轨道交通通道双向行人流分层规律

Lane Formation Rule of Bidirectional Pedestrians Flow in Rail Transit Corridor

为了探究轨道交通双向行人流的自组织规律及其管控策略,以行人实验为手段,通过对不同流量下的双向行人流的速度和转角参数特征分析,解析了双向行人流的微观行人特征,明确了双向行人流自组织分层现象形成阶段划分阈值及阶段特征,进而提出依据客流比增设护栏管控措施,并从效率和安全两方面进行优化措施的效果量化分析.结果表明:依据客流比增设护栏可有效缓解正向客流冲突.

To investigate self-organization rule and control measurements of bidirectional pedestrian flows,the microscopic pedestrian characteristics were analyzed under bidirectional flows based on two fundamental characteristics（ walking speed and turning angle） at different volumes,by using the method of pedestrian experiments. The lane formation phenomenon was quantitatively studied and three phases were identified. Then,the optimized measures were presented which a proposal of adding separating strap was raised based on flow ratio. The efficiency and safety of the countermeasures were demonstrated through a before-and-after comparison. Thus,the proposal of adding separating strap based on flow ratio can be effective in relieving conflicts.
