基于BP神经网络的短时交通流预测

Short-time Traffic Flow Prediction Based on BP Neural Network

对比分析短时交通流预测模型,对BP神经网络预测算法的原理进行分析说明,用BP神经网络建立短时交通流预测模型,利用华南快速路的实测交通流数据来验证模型的可行性。

By comparing with analysis of short - time traffic flow prediction model, this paper analyzes and expatiates the principle for BP neutral network prediction algorithm, establishes short - time prediction model by means of BP neural network, and verifies the feasibili .ty of model by use of measured traffic flow data from South China expressway.
