当街道按照共享空间的原则进行设计时，鼓励道路使用者自发地进行互动，以协商空间。这些相互作用机制不遵循明确定义的交通规则，而是与安全、舒适和时间压力有关的心理和社会原则。然而，这些规律很难捕捉和量化，因此很难模拟道路使用者的行为。本文研究了行人与机动车之间的交通冲突情况，主要目的是建立一个离散选择模型，以确定合适的冲突解决策略。以德国汉堡的一条人流量较大的共享空间街道为例，进行了模型的建立和标定。冲突情况通过轨迹预测和比较的自动过程来检测。通过观察行为模式，确定行人和车辆的标准回避行为。制定了一组可能影响回避动作选择的潜在参数，并对其进行了意义测试。这些包括几何方面，如冲突用户的距离和速度，以及特定于冲突的方面，如碰撞时间。最后对多项式Logit模型进行了标定，并在实际中进行了验证。所开发的方法是现实的，并准备好在共享空间或任何其他组织较少的交通环境的运动模型中实施。
When streets are designed according to the shared space principle, road user are encouraged to interact spontaneously with each other for negotiating the space. These interaction mechanisms do not follow clearly defined traffic rules but rather psychological and social principles related to aspects of safety, comfort and time pressure. However, these principles are hard to capture and to quantify, thus making it difficult to simulate the behavior of road users. This work investigates traffic conflict situations between pedestrians and motorized vehicles, with the main objective to formulate a discrete choice model for the identification of the proper conflict solving strategy. A shared space street in Hamburg, Germany, with high pedestrian volumes is used as a case study for model formulation and calibration. Conflict situations are detected by an automatic procedure of trajectory prediction and comparison. Standard evasive actions are identified, both for pedestrians and vehicles, by observing behavioral patterns. A set of potential parameters, which may affect the choice of the evasive action, is formulated and tested for significance. These include geometrical aspects, like distance and speed of the conflicting users, as well as conflict-specific ones, like time to collision. A multinomial logit model is finally calibrated and validated on real situations. The developed approach is realistic and ready for implementation in motion models for shared space or any other less organized traffic environment.
