摘要
射频识别(RFID)技术作为交通领域较新的数据采集技术,利用RFID技术采集交通参数是车路协同新领域探索的技术支撑。本文基于实现实时道路交通状态判别这一目的,采用RFID系统采集城市道路车辆数据,通过构建交通参数计算方法,将车辆数据转化为交通流量、流速、密度等道路交通参数,参照速度阀值判断道路实时交通状态,通过结合路段交通量的转移分布和历史平均行程时间分析,建立了适用于RFID技术的交通状态模型,预测未来短时间内路段以及区域交通状态的变化情况。
As a new date acquisition technology in traffic field,using RFID acquisition the traffic information parameters is new exploration in the field of technical support. In order to analyze the urban road traffic congestion,this paper makes a judgment on the urban road traffic condition based on RFID technology,collects the urban road vehicle data through the RFID system,detects the traffic state of the road section. Build a traffic parameter calculation method to obtain traffic flow,velocity,density and other traffic parameter information based on RFID technology acquired data characteristic in detection and data structure in the database. Transfer and historical average travel time,so as to forecast the traffic volume of the road section at a certain time.
