The invention discloses an expressway traffic flow data quality detection method, and relates to the technical field of expressway traffic. The expressway traffic flow data quality detection method comprises the following steps: photographing vehicles passing through an expressway; the shot picture is processed; detecting the speed of the vehicle; carrying out data processing and statistics on the obtained traffic information; under the condition that the line is normal, traffic data are transmitted to a highway information processing center in a wired mode; when the line is damaged, the traffic data is transmitted to an expressway information processing center in a wireless transmission mode. Through the arrangement of the infrared camera, the high-definition camera, the speed measuring radar, the information processor, the liquid crystal display screen, the information transmission line, the wireless transmission communicator and the memory, automatic acquisition and automatic processing of traffic information are realized, and the traffic information is sent to a highway information processing center, so that a lot of manual operations are reduced, and the traffic information processing efficiency is improved. And the workload of workers is reduced.

    本发明公开了高速公路交通流数据质量检测方法,涉及高速公路交通技术领域。高速公路交通流数据质量检测方法,包括以下步骤:对从高速公路上经过的车辆进行拍照;对拍得的照片进行处理;对该车辆进行速度检测;将得到的交通信息进行数据处理与统计;在线路正常的情况下,将交通数据以有线的方式传输到高速公路信息处理中心;线路损坏时,以无线传输的方式将交通数据传输到高速公路信息处理中心。本发明通过红外摄像头、高清摄像头、测速雷达、信息处理器、液晶显示屏、信息传输线路、无线传输通讯器和存储器的设置,实现交通信息的自动采集与自动处理,并将之发送到高速公路信息处理中心,减少了许多的人工操作,减轻了人工的工作量。
