Summary
This review paper investigates the impact of weather conditions on bicycle risk exposure, defined primarily through traffic volume. The research is motivated by the fact that cyclists are vulnerable road users whose travel decisions are highly sensitive to weather, unlike motorized drivers. Since traffic volume is a key independent variable in road safety models, understanding how weather influences bicycle usage is critical for accurate crash prediction and infrastructure planning. The study aims to identify which weather parameters significantly affect bicycle volume, quantify these effects, and determine factors that differentiate these impacts across various contexts. The methodology consists of a comprehensive literature review of 33 papers published between 1977 and 2020, sourced from Web of Science, Scopus, and TRID databases. The reviewed studies varied in geography, methodology (surveys vs. empirical counter data), and cyclist demographics. The author synthesized these findings to evaluate the qualitative and quantitative impacts of weather on bicycle use and utilized previous research results alongside own road safety models to estimate the consequent effect on predicted cyclist crashes. The results demonstrate that air temperature, precipitation, sunshine, cloud cover, humidity, and wind strength significantly influence bicycle volume. Specific findings include that heavy rain can deter 13–50% of cyclists, while ideal temperatures for cycling range from 25°C to 28°C. The impact of weather varies significantly by cyclist group; recreational cyclists are more sensitive to weather than commuters, and females and younger cyclists are more sensitive than males and older cyclists. Additionally, the influence of weather differs by location and climate zone. For instance, in some contexts, temperature had a stronger correlation with recreational cycling than commuting. The study also notes that forecasted weather affects cycling decisions similarly to actual conditions. The significance of this research lies in highlighting the complexity and sensitivity of the relationship between weather and bicycle risk exposure. The findings imply that weather conditions must be explicitly accounted for in road safety analyses, traffic volume estimations, and infrastructure design to ensure accurate comparisons across different locations and time periods. Ignoring these variables can lead to flawed safety assessments and inefficient planning. The paper concludes by recommending that future research continue to explore these dynamics, particularly considering climate change and varying transportation cultures, to improve the safety and accessibility of cycling infrastructure.
