摘要: 针对自适应巡航控制(adaptive cruise control, ACC)车辆跟驰模型存在的不足,提出基于非线性动态车头间距的ACC跟驰模型,并分析模型特性。应用随速度非线性动态变化的车头间距策略,建立基于非线性动态车头间距策略的ACC跟驰模型,从交通流均衡态与非均衡态两个层面,分析所提模型在通行能力提升与跟驰模型稳定性两个方面的特性,并与以往模型进行对比分析。研究结果表明:所提ACC跟驰模型能够有效提升道路通行能力,同时具备良好的模型稳定性,可为ACC建模研究提供模型参考。

Abstract: According to the shortcomings of adaptive cruise control (ACC) vehicular car-following modeling, a new ACC car-following model based on nonlinear dynamic headway was proposed and its characteristics were also analyzed. Based on the nonlinear dynamic headway strategy changing with the speed, the ACC car following model based on nonlinear dynamic headway strategy was established. From two perspectives of equilibrium and non-equilibrium states of traffic flow, the characteristics of the proposed model in traffic capacity improvement and car following model stability were analyzed, and compared with those of the previous models. The study results show that the proposed ACC car-following model can effectively enhance the traffic capacity of road and has good model stability, which can provide model reference for ACC modeling research.

Key words: traffic and transportation engineering, car-following model, adaptive cruise control, traffic capacity, stability
