An advanced design classification system for bicycle paths, based on geometric features and force equilibrium, can pave the way for improved bicycle safety, accident prevention and the development of design guidelines. A design and classification system does exist for bicycle paths, but the number of accidents has led to ambivalence about its validity and effectiveness. In addition, a universally accepted classification system has not yet been approved or adopted. This paper presents a unique set of design parameters, analytically developed based on formulas that consider the physical characteristics and dimensions of individual bicycles. The proposed design system is based on theoretical trigonometric derivations. The model was validated with the real-world geometry of the transportation infrastructure of the city of Antwerp, Belgium. The conclusions of this study are useful for evaluating the effectiveness of bicycle paths during the design stage without the necessity for real-world experiments. The results will thus be valuable for stakeholders working on policy frameworks, bicycle safety and riding comfort.

自行车道的解析几何设计

基于几何特征和力平衡的先进的自行车道设计分类系统可以为改善自行车的安全性，预防事故和制定设计准则铺平道路。确实存在针对自行车道的设计和分类系统，但是事故的数量导致人们对其有效性和有效性产生歧义。另外，尚未批准或采用普遍接受的分类系统。本文介绍了一组独特的设计参数，这些参数是根据考虑了各个自行车的物理特性和尺寸的公式进行分析开发的。所提出的设计系统基于理论三角推导。该模型已通过比利时安特卫普市交通基础设施的实际几何结构进行了验证。这项研究的结论对于在设计阶段评估自行车道的有效性很有用，而无需进行实际实验。因此，这些结果对于制定政策框架，自行车安全性和骑行舒适性的利益相关者而言将是有价值的。
