在一维元胞自动机交通流WWH模型和SDNaSch模型的基础上,建立了一种考虑驾驶员特性的元胞自动机交通流模型(Driver-SDNaSch模型).该模型将驾驶员分为激进型、保守型和中立型三类,根据其不同的驾驶特性制定了各自的演化规则,并以此对其进行状态更新;同时考虑了前车速度为0的情况,引入安全减速概率.通过计算机对Driver-SDNaSch模型进行模拟,给出了由三类驾驶员按不同比例组成的混合交通流的速度-密度图和流量-密度图,并对此类混合交通流的特性进行了分析和讨论.与NaSch模型和SDNaSch模型相比,Driver-SDNaSch模型减少了车辆流的堵塞现象,提高了道路的通行能力.
Based on the one-dimensional cellular automata WWH model and the SDNaSch model, a cellular automata traffic flow model (Driver-SDNaSch model) considering the characteristics of the driver is established. The model divides the driver into radical , Conservative and neutral type, according to their different driving characteristics to develop their own evolution rules, and thus its status update; also consider the situation in front of the vehicle speed is 0, the introduction of safety deceleration probability. By computer pairs Driver-SDNaSch model, the velocity-density maps and flux-density maps of mixed traffic flow composed of three types of pilots are given, and the characteristics of such hybrid traffic flows are analyzed and discussed. Compared with SDNaSch model, Driver-SDNaSch model can reduce the congestion of vehicle flow and improve the traffic capacity of the road.
