The invention relates to the technical field of data processing, in particular to a smart city traffic management system and method based on big data, and the method comprises the steps: dividing an original time series data sequence into a plurality of time periods, calculating the uniqueness of each piece of data in the time periods, equally dividing the time periods into a plurality of small time periods, and calculating the uniqueness of each piece of data according to the weights corresponding to the small time periods. Determining the complexity of data values in the time period, determining the complexity of data change in the time period in combination with the periodic regularity of data change in the time period, and determining the importance of the time period in combination with the repeated characteristics corresponding to the time period and the correction coefficient of the original time sequence data sequence; therefore, a data sampling time interval corresponding to the time period is determined, data sampling of the time period is completed, data sampling of the original time sequence data sequence is completed, and sampling data is compressed and stored. According to the invention, through the adaptive data sampling time interval, the precision and accuracy of the data are ensured while the sampling data is less.
本发明涉及数据处理技术领域,具体涉及基于大数据的智慧城市交通管理系统及方法,包括:将原始时序数据序列划分为若干个时间段,计算时间段内每个数据的唯一性,再将时间段等分为若干个小时间段,根据小时间段对应的权重,确定时间段内数据值大小的复杂性,结合时间段内数据变化的周期规律性,确定时间段内数据变化的复杂性,再结合时间段对应的重复特征以及原始时序数据序列的校正系数,确定时间段的重要性,由此确定时间段对应的数据采样时间间隔,完成时间段的数据采样,从而完成原始时序数据序列的数据采样,对采样数据进行压缩存储。本发明通过自适应数据采样时间间隔,令采样数据较少的同时,保障数据的精度和准确性。
