高速公路交通事故时有发生,并伴有二次事故,危害车内人员生命安全,而遇到地质灾害时,又容易造成交通拥堵. 为了提高我国高速公路智能化、信息化的管理水平,保证行车人员人身安全、提高道路畅通率,本文运用无线通信与组网技术,设计了由车载设备、路由节点和控制中心等组成的高速公路安全预警系统,并针对高速公路的特定环境,设计了基于TDMA的MAC协议与分簇式链式路由协议解决信息冲突、信息干扰以及路由路径选择等问题,借鉴无线传感网络的通信协议,实现无线链状网络组网,以确保对高速公路路况、安全隐患、交通事故定位以及其他交通信息进行实时监测和广播,提升高速公路智能化管理水平.

Traffic accidents occur frequently on expressways with secondary accidents following, endangering the safety of occupants of the related vehicles. Also geological disasters can often cause traffic congestion. In order to improve our expressways' intelligent information management, ensure the personnel safety of drivers and passengers, and improve the road flow rate, we designed an expressway safety early warning system consisting of vehicle-borne equipment, routing nodes and control centers, by using wireless communication and networking technology. In addition, in light of the specific environment of expressways, we designed a MAC protocol based on TDMA and a cluster based on a routing protocol to solve the problems of conflict of information chains, information interference and routing and path choice. We further set up a wireless chain network by means of the communication protocol for wireless sensor networks to ensure real-time monitoring and broadcasting of the information of the road conditions, safety hazards, traffic accident location positioning and other traffic information, and improve the intelligent management of expressways.
