Project Summary
This proposal describes a project that will review ARB's current method of adjusting emissions from on-road motor vehicles to reflect activity on weekend days. For the purpose of this project, weekend days are expanded to include Friday, Saturday, Sunday and Monday. The review will examine the current approach in detail, including an analysis of the input data and the intended use cases. The review process proposed also includes a review of the literature to identify current practices to this problem. Following this review, the study team will propose improvements to the existing method that will: address any shortcomings found; add best practices from the literature; and integrate the current approach into typical ARB work processes.
