。

In view of the problems of long running time and low departure frequency of urban rail transit lines connecting urban central areas and suburbs,the paper studies the feasibility and effectiveness of the fast-slow mode organized by the regional rail from the perspective of traffic organization flexibility.This paper analyzes the characteristics of the fast-slow train operation organization of the regional rail,and summarizes the advanced experience of typical lines at home and abroad.Taking Shenzhen Metro Line 14 as an example,this paper puts forward an optimization scheme considering the balance of passenger waiting time and train departure interval.From the perspective of time,the effect of the express train organization scheme of the urban rail rapid transit without overtaking line is discussed,which provides a reference for the optimization and adjustment of train diagram of Line 14.
