The improvement of evacuation efficiency for pedestrians mixed with wheelchair users has practical significance to public safety. In this study, a series of pedestrian experiments are performed in corridors considering assisted wheelchair users. It is observed that an able-bodied pedestrian’s unimpeded speed and relaxation time are 38.9% higher and 24.5% shorter than those of wheelchair users, respectively. The forward proxemic values of wheelchair users are smaller than their backward ones. However, both are larger than those of able-bodied participants. The presence of wheelchair users makes the pedestrian flow have a smaller density range (0.59–4.17m−2) and flow rate (1.49 0.21 (m s)−1). The critical headway and safe response time (reciprocal of the proportionality constant of the headway–speed relation) are 11.76% and 20.93% longer, respectively. The findings illustrate a lower efficiency and higher safety requirements for pedestrian flow including wheelchair users, which is valuable for simulation construction, facility design or evacuation guidance.

包括轮椅使用者在内的直廊行人流基本图

提高行人和轮椅使用者的疏散效率,对公共安全具有现实意义。在这项研究中,考虑到辅助轮椅使用者,在走廊中进行了一系列行人实验。据观察,身体健全的行人的畅通速度和放松时间分别比轮椅使用者高 38.9% 和短 24.5%。轮椅使用者的前向近似值小于后向近似值。然而,两者都比身体健全的参与者大。轮椅使用者的存在使得行人流具有较小的密度范围(0.59–4.17m -2)和流速(1.49 0.21 (ms) -1)。临界车头时距和安全响应时间(车头时距-速度关系的比例常数的倒数)分别长 11.76% 和 20.93%。研究结果表明,包括轮椅使用者在内的行人流具有较低的效率和较高的安全要求,这对于模拟施工、设施设计或疏散指导很有价值。
