Abstract

It is a big challenge to generate the traffic scenarios with frequent lane changes in flow-based continuum traffic simulations. In this paper, we present a novel macroscopic method, named interactable cooperative driving lattice hydrodynamic model (Interactable CDL-H model). We describe traffic flow along lanes and flow interactions between lanes in a uniformly continuum frame. We further consider various constraints for a detailed lane-changing simulation. The model owns the efficiency of traditional macroscopic traffic models and can describe lane-changing behaviors effectively. It physically describes where/when/how traffic flow goes into (out) of a lane, which make it possible to simulate and display lane-changing behaviors in large-scale virtual environments. The validity and efficiency of the interactable CDLH model are demonstrated by comparing simulation results with real traffic data and one-dimensional CDLH model.
在连续流量中建模交互
在基于流的连续交通模拟中,如何生成频繁变道的交通场景是一个很大的挑战。本文提出了一种新的宏观方法,称为交互协同驱动晶格流体动力学模型(交互CDL-H模型)。在均匀连续的框架中描述了沿车道的交通流和车道间的交通流相互作用。我们进一步考虑了详细变道模拟的各种约束条件。该模型具有传统宏观交通模型的效率,能够有效地描述变道行为。它从物理上描述了交通流进入(出)车道的地点/时间/方式,这使得在大规模虚拟环境中模拟和显示变道行为成为可能。通过将仿真结果与实际交通数据和一维CDLH模型进行比较,验证了交互式CDLH模型的有效性和有效性。
