摘要
武汉城市快速路网呈"环+放射"的结构,为提高交通通信业务主干传输网络的可靠性和稳定性,提出了基于武汉市快速环路的智能交通业务通信主干环网的建设方案。该方案根据武汉市路网形态,围绕快速路网环线构建通信主干环网,结合基于SDH的多业务传输平台和自动交换光网络2种平台,共同为智能交通系统提供安全可靠的通信平台。
The expressway network of Wuhan City is a ＂ring ＋ radiation＂ structure.In order to improve the reliability and stability of traffic arterial communications network,a construction scheme of arterial traffic communication network based on Wuhan City express ring road is proposed.According to the form of Wuhan City Road Network,and by combining the two intelligent communication transportation systems platform of MSTP（multi-service transmission platform based on SDH） and ASON（intelligent optical network）,the scheme provides safe and reliable communication platform for intelligent transportation system.
