论文摘要
混合交通区域的建模和模拟是运输规划人员评估未来城市地区安全，效率和人类友好性的重要工具。本文将现有共享空间模型的校准问题和可转移性问题应用于文化方面，交通状况和空间布局方面的方案。特别是，这项工作的第一个贡献是通过通用方法来增强游戏理论社会力量模型（GSFM），用于很大程度上自动化模型校准。我们说明了德国共享空间环境的校准方法的使用。第二个贡献是研究共享空间模型的可传递性。我们定义了模型可传递性的标准，并提出了一个案例研究，其中我们根据``德国数据集''构建的模型的可传递性分析和评估了与中国不同共享空间环境的模型。我们的研究结果表明，尽管（可以预期）该模型面临难以通过在我们的模型中添加该环境的社会规范（通过分析得出）来复制道路使用者的运动行为，但可以通过有限的努力获得令人满意的模型准确性提高。
Modelling and simulation of mixed-traffic zones is an important tool for transportation planners to assess safety, efficiency, and human-friendliness of future urban areas. This paper addresses problems of calibration and transferability of existing shared space models when applied to scenarios that differ in terms of cultural aspects, traffic conditions, and spatial layout. In particular, the first contribution of this work is an enhancement of the Game-Theoretic Social Force Model (GSFM) by a generic methodology for largely automated model calibration; we illustrate the use of the calibration method for a shared space environment in Germany. The second contribution is an investigation into transferability of shared space models. We define criteria for model transferability and present a case study, in which we analyse and evaluate transferability of the model we constructed based on the ``German dataset'' to a different shared space environment from China. Our results indicate that although -- as to be expected -- the model faces difficulties to replicate the movement behaviours of road users from a new environment, by adding social norms (derived through analysis) of that environment to our model, satisfactory improvement of model accuracy can be obtained with limited effort.
