Abstract:Road travel in light-duty vehicles, while of great economic value to private consumers and society, also generates a range of social costs. These include environmental damage from localized and global emissions, energy security concerns from petroleum use, external accident risk, and road congestion. These social costs are addressed only partially by the existing system of fuel taxation and road charges. Research on efficient pricing discusses how taxes might be set on motor fuel and road use to reflect social costs of motor vehicle use. The challenge is to understand how fuel and mileage taxation can alter market outcomes to better manage external costs while taking into account the appropriate level and balance of taxation. Because CAVs can change how people assess their time in vehicles, both in terms of quantity and quality, it is important to design robust policies that can allow the market development of CAVs to take advantage of their private benefits while establishing incentives for beneficial environmental and social outcomes. Our research has two thrusts. First, we make the first known contribution to proposing efficient tax levels for connected autonomous vehicle (CAV) road travel. It extends the existing research for conventional manually-driven vehicles and considers how tax policy may need to change for CAVs given their substantially different societal impacts and private incentives. Our second thrust addresses how consumers will use and adopt CAVs as they become available. We describe our methods and finding for these two thrusts separately but draw conclusions reflecting insights from both.
