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 Vehiclesâ€"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.
TRB's National Cooperative Highway Research Program (NCHRP) Report 716: Travel Demand Forecasting: Parameters and Techniques provides guidelines on travel demand forecasting procedures and their application for helping to solve common transportation problems.
The report presents a range of approaches that are designed to allow users to determine the level of detail and sophistication in selecting modeling and analysis techniques based on their situations. The report addresses techniques, optional use of default parameters, and includes references to other more sophisticated techniqu
TRB's second Strategic Highway Research Program (SHRP 2) Report S2-C08-RR-1: Linking Community Visioning and Highway Capacity Planning explores community visioning efforts, identifies steps and activities that might be considered when engaging in visioning, and highlights the links between vision outcomes and transportation planning and project development processes.
The report also presents a modelâ€"the Vision Guideâ€"that is a blueprint for preparing, creating, and implementing a visioning process. As part of the project that produced Report S2-C08-RR-1, a companion web tool was
TRB's Transit Cooperative Research Program (TCRP) Report 153: Guidelines for Providing Access to Public Transportation Stations is intended to aid in the planning, developing, and improving of access to high capacity commuter rail, heavy rail, light rail, bus rapid transit, and ferry stations. The report includes guidelines for arranging and integrating various station design elements.
The print version of TCRP Report 153 is accompanied by a CD-ROM that includes a station access planning spreadsheet tool that allows trade-off analyses among the various access modes--automobile, tran
TRB's National Cooperative Freight Research Program (NCFRP) Report 16: Preserving and Protecting Freight Infrastructure and Routes provides guidance to decision makers involved in freight facility operations, freight transportation planning, and land use on how to avoid conflicting land uses or mitigate existing uses.
The report provides information about freight transportation and its importance to people's everyday lives; illustrates the types of conflicts between freight and other land uses and their consequences; and provides tools and resources designed to help preserve facilit
TRB's National Cooperative Freight Research Program (NCFRP) Report 14: Guidebook for Understanding Urban Goods Movement is designed to help facilitate decisions that accommodate and expedite urban goods movement while minimizing the environmental impact and community consequences of goods movement.
TRB's National Cooperative Highway Research Program (NCHRP) Report 707: Guidelines on the Use of Auxiliary Through Lanes at Signalized Intersections provides guidelines to help in the justification, design, and analysis of auxiliary through lanes (ATLs) at signalized intersections.
ATLs are lanes for through movements that begin upstream of a signalized intersection and end downstream of the intersection. ATLs are potentially a moderate-cost approach to increase intersection and overall corridor capacity.
A report that describes the research related to the development of
TRB's Transit Cooperative Research Program (TCRP) Synthesis 94: Innovative Rural Transit Services highlights transit and rural intercity bus service responses to changing rural community transportation needs. The report includes an emphasis on the innovative and/or entrepreneurial spirit, the innovator, and the conditions required for innovation.
TRB's National Cooperative Freight Research Program (NCFRP) Report 12: Framework and Tools for Estimating Benefits of Specific Freight Network Investments provides a framework and tools designed to help estimate the private and public benefits of potential freight infrastructure investments.
The evaluation framework is intended to assist public planning and decision-making processes regarding freight; to supplement benefit/cost assessment with distributional impact measures; and to advance public-private cooperation.
The framework is capable of handling projects that span
TRB's National Cooperative Highway Research Program (NCHRP) Report 708: A Guidebook for Sustainability Performance Measurement for Transportation Agencies describes the underlying principles of sustainability as it relates to transportation, possible goals that can be used to address those principles, and performance measures that can be used to address those goals.
Aspects of sustainability-related performance measures, including data sources and examples of use, are discussed. A reference compendium of performance measures has also been provided.
In addition to the guid
