在开放性边界条件下,利用改进的Nagel Schreckenberg交通流模型,引入过路口车辆的可转向机理,建立二维n速主干道元胞自动机交通流模型,研究了转向概率和边界条件对干道交通状况的影响而导致的不同相变特性以及这两个因素对实现改善干道交通的组织作用.
Under the condition of open boundary, the improved Nagel Schreckenberg traffic flow model is introduced to introduce the steering mechanism of crossing vehicles, and a two-dimensional n-speed traffic flow cellular cellular automata model is established. The influence of steering probability and boundary conditions on traffic flow The different phase transition characteristics caused by the impact of the situation and the organizational effect of these two factors on the improvement of traffic flow in the trunk road.
