The invention discloses a traffic state detection method and detection device. The method comprises the following steps: obtaining N speed intervals through division based on the free flow speed of afirst road section, and dividing the traffic state of the first road section into N levels; determining a vehicle proportion corresponding to each speed interval in the N speed intervals, and determining a first traffic state level corresponding to the maximum vehicle proportion in the vehicle proportions corresponding to the speed intervals; and determining the traffic state corresponding to thefirst traffic state level as the traffic state of the first road section in the current time period. In this way, the influence of each vehicle speed on the detection of the traffic state of the firstroad section by the detection device is fully considered by the detection device, and the dependence on historical vehicle driving data is small, so that the accuracy of the detection result of the detection device on the traffic state of the first road section can be improved.
本发明公开了一种交通状态检测方法及检测装置,该方法包括:基于第一道路断面的自由流车速,划分N个速度区间,并将第一道路断面的交通状态的等级划分为N个等级;确定N个速度区间中的每个速度区间对应的车辆占比,并确定每个速度区间对应的车辆占比中的最大车辆占比对应的第一交通状态等级;将第一交通状态等级对应的交通状态确定为第一道路断面在当前时间段内的交通状态。通过这种方式,检测装置充分考虑每个车速对检测装置检测第一道路断面的交通状态的影响,且对于历史车辆行驶数据依赖性较小,从而可以提高检测装置对第一道路断面的交通状态的检测结果的准确性。
