The invention discloses a networked vehicle following model and traffic flow stability analysis method, and relates to the technical field of intelligent traffic systems, and the method comprises the steps: introducing a time-varying expected interval based on an adaptive cruise control model ACC and a collaborative adaptive cruise control model CACC, and obtaining a TV-ACC and a TV-CACC following model; based on the TV-ACC car-following model and the TV-CACC car-following model, respectively obtaining a homogeneous traffic flow stability constraint discriminant value and a heterogeneous traffic flow stability discriminant value; analyzing the stability of the mixed traffic flow according to the homogeneous traffic flow stability constraint discriminant value and the heterogeneous traffic flow stability discriminant value; by overcoming the defects of collision, reversing, large speed fluctuation amplitude and the like of an original model, the speed of a subsequent vehicle is more gentle and more practical.

    本发明公开一种网联车跟驰模型与交通流稳定性分析方法,涉及智能交通系统技术领域,本方法包括:基于自适应巡航控制模型ACC、协同自适应巡航控制模型CACC引入时变期望间距,分别得到TV‑ACC和TV‑CACC跟驰模型;基于TV‑ACC跟驰模型与TV‑CACC跟驰模型,分别得到同质交通流稳定性约束判别值以及异质交通流稳定性判别值;根据同质交通流稳定性约束判别值和异质交通流稳定性判别值对混合交通流的稳定性进行分析;通过克服原模型存在的撞车、倒车和速度波动幅度较大等不足,使其后续车辆速度更加平缓且更符合实际。
