摘要:
为了探究高速公路混有智能网联车队交通流特性,构建了混合交通流中不同类型车辆随机分布特性的数学解析表达;考虑期望车头间距随速度动态变化的交通流特性,建立了混合交通流中不同类型车辆的跟驰模型.基于此,推导了混有智能网联车队的交通流基本图模型,并对模型参数渗透率p和最大车队规模的敏感性进行了分析.仿真结果表明,随着p值的增加,道路交通流通行能力随之提升,当p<0.3时,渗透率增加对于混合交通流通行能力提升效果并不显著,而当p>0.5时,混合交通流通行能力随着渗透率增加提升效果显著;另外,随着智能网联车辆的渗透率p增加,车队规模的限制对交通流通行能力的影响越来越明显,当p<0.5时,车队规模宜保持在4~6之间,而p接近1时,车队规模增大对通行能力的提升效果更加显著.
Abstract:
To explore the characteristics of mixed traffic flow with platoons of intelligent connected vehicles, a mathematical analytical expression that can reflect the random distribution characteristics of different types of vehicles in mixed traffic flow is proposed. Considering the dynamic characteristics of desired headway changing with speed, the car-following model of different types of vehicles was established. Based on this, the fundamental diagram of the mixed traffic flow with intelligent connected vehicle platoons was derived. Moreover, the sensitivity analyses of the market penetration rate of connected vehicles and the maximum platoon size were made. The simulation results show that the traffic capacity is gradually improved with the increase of the market penetration rate p. When p<0.3, the improvement of capacity is not significant as the market share increases. When p>0.5, the improvement of capacity is significant as the market share increases. In addition, with the increasing popularity of intelligent connected vehicles, the impact of the platoon size on traffic capacity becomes more and more significant. Meanwhile, the platoon size should be maintained between 4 and 6 when p<0.5, and the larger platoon size is recommended when p is nearly equal to 1.
