• Abstract:
  In this research, techniques for estimating and forecasting the three critical mobile source emission related travel indicators were developed. The three indicators are vehicle age distribution, mileage accumulation rates by vehicle type, and VMT related variables. As for estimating vehicle age distribution, two types of models were developed. Model Type I (MT I) models the number of vehicles for the particular vehicle type in particular age and then transfers the results to project the future age distribution. Model Type II (MT II) models the future age distribution directly. Both model types contain a family of linear models, nonlinear models and time series models. Based on a certain kind of criteria, the best model can be chosen from the two model families. Examples for the eight counties in Houston-Galveston Area Council (HGAC) area and in El Paso area are used for examination.
