Assessing Highway Tolling and Pricing Options and Impacts, Volume 1: Decision-Making Framework, NCHRP Report 722
NCHRP Report 722, Volume 1 presents a decision-making framework that includes descriptions, evaluation of methods, and analytical tools to assess pricing options and forecast their impacts on travel behavior and congestion. The research identifies improved methods and analytical tools to fill gaps in existing capabilities to understand how tolling and pricing can be used to fund new roadway capacity and manage congestion. The findings of the research are provided in two volumes: the first addresses decision-making frameworks, while the second focuses on improvements to travel-demand forecasting methods and analytical tools. Volume 1 presents the most common steps that together form an overall decision-making framework for tolling and pricing projects. Each step is associated with a set of critical assessments, where accumulated experience and wisdom is summarized in the form of practical recommendations.
Report S2-C04-RW-1 - Improving Our Understanding of How Highway Congestion and Pricing Affect Travel Demand
The objective of this project was to develop mathematical descriptions of the full range of highway user behavioral responses to congestion, travel time reliability, and pricing. These descriptions were achieved by mining existing data sets. The report estimates a series of nine utility equations, progressively adding variables of interest. This research explores the effect on demand and route choice of demographic characteristics, car occupancy, value of travel time, value of travel time reliability, situational variability, and an observed toll aversion bias. The primary audience for this research is professionals who develop travel demand and traffic forecasts. Policy makers may also have an interest in the behavioral findings that could have policy implications.

Upon symposium discussions, presentations, and review of resource papers, an evaluation of the state of practice, future direction and opportunities are provided, and research and information needs are identified.
Curbing Gridlock: Peak Period Fees to Relieve Traffic Congestion
This 1994 Transportation Research Board (TRB) Special Report 242 focuses on congestion reduction and examines the public perception of congestion pricing. Although road users pay fuel taxes to support the costs of building and maintaining roads, most users view roads as free. In this report, congestion issues are outlined, and economic theory and analytical modeling are used to illustrate impacts of variable pricing. Preliminary results of federal policy, such as the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA), are also described and viewed as a potential means of gaining public acceptance for wider application of pricing experiments at the local level. The full report can be purchased on the TRB website.

Completed in 2008 for the National Cooperative Highway Research Program (NCHRP), this report synthesizes and analyzes public opinion on tolling and road pricing across the United States and internationally. It compiles existing data from completed public opinion research and presents an interpretive framework for understanding situational context in outcomes from various public opinion polls. The study also provides a systematic review of public opinion with respect to tolls and road pricing. This resource is intended for public and elected officials making decisions about infrastructure policy and projects and officials in the process of considering, planning, implementing, and operating tolled facilities.
NCHRP Synthesis 364: Estimating Toll Road Demand and Revenue
This 2006 synthesis prepared for the National Cooperative Highway Research Program (NCHRP), reports on the state of the practice for forecasting demand and revenues for toll roads in the United States. The synthesis focuses on models used to forecast travel demand and considers application of these models to project revenues as a function of demand estimates. Goals of this study included: developing a profile of the current state of the practice in toll road demand forecasting; identifying technical modeling issues that affect the accuracy, effectiveness, and reliability of the forecasts; and making recommendations for research to improve the state of practice. This resource is intended for state departments of transportation (DOT), metropolitan planning organizations, tolling authorities and operators, potential investors, bond rating agencies, and consultants who prepare models and forecasts on behalf of DOTs and other toll facility owners.
NCHRP Web-Only Document 161: System Trials to Demonstrate Mileage-Based Road Use Charges
Transitioning from fuel taxes to VMT fees would be a complex undertaking, with many technical, institutional, and political uncertainties to be resolved. To prepare for such a transition, it could be helpful to conduct an extensive set of system trials. The goal in this study was to explore options for scoping and organizing such trials. The research team solicited the thoughts and perspectives of representative stakeholders and subject matter experts through an extensive set of guided interviews followed by a one-day workshop. Based on participant responses and supporting research, the report outlines several approaches for funding, organizing, structuring, managing, and conducting a set of VMT-fee system trials. The trials could be complemented by parallel efforts in the areas of planning and policy guidance, analytic studies, technical research and development, and public education and outreach.
NCHRP Web-Only Document 143: Implementable Strategies for Shifting to Direct Usage-Based Charges for Transportation Funding
There is interest in determining whether it might be possible to implement a system of VMT fees rapidly, commencing by 2015. The goal in this study was to identify a range of options that might support the near-term implementation of a national system of VMT fees and evaluate their relative strengths and weaknesses. Based on the research, three options appear to offer the greatest promise: metering mileage based on fuel-consumption, metering mileage based on a device combining cellular service and a connection to the onboard diagnostics port, and metering mileage based on a device featuring a GPS receiver. While each of these approaches has its own set of advantages and disadvantages, there are also significant uncertainties that make it difficult to determine the optimal configuration at this juncture. A set of activities - encompassing planning, analysis, technical research and development, expanded real-world trials, and education and outreach - could resolve the uncertainties and set the stage for implementing VMT fees beginning in 2015.
TRB Special Report 285: The Fuel Tax and Alternatives for Transportation Funding
TRB formed the Committee for the Study of the Long-Term Viability of Fuel Taxes for Transportation Finance to respond to concerns of funding arrangement, like motor fuel taxes, which may become a less reliable revenue source for transportation programs in the future. This 2006 study was sponsored by the state transportation departments through NCHRP, FHWA, and TRB. With the goals of assessing recent trends impacting the future of traditional transportation finance, identifying finance alternatives and the criteria by which they should be evaluated, suggested ways for how barriers to acceptance of new approaches could be overcome are also provided. The Committee's recommendations propose immediate changes to strengthen the existing highway and transit finance system and actions to prepare for more fundamental reform in the long term.
TRB Special Report 299: Discerning the Pathway to Implementation of a National Mileage-Based Charging System
The Executive Committee of the Transportation Research Board commissioned this paper to: 1) develop and propose concepts for research and demonstration programs to test the technical and political feasibility of road use metering and mileage charging; 2) develop and expand upon the recommendations of TRB Special Report 285: The Fuel Tax and Alternatives for Transportation Funding that examined a structure to support the conduct of trials or pilot projects by individual states with federal leadership and funding aid; and 3) develop cost estimates for the demonstrations and related research to design and implement the trials. Part One of the report facilitates understanding among policymakers and researchers of the decision making necessary for constructing an acceptable mileage charging system as well as reviews work to date. Part Two proposes additional research to fill in knowledge gaps and obtain the data and information necessary for policymakers and researchers to reach a knowledge level for the opportunity at hand sufficient to enable legislative action.

NCHRP 19-08: Costs of Alternative Revenue-Generation Systems (Report 689)
The current system for generating the revenues that support federal-aid and state highways is based largely on federal and state fuel taxes. The objective of this research was to develop a methodology that can be used to analyze and compare the administrative, collection, and compliance (enforcement) costs of systems for highway revenue generation and to apply that the methodology to a selected set of usage-based revenue systems: cordon pricing, tolling, VMT fees, motor fuel taxes, and parking. Costs among revenue systems were normalized (for the three with comprehensive data available - motor fuels taxes, tolling, and VMT fees) and compared along several metrics: $ per lane mile, $ per centerline mile, $ per 1,000 VMT, $ per vehicle, $ per transaction, and % of total revenue. One primary conclusion is that the existing fuel tax system is the most costs effective among those examined and has the lowest operating costs for all unit measurements. The report also examines technologies required to implement alternative revenue generation systems as well as the results of a sensitivity analysis.
