A Neural Network Model for Trip Generation Forecasting

Due to the drawbacks of aggregate trip generation forecasting model, this paper brings forward a new model using back-propagation neural network, which has the advantages of non-linear relation mapping. Based on the analysis of the structure and the algorithm of a neural network, the influencing factors, network structure and discrete data were fully researched. Furthermore, the model was verified and applied using the data from a big city＇ s resident trip survey. The result shows that the forecasting model has high precision, which proves its good maneuverability as well as profound theoretical advantages. At last, the future research direction is discussed.
