The invention relates to the technical field of data processing, in particular to an urban traffic management system and method based on big data and cloud computing, and the method comprises the steps: collecting a traffic data sequence of each road section in urban traffic; obtaining reference range traffic data of the reference traffic data according to the traffic data sequence; obtaining a local traffic dispersion degree of the reference traffic data according to the reference range traffic data; obtaining a local abnormal weight of the reference traffic data according to the local traffic dispersion degree; acquiring a road section traffic ratio factor of the reference traffic data; obtaining a road section abnormal factor of the reference traffic data according to the road section traffic ratio factor; obtaining the final abnormal degree of the reference traffic data according to the road section abnormal factors and the local abnormal weights; and performing exception handling according to the final exception degree. According to the invention, the change trend of the traffic data is more obvious, the accuracy of the anomaly detection result is improved, and the management efficiency is improved.
本发明涉及数据处理技术领域,具体涉及一种基于大数据和云计算的城市交通管理系统及方法,包括:采集城市交通中每个路段的交通数据序列;根据交通数据序列得到参考交通数据的参考范围交通数据;根据参考范围交通数据得到参考交通数据的局部交通离散程度;根据局部交通离散程度得到参考交通数据的局部异常权值;获取参考交通数据的路段交通比因子;根据路段交通比因子得到参考交通数据的路段异常因子;根据路段异常因子以及局部异常权值得到参考交通数据最终异常程度;根据最终异常程度进行异常处理。本发明使交通数据的变化趋势更加明显,提高了异常检测结果的准确性,提高了管理效率。
