The invention discloses a traffic data distribution validity discrimination method and device. Obtaining single-day traffic flow data collected by the traffic flow detection equipment with the data distribution validity to be identified; carrying out preprocessing on the single-day traffic flow data; performing parameter distribution feature extraction on the preprocessed single-day traffic flow data to obtain distribution features of the single-day traffic flow data; based on a trained neural network classifier, according to the distribution characteristics of the single-day traffic flow data, obtaining the probability that the single-day traffic flow data belongs to each category; and determining whether the distribution characteristics of the single-day traffic flow data are valid or not according to the probability that the single-day traffic flow data belong to each category, and determining the category to which the single-day traffic flow data which is judged to be valid belongs.

    本申请公开了一种交通数据分布有效性判别方法及装置。获取待识别数据分布有效性的交通流检测设备采集的单日交通流数据;对所述单日交通流数据进行预处理;对预处理后的单日交通流数据进行参数分布特征提取,得到所述单日交通流数据的分布特征;基于训练后的神经网络分类器,根据所述单日交通流数据的分布特征,得到所述单日交通流数据属于各类别的概率;根据所述单日交通流数据属于各类别的概率确定所述单日交通流数据的分布特征是否有效,以及对于被判定为有效的单日交通流数据确定所属的类别。
