BP神经网络对逼近实数值提供了一种顽健有效的学习方法,适合对路口交通流量进行预测。针对BP神经网络存在易陷入局部最小值和收敛速度慢的问题,提出了一种集成BP预测模型。该模型集成多个具有不同初始权值和训练集的BP模型,并以加权平均值的方法作为结合方法。其中的每个BP模型是以一种改进的MapReduce方法实现的。将该模型运用到交通路口车辆分流流量大小的预测实例中,并依次与单机实现的单个BP模型和MapReduce实现的单个BP模型进行比较。结果表明,集成BP模型在路口车辆分流流量大小的预测中有较高的准确率和实时性。
BP neural network provides a robust and effective learning method for approximating real values. It is fit for intersection traffic flow prediction. In order to resolve its slow convergence speed and easily falling into local minimum problem,an ensemble prediction model was proposed. This model integrated multiple BP neural networks which had different initial weights and training set and used weighted average as combination method. It had used an improved MapReduce method to implement every BP neural network of the ensemble prediction model. This ensemble prediction model took traffic shunt flow prediction at intersection as an example. At last,it was compared with simple single implementation BP model and MapReduce implementation BP model respectively. Finally,results prove that ensemble prediction model has a higher accuracy rate and real-time performance in traffic shunt flow prediction at intersection.
