FHWA Guidebook for Measuring Multimodal Network Connectivity

Joseph Broach, Portland State University



In 2018 the Federal Highway Administration issued a new guide, Measuring Multimodal Network Connectivity. TREC researchers contributed to the guidebook in partnership with Alta Planning + Design and ICF. The guide provides information on incorporating connectivity measures into state, metropolitan, and local transportation planning processes. It outlines five core components of pedestrian and bicycle network connectivity: network completeness, network density, route directness, access to destinations, and network quality. The guide provides a step-by-step framework for selecting and applying connectivity measures to help make decisions that are grounded in a comprehensive vision, supported by clearly defined goals and measurable objectives. It includes references and illustrations of current practices, including materials from five case studies conducted as part of the research process. The guide empowers all who are involved in transportation decision-making. By using multimodal measurements to inform the iterative, comprehensive process of planning and implementation, transportation agencies can more successfully create and improve active transportation options and systems.


A growing body of research points to the key role of high-quality, connected networks in making bicycling and walking safer, more convenient, and more prevalent.
Since connectivity has a strong influence on the likelihood of achieving these types of outcomes, planners can use ongoing connectivity assessments as leading indicators of the potential for the outcomes to ultimately occur. Connectivity measures can help fill gaps and address barriers in the transportation network, to increase safety for all users and improve access to jobs, schools, economic centers and other destinations.
