The European Union is in the process of abolishing the bi-annual clock change. Against this backdrop, we analyze how daylight and twilight affect the sustainable transport mode of cycling, and find that better daylight conditions generally lead to higher levels of cycling. The extent of this effect depends on the type of traffic and the time of day. An all-year implementation of Daylight Saving Time would then lead to an increase in overall cycling levels of around 3.14 %-3.37 %, compared to an all-year Standard Time. This would imply an increase of around 1.27-1.36 billion cycled kilometers per year in Germany alone. Additionally, we provide monetary estimates for the external effects of such changes in cycling levels.
欧盟正在废除一年两次的时钟调整。在此背景下，我们分析了日光和曙光如何影响可持续的骑行交通方式，并发现更好的日光条件通常会带来更高的骑行水平。这种影响的程度取决于交通类型和一天中的时间。与全年采用标准时间相比，全年实行夏令时将使总体骑行水平提高约3.14%-3.37%。仅在德国，这就意味着每年骑行公里数将增加约12.7-13.6亿公里。此外，我们还对骑行水平变化的外部影响进行了货币估算。
