Abstract:California, where transportation accounts for over half of ozone precursors and particulate matter emissions, as well as nearly 40 percent of greenhouse gas emissions, has adopted the ambitious goal of reducing petroleum use in transportation by 50 percent by 2030. One of the proposed strategies to achieve this goal is to increase the number of alternative fuel vehicles (AFVs) on the road. In California, incentives to foster the addition of AFVs include the removal of occupancy requirements to access high occupancy vehicle (HOV) lanes and parking privileges with charging facilities for Plug-in Hybrid Electric and Battery Electric vehicles. Although popular, the effectiveness of these incentives is not well known. In this context, this paper analyzes the 2012 California Household Travel Survey using a generalized structural equation model that accounts for residential self-selection, household demographic characteristics, and a measure of environmentalism. Our findings suggest that increased proximity to HOV lanes without occupancy requirement or to preferred parking/refueling facilities have a statistically significant but quite small impact (with odds ratios of 1.004 and 1.017 respectively). Pro-environmental beliefs reflected in voting behavior for environmental propositions are also statistically significant, but they have a potentially larger impact with an odds ratio of 4.733. This suggests the need to continue educating the public about the environmental impacts of fossil fuels while working with car manufacturers to make their products more attractive compared to conventional vehicles.
