摘要:
合理地评估城市轨道交通车站内客流拥堵风险，对车站运营安全管理具有重要意义。基于现有的服务水平等级标准，结合密度分布、速度分布和客流流线提出拥挤区域的判别方法，引入指定密度、持续时间等时间维度的指标，提出基于时空维度的客流拥堵风险等级评价方法，通过风险概率值对车站内可能的拥挤区域进行动态识别。以广州地铁杨箕换乘枢纽站为例进行仿真建模，结果表明，优化后拥堵风险降低，服务水平提高，验证了上述方法的可靠性和实用性。
Abstracts:
Reasonable assessment of the risks of passenger flow congestion at urban rail transit station is of great importance for station safety operation and management. Based on the existing service level standards and combined with the density distribution, velocity distribution and traffic flow, a method to discriminate the crowded area is put forward. By introducing time dimension indicators such as the specified density and the duration of time, a traffic congestion risk grade evaluation method based on spatial-temporal dimension is put forward, and risk probability value is used for the dynamic identification of the crowded area within the station. Finally, Yangji transfer hub station in Guangzhou metro is taken as an example for the modelling simulation, and the result shows that the congestion risk is reduced, service level is raised after the improvement of station space, the reliability and practicability of the proposed method is verified.
