    Abstract
  • Based on nonlinear forecast theory of track irregularity, a forecast model was developed by multiple factor regression analysis with traffic data and inspection data of track inspection car. Future track irregularity development was forecasted using this model. The values of forecast and inspection were compared, and the error between them was analyzed. It was pointed that the figures of forecast and inspection are similar. The result indicates that it is feasible using the model to forecast longitudinal irregularity.
