城市交叉口车路网联信息对青年驾驶人驾驶行为的影响分析

基于驾驶模拟器设计了城市道路信号和无信号交叉口场景下的模拟驾驶实验,研究网联信息的存在和内容对青年驾驶人工作负荷和操纵行为的影响.实验共包括被试26人,均为22～30岁的青年驾驶人.结果表明:对无信号交叉口(区分次干路直行车辆和主路对向左转车辆)或信号交叉口红灯时间即将结束时,网联信息可以显著降低青年驾驶人的工作负荷,...

Effects of Information from Connected Vehicles and Infrastructure on Driving Behavior of Young Drivers at Urban Intersections

This paper aims to investigate the effects ofthe existence and content of information from connected vehicles and infrastructure (CVI) ondriving workload and behavior of young drivers at signalized and non-signalized intersections. Driving simulationsfor such intersectionsin urban areas are developed, in which 26 young drivers aged between 22 and 30 are involved. The results show that: such information can significantly reduce the workload of young driversand the increase in heart rate reduced by 1.95 beats/min for signalized intersections and 2.96 beats/min or 3.29 beats/min for non-signalized intersections, respectively. In addition, such information can significantly reduce the response time for braking actions of young drivers with 2.35 s at signalized intersections and 2.71 s or 2.09 s at non-signalized intersections respectively. It is also found that it can improve the stability of vehicles in reducing the standard deviations of vehicle speed by 31.33% for signalized intersections and 47.40% or 60.23% for non-signalized intersections, respectively. In addition, when thered phase of the vehicle moving direction at signalized intersections is about to end, the command information from CVI can significantly reduce the response time of young drivers by 3.47s, and the standard deviation of vehicle speed by 39.10%, compared to the effectiveness of regular instruction information.
