基于BP神经网络的微观交通安全预测方法
A Microcosmic Forecasting Model for Traffic Safety Based on BP Neural Network
摘要
Abstract
The principal component analysis and BP neural network were introduced into the prediction of traffic safety. Factors influencing traffic accidents were analyzed from microcosmic perspective. The road parameters were analyzed and the original data were obtained. The obtained data were then analyzed by principal component analysis, which later would be used as the input of BP neural network to predict the traffic safety. The result shows that the BP neural network based on principal component analysis has a higher accuracy than general BP neural network. Furthermore, the impact of road parameters on traffic accidents from the microcosmic perspective is achieved.关键词
