摘要
在实测数据的基础上,分析了轨道交通出站乘客的出站规律,拟合了出站乘客在通道内和楼梯上的流量-密度曲线。在所得流量-密度曲线的基础上,研究了两个不同出站通道宽度条件下楼梯处乘客的排队机理。研究表明,拥堵产生时,通道和楼梯上乘客的水平速度近似相等,但楼梯上乘客的密度小于通道内乘客的密度,楼梯的通行能力低于通道的通行能力,从而产生乘客排队现象。
Based on the surveyed data,the arrival behavior of the exiting passengers and the relationship between the pedestrian flow and the density in the passage and at the stariway have been analyzed.According to the regressed flow-density curve,the queuing mechanism of the passenger at the exit stairway was studied when the passage has the two different widths relative to the stairway.It was showed that the horizontal speed of the passenger at stairway is approximately equal to that in the passage wheu the jam occurs,but the passenger density at the stairway is lower tham that in the passage.The capacity of the stairway is lower than that of the passage,thus the queue occurs.
