A suite of recent policy and legislative initiatives are prioritizing a shift towards electrification of the personal-use vehicle fleet. This agenda is intimately tied to another complex issue: the sustainability of the primary transportation funding source (i.e., the gas tax—also known as the motor fuel tax). What makes this particularly hard is that gasoline consumption is only a proxy for “amount of travel.” With diversification in fuel sources and a concerted movement towards non-fossil fuel sources to power vehicles, any specific fuel source would be (at best) a weak or (at worst) grossly inequitable representation for amount of travel. Toward an Integrated Transportation Pricing Approach Using Vehicle-based Technologies will focus on some of the larger questions for an integrated pricing system based on miles driven that are measured directly using vehicle-based or in-vehicle technology communicating directly with infrastructure systems.

"As traditional sources of funding for the nation's surface transportation system fail to keep pace with demand, proposals for new sources have proliferated. New funding strategies, such as pricing the use of new and existing roads, and new institutional arrangements, such as public-private partnerships, have emerged over the past few years. As with all transportation policies, these strategies raise questions about equity. To address these concerns, the Transportation Research Board convened an expert committee to provide guidance to public officials about assessing the equity of evolving transportation finance mechanisms. The committee's findings are presented in this report. They are organized under the following chapter headings: (1) Equity and Transportation Finance; (2) How Transportation is Funded and Who Pays; (3) Equity Through Different Lenses; (4) Transportation Finance Equity: Evidence and Experience; (5) Equity and Decision Making: Experience with Road Pricing; and (6) Findings and Recommendations."--pub. desc.
