NCHRP Report 649/NCFRP Report 3: Separation of Vehicles - CMV-Only Lanes presents an extensive compendium of information about CMV-only lanes and examines major issues and concepts that should be understood in developing new applications of CMV-only lane concepts as a potential method for both easing congestion and reducing the number of traffic accidents on highways. Appendices to this report, including an annotated literature review, performance evaluation criteria, benefits monetization factors and unit costs, and net present value calculations for benefit-cost analysis, are available on the TRB website. This report and the supplemental information can be used by public agencies that may be considering CMV-only lane concepts in corridor studies or other planning applications. The report provides data such agencies can use to support their own evaluations of CMV-only lane projects.

"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.
