中文摘要：

针对传统交通信息采集的弊端,基于IEEE 802.11p标准,利用ARM3000平台提出了一种TinyOS环境下交通信息采集自组网系统方案,给出了系统的整体框架结构,详细介绍了TinyOS环境下交通信息采集自组网系统的MAC层、路由层和应用层的设计方法,给出了自组网系统中传感节点、汇聚节点、管理节点的软件工作流程。以通用城市交叉口为例,从检测数据的可靠性、时延、传输距离等3个方面对系统进行了测试,结果表明,该方案稳定可靠,对进一步开发相关的实用系统具有参考意义。

英文摘要：

Aiming at the drawbacks of the traditional traffic information collection, an Ad Hoc Network scheme of traffic information collection based on IEEE 802.11p was proposed by using ARM3000 platform. The structure of the system was introduced. The design method of MAC layer, routing layer and application layer of Ad Hoc Network on tinyos were explained in detail, while the software workflow of sensor node, sink node and management node was given. Taking general city intersection as an example, the system was tested from three aspects of reliability, data delay and transmission distance. It shows that the design scheme proposed is stable and rehable, which has reference significance to develop practical system.
