The current system of funding highways is being rendered obsolete, as increased fuel efficiency decreases revenue from gas taxes and the system’s top-down structure discourages innovation and market-based solutions for congestion problems. A new study published by the Mercatus Center at George Mason University finds that replacing fuel taxes with a comprehensive system of vehicle mile charges—particularly if the change is accompanied by a greater role for private firms in owning or managing roads—would achieve a more efficient and equitable arrangement for funding surface transportation infrastructure and could eliminate most congestion without requiring a massive expansion of the highway network. The study outlines the advantages of such a system compared to the status quo, and presents options for avoiding potential problems, such as privacy issues, in its design and implementation.
