Research on Traffic State Prediction Modal of Intersection Entrance Base on Discriminant Analysis

In accordance with vagueness and uncertainty of traffic state in intersection entrance, the paper chooses prediction influence indexes of traffic state in intersection entrance, including arriving rate, rank length, signal circle, saturation degree and lane amount, which is based on the comprehensive consideration of influence indexes of traffic state in entrance. Traffic state prediction modal of intersection entrance is obtained through survey sample data base on fisher discriminant analysis, meanwhile the modal is testified and verified by sample data, results show modal take advantage of predicting traffic state of intersection entrance by fisher discriminant method.
