Abstract:

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.

Key words: engineering of comunications and transportation system, urban rail transit, exiting passenger, queuing mechanism
