摘 要: 行程时间预测是交通流诱导系统研究的一项重要内容.在分析各种行程时间预测方法的基础上,本文建立了基于BP神经网络的行程时间实时预测模型,编制了行程时间预测软件系统. Travel time estimation is an important aspect for the traffic flow guidance system. In this paper, based on analysing several methods to estimate the travel time, we establish a real time travel time estimation model by using backpropagation neural network. The software system of the model is developed. The model is tested with detected data collected in Changchun city.
