At non-signalized mid-block street crossings in China's cities, pedestrians often weave between motor vehicle flows. This paper investigated the influence patterns of the gender and age of pedestrians, the presence of a pedestrian group, vehicles' interference and the crossing direction on the crossing time at non-signalized mid-block street crossings in Changsha, China. The results show that the crossing speed is approximately 1-1.1 m/s; the crossing time increases with increasing age, and the crossing speed of a pedestrian will be quicker when the time gap between the pedestrian and the oncoming vehicle is smaller if he/she decides to cross. This paper also analyzed the crossing time pattern when pedestrians cross lane by lane and found that pedestrians spend the most time crossing the first lane and the least time crossing the middle lane, regardless of whether they are crossing from the curb to the central island or from the central island to the curb. The crossing speed is an important input to the design of pedestrian facilities, so these findings can be applied to the assessment of pedestrian crossing safety in China's cities and can provide a basis for the design of pedestrian crossing facilities.The 85th percentile pedestrian crossing times for sites 1, 2 and 3 are 4.8, 4.6 and 4.7 s, respectively, corresponding to speeds of 0.73, 0.76 and 0.74 m/s. The 15th percentile pedestrian crossing speed is an important parameter. The Manual on Uniform Traffic Control Devices of the United States [24] offers a specification: when the 15th percentile pedestrian crossing speed is below 1.1 m/s, a signal control is not necessary. The surveyed point has no signal control for pedestrian crossing, which accords with this specification.
The influence of pedestrian attributes on the crossing timeDifferences in thinking exist between males and females, and people's physical ability varies with age. This section investigates the influence of gender and age on crossing time.
