摘　　要：在现有的城市交通环境中,信号交叉口的周期阻隔性造成了车辆急加速、急减速和怠速等驾驶行为,使车辆产生额外的尾气排放和燃油消耗,加剧了交通堵塞和环境污染等问题。有效的车速引导模型可以提高信号交叉口处的车辆通行能力,故以三角函数优化的车速引导模型为基础,考虑到驾驶员在实际驾驶时无法完全跟踪速度引导曲线,设计了一种闭环反馈速度更新算法,以动态补偿人车响应特性造成的跟踪偏差。仿真结果表明:基于动态闭环反馈的车速引导模型不仅可以有效提高信号交叉口处车辆的通行效率,还能够增强车速引导系统对驾驶员的适应性。In the existing urban traffic environment,the periodic obstruction of signal intersections causes vehicle driving behavior such as acceleration,deceleration and idling,which causes additional exhaust emissions and fuel consumption,aggravates traffic congestion and environmental pollution.An effective speed guidance model can improve the traffic capacity of vehicles at signalized intersections.Based on the triangular function optimized speed guidance model,a closed-loop feedback speed algorithm is designed to dynamically compensate for the tracking errors caused by the response characteristics of human-vehicle.The simulation results show that the speed guidance model based on dynamic closed-loop feedback can not only effectively improve the traffic efficiency of vehicles at signalized intersections,but also enhance the adaptability of the speed guidance system.
