  • 摘要:AbstractThis paper presents a forecasting method called k nearest neighbor based local linear wavelet neural network (kNN-LLWNN) for the on-line, short-term prediction of five-minute traffic volumes at westbound of Interstate 64 in Hampton Road in Virginia. The method is based on combining k nearest neighbor (k-NN), with local linear wavelet neural network (LLWNN). The idea is to apply k-NN method to form the training dataset for LLWNN instead of taking the whole historical dataset for training. The proposed model is compared with k-NN, LLWNN and support vector regression (SVR) separately from prediction accuracy and running time two aspects. Experiments are conducted to decide the most appropriate parameters for the four models for the verification dataset. For the test dataset, the study's findings appear to confirm the hypothesis that, kNN-LLWNN performs comparable with LLWNN and SVR, and its running time is much lower than LLWNN and SVR because of the introduction of k-NN.
