英国的研究显示,对于老年人来说,标准人行道时间太短,敦促在信号设计方面放慢行走速度。 UK study reveals standard crosswalk times are too short for older adults, urging slower walking speeds in signal design.

联合王国的一项研究发现,对于老年人和有流动问题的人来说,标准行人过境时间太短,平均步行速度为0.77米/秒——远低于设计所用的1.2米/秒——需要6.5秒才能通过5米长的道路,比典型的绿色信号长2秒钟。 A UK study finds standard pedestrian crossing times are too short for older adults and people with mobility issues, with average walking speeds of 0.77 m/s—well below the 1.2 m/s used in design—requiring 6.5 seconds to cross a five-meter road, over two seconds longer than typical green signals. 在接受研究的老年人中,只有1.5%能够在标准期限内安全过境。 Only 1.5% of older adults studied could cross safely within standard durations. 研究人员建议将信号时间调整到0.7m/s,以改善安全、独立和体育活动,敦促更新城市设计,支持更健康的老龄化。 Researchers recommend adjusting signal timing to 0.7 m/s to improve safety, independence, and physical activity, urging updated urban design to support healthier aging.
