The invention discloses an intelligent network connection traffic state monitoring method and system based on multi-source data fusion, and particularly relates to the technical field of intelligent traffic, and the method comprises the steps: obtaining the speed data of M data sources in an nth topological road section in a T time period, and carrying out the preprocessing of the speed data, so as to obtain a data quality coefficient of the nth topological road section; the data quality coefficient of the nth topological road section is analyzed, whether M data sources meet requirements or not is judged, if not, a data optimization instruction is generated, and if yes, a state analysis instruction is generated; according to the method, the data quality coefficient is calculated by analyzing the speed data of the M data sources, so that the accuracy and the reliability of the input data can be ensured. And when the data source does not meet the requirement, a data optimization instruction is generated, so that the influence of low-quality data on the system is avoided. Through the real-time detection and optimization mechanism of the data quality, the interference of data noise or missing is reduced, and the accuracy of the fusion model is improved.

    本发明公开了多源数据融合的智能网联交通状态监测方法及系统,具体涉及智慧交通技术领域,包括:在T时间段内,获取第n条拓扑路段中M条数据源的速度数据,对速度数据进行预处理,以获得第n条拓扑路段的数据质量系数;对第n条拓扑路段的数据质量系数进行分析,判断M条数据源是否符合要求,若不符合,则生成数据优化指令,若符合,则生成状态分析指令;本发明通过分析M条数据源的速度数据,计算数据质量系数,有助于确保输入数据的准确性和可靠性。当数据源不符合要求时,生成数据优化指令,避免低质量数据对系统的影响。通过数据质量的实时检测与优化机制,减少数据噪声或缺失的干扰,提高融合模型的准确性。
