逐步回归法在无检测器交叉口交通流量预测中的应用

Step-by-Step Regression Used in Traffic Flow Prediction of Non-Detector Road Intersections

在研究交叉口相关性的基础上 ,利用逐步回归法预测无检测器交叉口交通流量 ,并应用长春市路网的实际数据对结果进行了检验 ,取得了满意的效果。此研究成果有效地解决了无检测器交叉口交通流量的预测问题 ,它使得只有很少检测器交叉口的城市的交通流诱导成为可能 ,并为交叉口的宏观管理提供了理论依据。

Based on interrelationship between traffic flows of intersections,step by step regression is used to predict traffic flow of non detector intersections and results are verified by traffic flow data of Changchun City road network.The method can be widely used in urban traffic flow guidance in cities without enough intersections equipped with detectors,providing theoretical basis for macroscopic management of road intersections.
