NCHRP Implementation Support Program. Implementing A Guidebook for Urban and Suburban Roadway Cross Section Reallocation

Design guidance exists for individual elements within a roadway, such as travel lanes, on-street parking, medians, and bicycle, pedestrian, and transit facilities. However, current design guidance does not reflect the complex and varied trade-offs transportation professionals consider for existing roadways in different contexts. NCHRP 15-78: Guidebook for Urban and Suburban Roadway Cross Section Reallocation developed a guidebook and decision-making framework for roadway designers, planners, and others for identifying, comparing, evaluating, and justifying context-based cross-sectional reallocations of existing urban and suburban roadway space for multimodal safety, access, and mobility. The project has four deliverables: (1) a guidebook, (2) a decision-making spreadsheet tool, (3) a final report, and (4) a presentation providing an overview of the project.
