【Abstract】 A new theory model is brought forward and the model based on BP neural network is used in highway freight volume combination forecasting.This model flexibly applied the capability that the neural network can fit any non-linear function by self-adaptation and self-learning,avoiding the shortage effectively that traditional combination forecasting method forces the relationship among the data on some sort of function in the application.With the help of MATLAB,some simple program is compiled.It decreases the difficulty of calculation.The example has proved that this method has higher prediction precision.更多还原
