基于物联网的智能交通流探测技术研究

Intelligent Transportation Flow Detection Technology Based on Internet of Things

为更好地分析和统计动态交通流以获得道路交通信息,将物联网技术与智能交通系统相结合,提出一种基于物联网的智能交通探测系统ITFDS(Intelligent Transportation Flow Detection System Based on Internet of Things)。ITFDS通过车载传感器节点获取原始交通参数并进行初次融合,汇聚点作为信息收集、分发与数据二次融合的中心节点,物联网中心控制机房则负责系统数据的统计与管理。仿真实验证明,ITFDS能有效、即时地获得道路交通流量值并将其发送至各车辆,作为车辆选择行进线路的依据。

In order to better analyze dynamic transportation flow so as to gain road traffic information,this paper combined the Internet of Things technology and the intelligent transportation system and proposed a new intelligent transportation detection system-ITFDS（Intelligent Transportation Flow Detection System Based on Internet of Things）.ITFDS obtains original traffic parameters and initial data fusion by vehicle sensor nodes.The sink is the central node for information gathering,distribution and secondary data fusion,and the center engine room is responsible for statistics and management.Simulation results show ITFDS can effectively and timely obtain the value of road transportation flow and send it to the vehicle,based on which travel routes can be selected.
