The invention relates to a regional traffic flow prediction method and system. The method comprises the following steps: acquiring historical traffic flow data of a vehicle in a target area, and dividing the historical traffic flow data of the target area according to time periods to obtain historical traffic flow data of multiple periods; selecting one of the period historical traffic data and inputting the period historical traffic data into a first traffic flow prediction model to obtain long-term and short-term traffic flow prediction data, and respectively inputting each period historical traffic data into a second traffic flow prediction model to obtain a plurality of least square traffic flow prediction data, and superposing and reconstructing the plurality of least square traffic flow prediction data to obtain vector machine prediction data, and inputting the long-term and short-term traffic flow prediction data and the vector machine prediction data into a weighted average prediction model to obtain regional traffic flow prediction data. According to the invention, the prediction precision of the regional traffic flow is improved.

    本发明涉及一种区域交通流量预测方法及系统。所述方法,包括:获取车辆在目标区域的历史交通流量数据,将所述目标区域的历史交通流量数据按照时间周期进行划分,得到多个周期历史交通流量数据;选取其中一个所述周期历史交通数据输入第一交通流量预测模型,得到长短期交通流量预测数据,将各所述周期历史交通数据分别输入第二交通流量预测模型,得到多个最小二乘交通流量预测数据,并将多个所述最小二乘交通流量预测数据进行叠加重构得到向量机预测数据,将所述长短期交通流量预测数据和所述向量机预测数据输入加权平均值预测模型得到区域交通流量预测数据。本发明提高了区域交通流量的预测精度。
