This research examines whether Beijing residents are more or less likely than Montréal residents to avoid stair climbing, by replicating a study in Montréal, Canada that measured the impacts of distance between stairs and escalator, height between floors and pedestrian volume on stair climbing rate.
15 stairways, 14 up-escalators and 13 down-escalators were selected in 13 publicly accessible settings in Beijing. Distance between the bottom or top of nearest stair and escalator combinations varied from 2.1 m to 114.1 m with height between floors varying from 3.3 m to 21.7 m. Simultaneous counts were conducted on stair and escalator pairs, for a total of 37,081 counted individuals.
In the ascent model, pedestrian volume accounted for 16.3% of variance in stair climbing, 16.4% when height was added and 45.1% when distance was added. In the descent model, 40.9% of variance was explained by pedestrian volume, 41.5% when height was added and 45.5% when distance was added.
Separating stairs and escalator is effective in increasing stair climbing in Beijing, accounting for 29% of the variance in stair climbing, compared with 43% in Montreal. As in the Montreal case, distance has less effect on stair use rate when descending. Overall, 25.4% of Beijingers opted for stairs when ascending compared with 20.3% of Montrealers, and for descending 32.8% and 31.1% respectively.
通过重复加拿大蒙特利尔的一项研究,该研究测量了楼梯与自动扶梯之间的距离、楼层高度和行人流量对爬楼梯率的影响,来研究北京居民比蒙特利尔居民更有可能还是更不可能避免爬楼梯。
在北京13个公共场所选取了15个楼梯、14个上行自动扶梯和13个下行自动扶梯。最近的楼梯与自动扶梯组合的底部或顶部之间的距离在2.1米至114.1米之间,楼层高度在3.3米至21.7米之间。对楼梯和自动扶梯对进行同步计数,总共统计了37081个人。
在上行模型中,行人流量占爬楼梯差异的16.3%,加入高度因素后占16.4%,加入距离因素后占45.1%。在下行模型中,行人流量解释了40.9%的差异,加入高度因素后占41.5%,加入距离因素后占45.5%。
在北京,将楼梯和自动扶梯分开对增加爬楼梯行为是有效的,占爬楼梯差异的29%,而在蒙特利尔为43%。与蒙特利尔的情况一样,下行时距离对楼梯使用率的影响较小。总体而言,25.4%的北京人在上行时选择楼梯,而蒙特利尔人这一比例为20.3%,下行时分别为32.8%和31.1%。
