Abstract:This report summarizes the findings from the project After SB375: Using Statewide Activity- Based Modeling to Assess the Impact of Sustainable Community Strategies on Regional and Interregional Travel Behavior, funded by the University of California Transportation Center (UCTC). The project investigates the effects of some of the proposed land use and transportation policies that are currently being developed by Metropolitan Planning Organizations (MPOs) in California, as an effect of recent environmental regulations, on regional and interregional trips, personal and total vehicle miles traveled (VMT), modal split, and VMT per capita.
