TRB's National Cooperative Highway Research Program (NCHRP) and National Cooperative Freight Research Program (NCFRP) have jointly released NCHRP Report 649/NCFRP Report 3: Separation of Vehicles—CMV-Only Lanes. The report examines major issues and concepts that should be understood in developing new applications of commercial motor vehicle-only (CMV-only) lanes as a potential method for both easing congestion and reducing the number of traffic accidents on highways. Appendices A through D for NCHRP Report 649/NCFRP Report 3 should be available online as follows: Appendix A: NCHRP Project 03-73 Separation of vehicles—CMV-only lanes Task 7—Interim report; Appendix B: Performance evaluation; Appendix C: Benefits monetization factors and unit costs; Appendix D: Net present value calculations for benefit-cost analysis.
