FHWA Publishes Report on Design Flexibility in Transportation Projects


The Federal Highway Administration (FHWA) recently released Achieving Multimodal Networks: Applying Design Flexibility and Reducing Conflicts, which highlights ways that transportation planners and designers can apply the design flexibility found in several current national design guides, including: the American Association of State Highway and Transportation Officials’ Guide for Geometric Design of Transit Facilities on Highways and Streets (AASHTO Green Book); the National Association of City Transportation Officials’ Urban Street Design Guide; the Transportation Research Board’s Highway Capacity Manual; and others.

The publication is intended to be a resource for transportation practitioners and designers seeking to build multimodal transportation networks while addressing common concerns and perceived barriers to design flexibility. The report also highlights case studies from across the country where practitioners have successfully applied design flexibility to achieve safe multimodal networks, while reducing multimodal conflicts and achieving connected networks so that walking and bicycling are safe, comfortable, and attractive options for people of all ages and abilities.

Landscape architects are leaders in designing multimodal transportation corridors that accommodate bicyclists and pedestrians, provide access to transit, and address stormwater management issues, as well as other benefits. Multimodal transportation networks provide access to jobs, education, healthcare, and other essential services in urban, suburban, and rural areas throughout the United States. Interconnected pedestrian and bicycle infrastructure makes walking and bicycling a viable transportation choice for everyone, and this contributes to the health, equity, and quality of life of our communities.
