Driving Change: Reducing Vehicle Miles Traveled in California

This report examines how California aims to reduce vehicle miles of travel (VMT) and thereby reduce the greenhouse gases which contribute to climate change. Land use, public transportation and pricing will all affect VMT and effective integration of these components could help achieve reduction targets. While residential density in California, even southern California, is higher than the national average, employment density, which has a greater impact on VMT, is low and declining. Transit-oriented development (TOD) can encourage greater ridership if an integrated approach including parking, pricing, and mix of businesses is used, but TOD by itself does not spur employment growth or the attendant ridership increase. Policy decisions need to support commercial development over residential development near stations. The appendices include a survey of planning agencies, the survey results, and tables summarizing the statistical analysis.
