Forecasting the vessel traffic flow in the bridge areas is focused on this study. Based on Hybrid Radial Basis Function Neural Network, another novel predictive statistic modeling technique called Enhanced Hybrid Radial Basis Function Neural Network (EHRBF-NN) is proposed in the paper. EHRBF-NN is a flexible forecasting technique that integrates regression trees, particle swarm optimization, with radial basis function neural networks. In this technique, the regression tree is used to determine the centers and radius of the radial basis functions. The Particle Swarm Optimization (PSO) is used to avoid the over fitting and determine the weights of the neural network. Computer simulations have been implemented to validate the EHRBF-NN. Compared forecasting results with actual data, the algorithm of HRBF-NN is more effective than ordinary RBF-NN, RBF-NN with least square method and HRBF-NN, while it uses less computing resources and shorter computing time.
