通过分析山区低等级公路不同弯道半径的安全车速的特点以及路标的安装位置,采用TruckSim仿真分析,建立数学模型;设计了基于为即将进入弯道入口的司机提供弯道出口的路况和前方有弯道的信息以及自主定位的智能交通路标;最后通过实验分析确定系统各模块的安装位置;结果验证了系统具有较强的稳定性,检测准确率极高。 Based on the analysis of the characteristics of safety speed and the installation position of road signs for different corners of mountainous low-grade road, TruckSim simulation is used to establish the mathematical model. The road conditions based on the exit of the curve for the driver who is about to enter the curve and the front Cornering information and self-positioning intelligent traffic signposts. Finally, the installation position of each module of the system is determined through experimental analysis. The results verify that the system has strong stability and high detection accuracy.
