ETSI EN 302 636-3规定了智能交通系统中的通信网络体系结构 （ITSC）。网络架构主要关注但不限于车辆通信。该体系结构支持 广泛应用于道路安全、交通效率以及信息娱乐和商业。本文件定义了提供数据交换的网络和数据传输协议的框架 在它的车站里。一个特别的方面是提供临时和多跳的地理网络协议 利用地理位置通过短程无线技术进行通信。

ETSI EN 302 636-3 specifies a network architecture of communications in Intelligent Transportation Systems (ITSC). The network architecture is focused on, but not limited to, vehicular communication. The architecture enables a wide range of ITS applications for road safety, traffic efficiency as well as for infotainment and business.The present document defines the framework for network and data transport protocols that provide data exchange among ITS stations. A particular aspect is the GeoNetworking protocol that provides ad hoc and multi-hop communication over short-range wireless technologies utilizing geographical positions.
