This research aims to understand how changing characteristics of surface conditions during winter influence the walking experience and convenience. For this purpose, we have observed and measured naturalistic walking behaviour (n = 1551) in terms of step lengths and step frequencies on various surface conditions typically associated with winter environments. The results show that step lengths are significantly reduced on snow- and ice-covered surfaces compared to asphalt. Step frequencies are significantly increased on ice compared to asphalt. These changes in walking behaviour are likely done to increase stability and reduce the risk of falling on slippery surfaces. However, a possible effect of these alterations in walking behaviour might be that energy consumption of walking is increased. This might increase exhaustion, be deemed less attractive, and likely reduces acceptable walking distances during winter. Improved winter operation can compensate for some of the negative effects.

这项研究旨在了解冬季地面条件的变化特征如何影响步行体验和便利性。为此，我们观察并测量了自然行走行为（n = 1551）在与冬季环境相关的各种路面条件下的步长和步频。结果显示，与沥青路面相比，冰雪覆盖路面上的步长明显缩短。与沥青路面相比，冰面上的步频明显增加。行走行为的这些变化很可能是为了增加稳定性，降低在湿滑路面上跌倒的风险。然而，这些行走行为的改变可能会导致行走的能量消耗增加。这可能会增加疲惫感，降低吸引力，并可能减少冬季可接受的步行距离。改善冬季运行状况可以弥补一些负面影响。
