【摘要】 雾天高速公路事故频发，车路协同技术发展为解决相关问题提供了新的思路。论文应用驾驶模拟技术构建基于车路协同的可变限速系统，研究雾天高速公路车载可变限速控制系统有效性及影响因素。设计雾天能见度水平（无雾、轻雾、浓雾）、信息给予方式（无提示、车载提示）6种实验场景。结果表明，车载提示能降低驾驶速度、加速度及进入雾区速度，Logistic回归分析表明随着限定速度的增加、雾区能见度降低及增加车载提示均能提升驾驶人对限定速度的服从度及驾驶安全性，并通过验证表明模型拟合效果及预测能力均较好。更多还原

【Abstract】 For solve frequent accidents problems in the foggy highway,a new ideas was provided.This paper applied driving simulation technology to build a variable speed limit system based on vehicle-road collaboration,and studied the effectiveness and influence factors of human machine interaction(HMI)in variable speed limit control system on foggy expressway.Six experimental scenarios were designed,including visibility level(no fog,light fog and heavy fog)and information delivery mode(no hint and HMI hint).The experimental results show that HMI warning can reduce driving speed,acceleration and speed into the fog zone.The logistic regression result show that the decreases of speed limit and visibility in fog zone and the use of the variable speed limit application can improved the driver’s compliance with the limited speed and driving safety.更多还原
