Modeling in the development of virtual campus include buildings and landscape. For buildings, it is possible to use visualization software, such as AutoCAD and 3DS MAX, with VRML to create, also create entirely in VRML. The modeling of landscape is mainly completed in VRML. This paper discusses in detail VRML-based modeling detail and modeling techniques(More)
Traffic flow data are un-periodical, nonlinear and stochastic, the practicability and accuracy are affected due to its drawbacks of falling into local optimization and low convergence rate. Thus, RBF neural network optimized by particle swarm optimization algorithm (PSO-RBFNN) is proposed to predict traffic flow in the paper. Being easy to realize, simple(More)
