Prediction of Mobile Source Emissions and Fuel Consumption Using the TEXAS Model

Tsai-Yun Liao and Randy B. Machemehl, University of Texas at Austin, June 1995, 49 pp.

EMPRO is the emissions processor of the TEXAS traffic simulation model and was developed for predicting mobile source emissions and fuel consumption at intersections. Due to changes in federal emissions and fuel consumption standards since the 1981 EMPRO development, updating of vehicle characteristics was badly needed. This report describes the method for developing the EMPRO processor, the procedure for revising vehicle emissions and fuel consumption models, and the model prediction capability.
