摘　　要：文中通过构建四种中央分隔措施(双黄线加交通隔离栏、双黄线加弹性交通柱、双黄线加突起路标、单黄线)应用场景并开展驾驶模拟试验,分析了不同措施对车辆运行状态的影响.结果表明:在双黄线加弹性交通柱和交通隔离栏的设置下,车速显著降低,横向偏移明显增大且离散性也增大;弯道路段车速偏低、横向偏移偏高;右转时车速较高、横向偏移较低,且驾驶人对车辆的控制能力也比左转要差;中央分隔措施、线形和转弯方向这三个因素对驾驶行为不存在交互影响作用;总的来看,建议在限速不超过40 km/h的单洞双向的低等级公路隧道中推广应用双黄线加弹性交通柱的措施,以提高隧道的安全性.By constructing four application scenarios of central separation measures(double yellow lines with traffic barriers,double yellow lines with elastic traffic posts,double yellow lines with protruding road signs and single yellow lines)and carrying out driving simulation tests,the influence of different measures on vehicle running state was analyzed.The results show that under the setting of double yellow lines with elastic traffic posts and traffic barriers,the vehicle speed is significantly reduced,the lateral deviation is significantly increased and the dispersion is also increased.The speed of curve sec-tion is low and the lateral deviation is high.When turning right,the vehicle speed is higher,the later-al deviation is lower,and the driver's ability to control the vehicle is worse than that of turning left.There is no interactive influence on driving behavior among three factors:central separation meas-ures,alignment and turning direction.Generally speaking,it is suggested that the measures of double yellow lines and elastic traffic columns should be popularized and applied in single-hole two-way low-grade highway tunnels with speed limit not exceeding 40 km/h to improve the safety of tunnels.
