| 摘 要： | 针对交叉口进口道交通状态的模糊性和不确定性,在综合考虑影响进口道交通状态因子的基础上,选取到达率、排队长度、信号周期、饱和度和车道数为预测交叉口进口道交通状态的影响因子。采用判别分析法中的Fisher判别法,利用调查得到的样本数据建立了交叉口进口道交通状态预测模型,并用调查得到的验证样本进行验证,结果表明利用Fisher判别法能够有效的进行交叉口进口道交通状态的预测。

| Abstract: | Aimed at the vagueness and uncertainty of traffic state at intersection entrance,we chose the influence factors including arrival rate,queue length,signal cycle,saturation,and number of lane for predicting traffic state at intersection entrance based on comprehensive consideration of influence factors of traffic state at entrance.We established the traffic state prediction model for intersection entrance through surveyed sample data based on Fisher discriminant analysis,which is verified by the related samp... |
