在交通道路设计领域，共享空间方法旨在将道路从单纯的交通基础设施发展为公共空间，迫使道路使用者之间进行更高程度的互动。在本文中，我们开发的基础上的社会力量模型的微观仿真工具，以代表道路使用者在这样的布局的运动。通过对布伦瑞克市（D）一个交通便利的十字路口中的用户行为的观察，建立了一个多层结构模型，其中每一层都被指定用于处理不同的情况，从自由流动到拥挤情况下的用户交互。能见度图和回旋估计用于设计道路使用者的自由流动运动的轨迹。此外，经典的社会力模型的增强，以模拟远程避碰行为。最后，通过两个观察到的场景，其中包括行人和汽车之间的各种冲突，增强的仿真框架进行了验证。
In the field of traffic road design, the shared space approach aims to develop roads from mere traffic infrastructures to public spaces, compelling higher interaction between road users. In this paper we develop the fundamentals for a micro-simulation tool based on the Social Force Model, to represent the motion of road users in such layouts. Working with the observed behavior of users in a pedestrian-friendly intersection in the city of Braunschweig (D), a multi-layer structured model is developed, in which each layer is designated to handle different situations, from free-flow movements to user interactions in crowded situations. Visibility graphs and clothoid estimations are used for designing trajectories of road users for the free flow movement. Furthermore, an enhancement of the classical Social Force Model is provided in order to model long-range collision avoidance behavior. Finally, the enhanced simulation framework is validated by two observed scenarios, which include various conflicts between pedestrians and cars.
