TRANSPORTATION CONTROL EFFECTIVENESS IN OZONE NON-ATTAINMENT AREAS: FINAL REPORT

The main objective of this project is to develop a prototype of an integrated and coordinated regional transportation planning and emissions modeling procedure. The procedure will be flexible in structure to accommodate continual advances in travel demand methods and improvements in the MOBILE model. The need for an integrated and coordinated Transportation Control Measure (TCM) air quality analysis procedure has been emphasized by a review of the state-of-the-art modeling practice used by 41 metropolitan planning organizations (MPOs) and nine states in the country (Chatterjee et al. 1997). The report provides recommendations for improvements in traffic input data for emissions modeling. These recommendations are based on a detailed sensitivity analysis that shows the high sensitivity of the emissions factor model to many input traffic data.
