The invention relates to a dynamic road traffic information acquisition method and system and a storage medium. The method comprises the steps of S1, equidistantly arranging a plurality of road side units for realizing relay communication between an operation center and vehicle-mounted units along the side of a road, and controlling each road side unit to be networked with the vehicle-mounted uniton each vehicle in an adjacent range so as to form a local area network; S2, controlling the operation center to periodically requesting vehicle condition data from each vehicle-mounted unit in eachlocal area network through the road side units, wherein the vehicle condition data comprises the vehicle speed of the vehicle-mounted unit; and S3, for each local area network, according to the vehicle speed in the local area network, controlling the operation center to adjust the period of requesting the vehicle condition data from each vehicle-mounted unit in the local area network in real time.The invention aims to dynamically acquire road traffic information, so that the total amount of vehicle condition data uploaded by vehicles driving on the road can be adaptively adjusted according tothe road congestion condition.
本发明涉及一种动态道路交通信息采集方法及系统、存储介质,其中方法包括:步骤S1.沿道路旁侧等间距设置用于实现运营中心与车载单元中继通信的多个路侧单元,控制每个路侧单元与邻近范围内的各车辆上的车载单元进行组网,以形成局域网络;步骤S2.控制运营中心经路侧单元周期性向每个局域网络中的各个车载单元索取其车况数据,其中车况数据包含车载单元的车速;步骤S3.对于每个局域网络,根据该局域网络内的车速,控制所述运营中心实时调整向该局域网络内各个车载单元索取所述车况数据的周期长短。本发明旨在动态采集道路交通信息,使路上行车所上传的车况数据总量能随道路拥堵情况自适应调整。
