The invention relates to the technical field of traffic control, in particular to a highway traffic flow detection and evaluation method, system and device and a medium. According to the method, firstly, a video detector, a radar detector and a coil detector are used for cooperatively collecting parameters such as vehicle type distribution, vehicle speed distribution and vehicle head distance, and then a vehicle flow heterogeneous index including a cart influence coefficient, a vehicle speed difference coefficient and a car-following safety degree is calculated based on the data; further analyzing a traffic flow operation state to obtain a traffic capacity attenuation characteristic, and finally evaluating the traffic efficiency of different road sections. And the operation quality of the mixed traffic flow can be reflected more comprehensively and accurately.

    本申请涉及交通管控的技术领域,尤其涉及一种高速公路交通流检测和评价方法、系统、设备及介质。本申请首先利用视频检测器、雷达检测器和线圈检测器协同采集车型分布、车速分布和车头间距等参数,然后基于这些数据计算包含大车影响系数、车速差异系数和跟驰安全度的车流异构指数,进而分析交通流运行状态得到通行能力衰减特征,最终实现对不同路段通行效率的评价;能够更加全面和准确地反映混合交通流的运行品质。
