基于分子跟驰特性的交通流局部稳定性分析

交通流稳定性分析是交通流特性分析的重要组成部分,对解析交通流运行规律具有重要的理论价值.运用分子动力学,系统解析交通流的分子跟驰特性,对处于稳定运行状态下的同步流车队进行局部稳定性分析,并建立车辆跟驰的局部稳定性模型和扰动波能量定量模型,利用Matlab软件对模型进行数值仿真分析,结果表明对于一个处于稳定状态下的同步流车队,跟随车在受到相邻前导车的扰动后能否保持原运行状态与车辆受到的扰动波能量δ大小有关.

Stability of the local analysis of the traffic flow based on the molecular-following behavior

Traffic flow stability analysis is an important component of the analysis of the char- acteristics of traffic flow. It is of great theoretical value significance to parse traffic flow op- eration rules. This article discusses of traffic flow molecules with following characteristics, and the local stability of the synchronized flow fleet under the steady-state movement, estab- lishes the stability of motion-following vehicles model and the disturbance wave energy quan- titative models, and analyzes numerical simulation conclusions by using Matlab, which is based on the traffic molecular dynamics. The results show that the car following to be able to maintain the original steady-state driving vehicle, the disturbance depends on the wave en- ergy by the size of the disturbance by adjacent leading vehicle.
