摘要: 用BP神经网络偏最小二乘法(BP-PLS)对路侧带行人服务水平(PLOS)进行评价;利用了神经网络能够很好 地描述评价结论与评价指标之间非线性关系的特性;偏最小二乘法弥补了BP模型在确定隐含层节点数和初始权 值方法上的不足。案例验证表明:BP-PLS模型具有很好的预测效果和较高的拟合精度,可以作为一种行人服务水 平评价方法。

Abstract: BP-PLS model was used to evaluate the pedestrian service level for sidewalks. The method was used with the advantage that the neural networks could correctly characterize the non-linear relationship between the evaluation results and evaluation indicators. The PLS was used to make up the defects of BP model relating the determination of node numbers for hidden layers and the weights initialization method. The case study shows that the BP-PLS model has a good capability for fitting and forecasting , which can be used to evaluate the pedestrian service level for sidewalks

Key words: traffic engineering, BP-PLS model, pedestrian service level for sidewalks
