交通标志智能化现状研究

Research on the status of intelligent traffic signs

交通标志作为基础交通设施,提供有效的交通信息引导驾驶人驾驶车辆安全到达目的地。智能网联车辆技术快速发展,交通标志向智能车辆提供信息利用无线传输、信息指令等方式辅助智能汽车在路上安全运行,交通标志传递信息的方式由逆反射光线传递变为无线通信传递。文章总结了基于逆反射交通标志应用现状和智能化交通标志的功能设计、结构组成和应用的趋势,研究可知智能化交通标志由多种传感器组成,可以实时采集、计算路面信息并提供给智能汽车,驾驶人能够通过多个途径获取交通标志的信息,辅助驾驶人安全驾驶,交通标志智能化是未来发展的方向。

Traffic signs,as basic traffic facilities,provide effective traffic information to guide drivers to drive their vehicles safely to their destinations.With the rapid development of intelligent networked vehicle technology,traffic signs provide information to intelligent vehicles using wireless transmission,information instructions and other ways to assist intelligent vehicles to operate safely on the road.The way traffic signs transmit information changes from retro-reflective light transmission to wireless communication transmission.This paper summarizes the current situation of the application of retroreflective traffic signs and the trend of functional design,structural composition and application of intelligent traffic signs.The study shows that intelligent traffic signs consist of multiple sensors that can collect and calculate road information in real time and provide it to intelligent vehicles.Drivers are able to obtain the information of traffic signs through multiple ways to assist drivers to drive safely.Therefore,intelligent traffic signs are the next direction of development.
