共享空间是一种创新的街景设计，力求车辆交通和行人之间的距离最小化。城市设计正在走向空间共享，以此作为增强街道环境社区质感的一种手段。其独特的功能旨在平衡优先事项，让汽车和行人和谐共处，而无需规定行为。然而，需要一种模拟工具来对未来的共享空间方案进行建模，并帮助判断它们是否可以代表传统街道布局的合适替代方案。本文以作者之前发表的作品为基础，其中提出了基于社会力模型 (SFM) 的共享空间微观混合交通模型，并使用来自英国布莱顿新路共享空间链接类型的数据进行了校准和评估。在这里，我们的目标是探索作者模型到类似共享空间类型的可移植性，并研究流量和交通模式比率的影响。收集并分析了伦敦展览路共享空间方案记录的数据。展览路的车流、速度以及行人和汽车之间的隔离比新路更大。用于共享空间建模的基于规则的 SFM 已使用真实数据进行校准和验证。根据结果，可以得出结论，共享空间方案是依赖于环境的，环境的基础设施设计以及行人和车辆的流量和速度等因素会影响共享空间的意愿。
Shared space is an innovative streetscape design that seeks minimum separation between vehicle traffic and pedestrians. Urban design is moving toward space sharing as a means of increasing the community texture of street surroundings. Its unique features aim to balance priorities and allow cars and pedestrians to coexist harmoniously without the need to dictate behavior. There is, however, a need for a simulation tool to model future shared space schemes and to help judge whether they might represent suitable alternatives to traditional street layouts. This paper builds on the authors’ previously published work in which a shared space microscopic mixed traffic model based on the social force model (SFM) was presented, calibrated, and evaluated with data from the shared space link typology of New Road in Brighton, United Kingdom. Here, the goal is to explore the transferability of the authors’ model to a similar shared space typology and investigate the effect of flow and ratio of traffic modes. Data recorded from the shared space scheme of Exhibition Road, London, were collected and analyzed. The flow and speed of cars and segregation between pedestrians and cars are greater on Exhibition Road than on New Road. The rule-based SFM for shared space modeling is calibrated and validated with the real data. On the basis of the results, it can be concluded that shared space schemes are context dependent and that factors such as the infrastructural design of the environment and the flow and speed of pedestrians and vehicles affect the willingness to share space.
