行人速度对于设计信号配时以及理解行人安全问题至关重要。本文分析了卡塔尔三条信号人行横道上的三种行人速度（入口速度、过马路速度和出口速度）。使用trafficanalyzer软件跟踪行人的运动，并分析数据以确定信号指示、人行横道长度和人行横道方向对行人速度的影响。分析结果表明，在行人绿灯或行人闪绿灯间隔期间，只有23.69%的行人合法过马路。此外，行人进入速度受行人信号指示的显著影响。绿灯和红灯指示下行人的通行速度与人行横道长度正相关，行人出口速度与人行横道长度无关，但受人行横道方向影响显著。
Pedestrian speed is essential for designing signal timings as well as for understanding pedestrian safety issues. This paper presents analysis of three types of pedestrian speeds (entry speed, crossing speed, and exit speed) at three signalized crosswalks in the State of Qatar. Pedestrian movements were tracked usingTrafficAnalyzersoftware and data were analyzed to determine the effect of signal indications, crosswalk length, and crossing direction on pedestrian speeds. The results of this analysis showed that only 23.69% pedestrians crossed legally, during pedestrian green or pedestrian flashing green interval. Moreover, the pedestrian entry speeds were significantly affected by the pedestrian signal indications. Furthermore, the crossing speeds were positively correlated with crosswalk length for pedestrians crossing on green and red indications while pedestrian exit speeds were independent of crosswalk length but significantly affected by crossing direction.
