Developed a methodology and computer model component for integration into Southern California Association of Governments' (SCAG) regional model to be able to better forecast heavy-duty truck activity and its associated vehicle miles traveled within the SCAG region. A heavy-duty truck was defined as a truck with a gross vehicle weight of 8,500 pounds or greater.
488750.00
SCAG covers Imperial, Los Angeles, Ventura, San Bernardino, Orange and Riverside Counties.
No actual emissions were reduced by this study. The objective in developing a new heavy-duty truck forecast model was to provide a means for more accurately estimating truck emissions. Truck activity is a significant contributor to regional emissions, NOx and particulate matter especially. It is important to have accurate estimates of how regional economic changes and regional transportation plans affect truck activity and the resulting emissions.
