考虑个性化驾驶员的信号口车速引导研究

A Study of Speed Guidance at Signal Gates Considering Individualized Drivers

车速引导系统的发展可以减少道路交通拥堵现象,保证行车安全,提高通行效率与燃油经济性,但针对个性化驾驶员的车速引导以及跟驰状态下的车速引导研究甚少,多为考虑单车的路口通行引导,且现有的车速引导系统研究中大多忽视不同驾驶风格的主观决策对车速引导的影响,车速引导系统缺乏广泛的适用性,难以满足不同类型驾驶员的需求。因此本文建立在对驾驶员驾驶风格分类的基础上,利用层次分析法(AHP)分别对不同风格的驾驶员进行路口通行时的决策倾向指标进行权重确定,将跟驰模型与车速引导相结合,优化跟驰模型,得出最优引导加速度,通过仿真得出优化曲线,研究表明,在考虑了个性化驾驶员的跟驰行为后的车速引导模型,能在保证一定的车辆通行效率的前提下,提高了安全性,更加符合现实驾车场景,具有一定的参考价值。

The development of speed guidance system can reduce road traffic congestion, ensure traffic safety, and improve traffic efficiency and fuel economy, but there is little research on speed guidance for individual drivers and speed guidance in the following state, mostly considering the intersection guidance of a single vehicle, and most of the existing speed guidance system research ignores the impact of subjective decisions of different driving styles on speed guidance, and the speed guidance system. The speed guiding system lacks wide applicability and is difficult to meet the needs of dif-ferent types of drivers. Therefore, this paper builds on the classification of drivers’ driving styles, uses the hierarchical analysis method (AHP) to determine the weights of the decision tendency in-dicators of drivers with different styles when making intersection passes respectively, combines the following model with the speed guidance, optimizes the following model to derive the optimal guidance acceleration, and derives the optimization curve through simulation. The study shows that the speed guidance model after considering the individual driver’s following behavior can improve the safety and meet the realistic driving scenario with certain reference value, while ensuring cer-tain vehicle passing efficiency.
