Estimating Policy Effects on Reduced Vehicle Travel in Hawaii

This report describes methods for estimating future vehicle miles traveled (VMT) in Hawaii under two conditions: 1) business as usual, and 2) a policy scenario, developed by the authors as a framework for the State of Hawaii to meet its ambitious climate goal of 100 percent clean energy by 2045. The overarching strategy for reducing transportation emissions from ground transportation in Hawaii includes a major shift toward zero emissions vehicles—namely, electric vehicles powered by clean energy. The slow pace of this transition paired with increasing travel demand, however, will likely pose a major challenge to meeting the state’s climate goals. This report focuses on policies for managing and reducing travel demand—land use regulations, increased transportation options, and transportation pricing mechanisms—and ties those policies to their likely impact on VMT, based on current trends and knowledge from related research. This ambitious policy scenario reduces vehicle travel demand by an estimated 7.3 percent by 2045, even after accounting for population growth.
