Project Summary
The integration of TAMS and CalVAD will enhance and expand the current data collection capability by providing better truck count estimates at conventional traffic monitoring sites. The new data could potentially help ARB to better define its scoping plan, understand freight movements, improve current methodology used in developing of the State Implementation Plan (SIP), improve EMFAC model, and provide data for calibration and validation of Metropolitan Planning Organization’s (MPO) and Statewide travel demand models. This research proposed aligns extremely well with ARB’s goals and mission by providing the best possible scientific and economic information. The results from this study will be used to improve inventory development such as ARB’s mobile source inventory, which will subsequently benefit air quality modeling which are the basis for critical planning efforts such as the State Implementation Plan (Federal Clean Air Act), Scoping Plan (AB-32), Sustainable Freight Action Plan (Executive Order B-32-15), and California Transportation Plan (SB-391). This will help to provide a better understanding of spatial and temporal medium and heavy duty trucks activity in California. Furthermore, it will help us track progress on performance of Sustainable Communities Strategies under SB375, and can be used by MPOs for transportation demand model calibration and validation.
