A performance-based approach for highway geometric design is proposed in a report produced under the National Cooperative Highway Research Program. The report, A Performance-Based Highway Geometric Design Process (NCHRP Report 839), includes a brief history of highway design in the U.S., including recent advances, and recommends that multimodal solutions be addressed in the geometric design process. The report includes principles for an effective highway design process, such as including quantitative measures of transportation performance in design solutions. It also provides potential approaches to updating the AASHTO geometric design guidance (the Green Book). For more information, link to the report. (4-14-17)
The use of context sensitive solutions (CSS) and environmental justice (EJ) to enhance livability will be addressed in an April 12 webinar sponsored by the Federal Highway Administration. The webinar will include discussion of strategies such as stakeholder engagement, identification of adverse impacts and implementation of CSS to improve livability in disadvantaged communities. The webinar also will include discussion of how CSS and EJ principles can be incorporated into the transportation decisionmaking process. For more information, link to the registration page.

A primer to assist state and local agencies with developing performance-based practical design (PBPD) programs is now available from the Federal Highway Administration. According to the guide, PBPD is the next step in the evolution of project development and design decision-making. The approach encompasses initiatives such as practical design, context sensitive solutions, and value engineering. It provides a renewed focus on project scoping to address purpose and need and reduce the cost of projects. The guide offers steps for starting a PBPD program, including learning, marketing, rollout and execution. It also provides lessons learned from existing programs and additional resources. For more information, link to the guide. (3-16-17)
The Federal Highway Administration has released five case studies that illustrate the range of contexts for performance based practical design (PBPD) in transportation systems management, and operations strategies and tools. The case studies show how PBPD can be implemented through analysis of high-occupancy toll lanes, urban free reconstruction, alternative intersections, regional performance-based planning and analysis of active traffic management. For more information, link to case studies regarding toll lanes, urban freeway reconstruction, alternative intersections, regional performance-based planning and active traffic management. (1-11-17)
The Federal Highway Administration has issued a report concerning the application of performance-based practical design (PBPD) with transportation systems management and operations (TSMO) for complete streets projects. PBPD comprises analysis tools for evaluating performance impacts and design decisions to successfully implement TSMO, which include multimodal and intermodal systems and services. The report includes case studies that address implementation of road diets in both low and moderately higher traffic volume areas. The case studies focus on the installation of bike lanes, congestion relief and the addition of green space to improve the livability of streets for residents. The report says that combining PBPD and TSMO strategies increases project efficiency by ruling out design options early on and successfully developing safety and mobility objectives.
