汽车驾驶室内道路交通信号仿真研究

Research on Simulation of Road Traffic Signal in Automobile Cab

道路交叉口信号灯是保障道路网络节点交通秩序有条不紊的保障。为了解决实际交通中某条道路上前方有大型车辆遮挡或大雾等不良天气原因,导致后方车辆驾驶员无法辨识前方信号灯的问题,文章提出了一种在汽车驾驶室内自动显示前方道路交通信号系统的方法,并给出了本方法的技术路线。通过3Dmax和SolidWorks仿真软件建立了车内交通信号系统模型,实现了车内交通信号的传输与显示。结果表明,该方法可以使前方交叉口的交通信号在驾驶室内实时显示,解决了视线遮挡而无法观测前信号灯的实际问题,从而减少了驾驶员的心理负荷,提高了道路交叉口的交通安全性。

The traffic signal lights at road intersections are the guarantee to ensure the orderly traffic of road network nodes.In order to solve the problem that the driver of rear vehicle can not recognize the front signal lights because of the sight occlusion such as large vehicle occlusion or bad weather in actual traffic,this paper presented a method of displaying the front road traffic signal system automatically in an automobile cab,and gave the technology route of the method.Through the simulation software of 3D Max and SolidWorks,the traffic signal system model of automobile cab was established,and the transmission and display of the traffic signal in automobile cab were realized.The results show that the method can display the traffic signals in the cab at the front intersection in real time and solve the actual problem that the front traffic signal lights can not be observed because of the sight occlusion,thus reducing the driver's psychological load and improving the traffic safety of the road intersection.
