以元胞自动机理论为基础,建立了一种新型分级高速公路元胞自动机能耗动力学模型。并以分级路段组成的青兰高速公路为例,进行了交通流仿真,分析了最大速度、分级路况下的车辆慢化概率对通行能力及交通流能耗的影响,分析了优等、劣等路段的交通流状况与整个分级高速公路系统交通流状况之间的关系,得到相应的定量分析结论。通过对分级高速公路能耗进行仿真与分析,为高效运营和管理分级高速公路提供了科学的理论依据。
In this case, the paper presents an improved energy consumption of highway grading sections cellular automaton model based on FI traffic model. The improved cellular automaton model is used for highway traffic flow simulation. Then, the influence of the highway maximum speed and the graded road (vehicle deceleration probability) on the capacity and traffic flow energy consumption will be analyzed. Research on complex characteristics of QingLan highway traffic system for example by modeling and simulation so as to provide scientific theory for the highway traffic Operation and management later.
