Stair-riser banners are twice as effective as posters in encouraging stair climbing in shopping centres. This study tested the effectiveness of stair-riser banners in an English train station in 2006-2007.
The train station had a 39-step staircase and an adjacent escalator. Baseline observations (3.5 weeks) were followed by 10.5 weeks of a banner intervention supplemented with 3 weeks of a poster intervention. Both poster and banner featured the message 'Stair climbing burns more calories per minute than jogging. Take the stairs'. Ascending escalator and stair users (N=36,239) were coded for gender.
Analyses, controlling for effects of gender and pedestrian traffic volume, revealed no significant change in stair climbing between baseline (40.6%) and the banner intervention (40.9%; p=0.98). Addition of the poster increased stair climbing (44.3%; OR=1.36, 95% CIs 1.16-1.60, p<0.001), with the effect reduced at higher pedestrian traffic volumes.
While stair-riser banners had no effect, the poster intervention increased stair climbing. The high pedestrian volumes as the wave of disembarking passengers seek to leave the station would have obscured the visibility of the banner for many commuters. Thus stair-riser banners appear unsuitable point-of-choice prompts in stations where pedestrian traffic volume is high.
在购物中心，楼梯踏步横幅在鼓励人们爬楼梯方面的效果是海报的两倍。本研究于2006 - 2007年在英国一个火车站测试了楼梯踏步横幅的效果。
该火车站有一个39级的楼梯和一部相邻的自动扶梯。在进行了3.5周的基线观察后，进行了10.5周的横幅干预，并辅以3周的海报干预。海报和横幅都展示了“爬楼梯每分钟燃烧的卡路里比慢跑还多。请走楼梯”这一信息。对乘坐自动扶梯和楼梯的乘客（N = 36239）按性别进行编码。
在控制了性别和行人流量的影响后进行分析，结果显示在基线阶段（40.6%）和横幅干预阶段（40.9%），爬楼梯的人数没有显著变化（p = 0.98）。增加海报后，爬楼梯的人数有所增加（44.3%；OR = 1.36，95%置信区间为1.16 - 1.60，p < 0.001），在行人流量较大时，这种效果会减弱。
虽然楼梯踏步横幅没有效果，但海报干预增加了爬楼梯的人数。随着大批下车乘客试图离开车站，高行人流量会使许多通勤者看不到横幅。因此，在行人流量大的车站，楼梯踏步横幅似乎不是合适的选择提示点。
