摘　　要：随着广东省地级市通高速公路建设完成,现在主要在进行通山区高速和跨省级高速建设,道路视频图像点越来越多,另随公路管理部门对公路安全性、服务水平提出的更高要求,视频图像的重要性也越来越明显。本文介绍了目前高速公路机电系统设计时视频图像传输常用的几种模式,对每种传输方式的基本原理、系统构成等进行了简要的叙述,并例举相应实例予以说明。With the superhighway construction of the province ground class city in Guangdong completion, primarily focused on carry on now a mountain area highway and across province class highway construction, the road video frequency more and more, another with highway management the section is to higher request that the highway safety, service level put forward and the importance of the video is also more and more obvious. This paper discussed the mode of video images transmission about highway, simple describe the rationale, system constitute of every transmission method by using some examples.
