Research for the AASHTO Standing Committee on Planning. Task 85. Congestion Pricing and Investment Requirements

The Federal Highway Administration (FHWA) has introduced the concept of congestion pricing to the HERS-based Condition and Performance Report in the 2006 issue. This research-based approach dramatically diminishes investment requirements and generates vast amounts of revenue - creating a swing on the order of $50 billion per year. The report indicates that average prices to produce this effect were on the order of 20 cents per mile ranging much higher where necessary. The report leaves many questions unanswered which the proposed research described here is intended to address.   It will be essential for the American Association of State Highway and Transportation Officials (AASHTO) to be prepared to fully understand this new addition to the needs process and to recognize and be able to evaluate its implications. Two broad tasks are entailed. Task Area 1 - Understanding the Analytical tools. The consultant will document the assumptions used by FHWA to quantify the relationship between cost and travel demand. The consultant will also identify and summarize the research used by Federal Highway Administration (FHWA) to develop the assumptions. This information will then be compared to similar assumptions used for specific pricing projects and regional plans across the US. Task Area 2 - The Effects of Congestion Pricing on Travel Decisions and Costs Congestion pricing reduces congestion by forcing some travelers to shift their trip times, to shift to other modes, to change their route to non-priced routes, to postpone trips or to cancel trips. What are the economic and social consequences of such developments?  How do they vary by type of traveler, purpose of the trip, or by regional context? In addition there are many questions bout the financial implications of congestion pricing, including costs to the public in direct expenditures, revenues raised and investment needs deferred. The HERS' estimates are at such a gross level that it is not possible to use them to explore the effect of the pricing schemes on individual traveler's decisions or the financial impact the individual traveler, state and local transportation agencies, and the private sector. However, these issues are critical to decision makers and the public and, of course, need to be part of the consideration when comparing alternatives. Facility specific modeling and experiences in areas that have implemented congestion pricing might be effective in establishing what can the models tell us; what consequences cannot be modeled, and what should the public and decision makers know about congestion pricing alternatives. This task would a reconnaissance of current methods, approaches, and experience that could lend insight and understanding for reauthorization planning.
