Data for: Rule compliance and desire lines in Barcelona’s cycling network

A major challenge in the development of new cycling infrastructure is the design of intersections that are safe, appropriately used, and inclusive. In this paper we study how cyclists interact with existing street design at intersections in Barcelona. We observed rule compliance (n = 5,063) and desire lines (n = 5,082) at six intersections over 12 weekdays. We find that 78.9% of cyclists comply with intersection rules, and that female cyclists are more likely to comply. Rule incompliance is associated with the gender of the cyclists, the directionality of the bike lanes that intersect, traffic signals, and performing a turn. Our analysis of desire lines through the intersections illustrate that incompliant behaviour is driven by a need for uninterrupted travel. We suggest ways to improve intersection design and safety: i) prioritise unidirectional bike lanes; ii) optimise traffic lights, and; iii) anticipate cyclists’ desired trajectories when designing new cycling infrastructure.新型自行车交通基础设施建设的一大核心挑战，在于设计出安全、使用合理且具备包容性的交叉口。本研究聚焦巴塞罗那境内交叉口处骑行者与既有道路设计的交互行为。研究团队在12个工作日内，对6处交叉口的骑行者规则遵守行为（有效样本量n=5,063）与意愿轨迹（desire lines，有效样本量n=5,082）开展了观测。研究结果显示，78.9%的骑行者会遵守交叉口通行规则，且女性骑行者的规则遵守率更高。骑行者的规则违规行为与骑行者性别、相交自行车道的通行方向性、交通信号灯设置以及转弯行为存在关联。对交叉口处意愿轨迹的分析表明，违规行为的核心动因是骑行者对不间断通行的需求。据此，本研究提出三类优化交叉口设计与安全性的改进方案：其一，优先采用单向自行车道；其二，优化交通信号灯配置；其三，在新型自行车交通基础设施设计阶段，预先考量骑行者的意愿通行轨迹。
