许多研究使用调查来调查步行或骑自行车的人对照明变化的反应。另一种方法是使用客观数据，特别是在不同照明条件下存在的行人和骑自行车者的数量。这些数据以前曾使用夏令时过渡方法报告过。本文提出了一种不同的方法来分析环境光条件的影响，其中全年的数据进行检查，而不是只有两个星期的每一方的一年两次的夏令时时钟的变化。结果证实，环境光有显着的影响：对于一天中的给定时间，更多的人步行或骑自行车时，它是白天比天黑后，更多的人骑自行车在自行车道上，走在人行道上天黑后，当他们被照亮时，比当他们没有被照亮。虽然这两种方法都使用比值比方法，该方法应考虑照明以外的环境变化，但结果表明，日光节约分析方法比全年方法更好地将天气变化与环境光对旅行选择的影响隔离开来。
Many studies have used surveys to investigate the reactions to changes in lighting from people who walk or cycle. An alternative approach is to use objective data, specifically the number of pedestrians and cyclists present under different lighting conditions. Such data have been reported previously using a daylight savings transition approach. This paper presents a different method for analysing the effect of ambient light conditions in which data from the whole year are examined, rather than only the two weeks either side of the biannual daylight savings clock changes. The results confirm that ambient light has a significant impact: For a given time of day, more people walk or cycle when it is daylight than after dark and more people cycle on cycle trails and walk on foot paths after dark when they are lit than when they are unlit. While both methods use an odds ratio approach, which should account for environmental changes other than lighting, the results suggest the daylight savings method of analysis better isolates changes in weather from the effects of ambient light on travel choice than does the whole-year method.
