Abstract

Cycling levels in cities keep increasing, which is accompanied with more cyclists being involved in serious road crashes. This paper aims to contribute to safer urban cycling by examining risk factors associated with cycling in the four largest Dutch cities, incorporating spatial and temporal variations in bicycle crash risk. For this purpose, the crashes and exposure metrics are analysed on an hourly temporal resolution. The results reveal that utilising an hourly temporal resolution in the exposure metrics and bicycle crash risk gives more detailed results compared to daily averages of these metrics. Moreover, the exposure to cyclists and motorised vehicles both have a significant impact on bicycle crash risk. The results also imply that separating cyclists from high-speed motorised vehicles might be more important than implementing a lower speed limit to curb the increasing severity of crashes. Despite some local differences, the overall results of the risk factors are remarkably similar across the cities, providing increased generalisability and transferability of the study. The findings indicate that concerns about the effects of increasing bicycle use and large flows of motorised vehicles on bicycle crash risk are valid, showing the importance of efforts towards improving bicycle safety in cities.
通过考虑暴露的时空分解来检查与骑自行车相关的撞车风险因素:来自四个荷兰城市的调查结果
城市中骑自行车的人数不断增加,与此同时,越来越多的骑自行车的人卷入了严重的道路交通事故。本文旨在通过研究荷兰四大城市中与骑行相关的风险因素,结合自行车碰撞风险的时空变化,为更安全的城市骑行做出贡献。为此,崩溃和曝光指标按小时时间分辨率进行分析。结果表明,与这些指标的每日平均值相比,在暴露指标和自行车碰撞风险中利用每小时的时间分辨率可以获得更详细的结果。此外,接触自行车和机动车对自行车碰撞风险都有显著影响。研究结果还表明,为了遏制日益严重的撞车事故,将骑自行车的人与高速机动车辆分开可能比实施更低的速度限制更重要。尽管存在一些地方差异,但风险因素的总体结果在各个城市之间非常相似,这增加了研究的普遍性和可转移性。研究结果表明,人们对自行车使用量增加和机动车大量流动对自行车碰撞风险的影响的担忧是有效的,这表明了努力提高城市自行车安全的重要性。
