本文对文献[R]提出的非局部宏观行人流模型进行了修正。科伦坡先生,加拉维洛先生,和拉西埃先生。一类行人交通的非局部模型。数学。模型、方法、应用。科学。[j], 22(4): 1150023,2012]来解释各向异性相互作用以及行走区域中墙壁或其他障碍物的存在。我们证明了该扩展模型的适定性,并采用高分辨率数值格式来说明模型的特征。特别是,数值模拟突出了不同模式参数在观测到的模式形成中的作用。
This study revises the non-local macroscopic pedestrian flow model proposed in [R. M. Colombo, M. Garavello, and M. Lécureux-Mercier. A class of nonlocal models for pedestrian traffic. Math. Models Methods Appl. Sci., 22(4):1150023, 2012] to account for anisotropic interactions and the presence of walls or other obstacles in the walking domain. We prove the well-posedness of this extended model and we apply high-resolution numerical schemes to illustrate the model characteristics. In particular, numerical simulations highlight the role of different model parameters in the observed pattern formation.
