当根据共享空间原则设计街道时,道路使用者往往会自发地互动,并通过调整其轨迹和速度来协商彼此的优先权。尽管近年来这种设计原则取得了成功,但交通工程师仍然不能依赖于共享空间的微观仿真工具,这对于计算描述交通安全和质量的性能指标非常有用。有鉴于此,作者在前期研究中开发了一个基于社会力的三层模型,能够模拟共享空间环境的运行。目前工作的目的是扩展该模型,包括多种冲突情况下的冲突解决策略,即,涉及两名以上道路使用者的冲突。提出了一种基于聚合概率的道路使用者行为策略确定方法。该模型的优点是通过观察到的情况下,涉及多个行人和驾车者。
When streets are designed according to the shared space principle, road users tend to interact spontaneously and to negotiate priority with each other by adapting their trajectory and speed. Despite the success of this design principle in the recent years, traffic engineers still cannot rely on microsimulation tools for shared spaces, which would be extremely useful to compute performance indicators describing safety and quality of traffic. In view of this, in the previous research the authors have developed a three-layered social force-based model, capable to simulate the operation of shared space environments. The aim of the current work is to extend the model by including conflict solving strategies for multiple conflict situations, i.e., conflicts which involve more than two road users. A methodological approach based on aggregated probabilities is proposed to determine road users’ behavioral strategy. The goodness of the model is shown by means of an observed situation involving multiple pedestrians and motorists.
