Transportation design has incorporated performance-based approaches for many years, primarily in relation to materials such as pavement or steel. Results from projects sponsored by the National Cooperative Highway Research Program (NCHRP) are bringing these approaches to highway and street geometric design. This article looks at the history of roadway design criteria, other adopters of performance-based approaches, meeting the needs of diverse users, and the need for flexible contextual design. It also outlines NCHRP Report 785, "Performance-Based Analysis of Geometric Design of Highways and Streets." The report presents a framework to support a range of initiatives, including context-sensitive design and solutions, performance-based practical design, flexibility in design, complete streets, and multimodal design.
