关于LED信息显示技术在高速公路上的应用

Application of LED Information Displaying Technology in Expressways

随着我国高速公路交通的蓬勃发展,高速公路上的智能交通管理在保障车辆交通安全、提高交通管理效率等方面发挥着越来越重要的作用。信息发布的载体LED可变情报板与限速标志在高速公路信息发布系统中作为信息显示终端为车辆引导提供车况、路况等交通信息,高速公路信息发布系统可显示各种图像和文字,通告各种交通情况和气象信息,发布交通指令,保证交通行车安全。所显示的图像和文字既可以事先编制、存储在可变情报板控制器内,也可在可变情报板计算机上随时进行编制、再发布,它将为保障高速公路的行车安全提供重要的软件环境。并作为高速公路上的智能交通管理的一部分,为高速公路交通的高效、智能化的管理发挥了不可替代的作用。

BWith the rapid development of expressways in China, the intelligent traffic management on expressways is playing a more and more important role to safeguard the vehicle safety and raise the efficiency of traffic administration. As the media of information releasing, LED Variable Message Sign and Speed Limited Sign play important roles in intelligent traffic management system, The expressway information releasing system can display various kinds of text and graphics and also can inform the traffic and weather condition and the traffic instruction, as to ensure the safety of the drivers. The text and graphics can not only be compiled in advance and stored in the controller, but also can be edited randomly and re-published on the computer. This will provide an important software environment to ensure the traffic safety on expressways, And as a part of intelligent traffic management on expressways, the LED variable message sign plays an un-substitutable role in highly efficient and intelligent management of expressways.
