There is nationwide interest in supporting sustainable and active transportation modes such as bicycling and walking due to the many benefits associated with them, including reduced congestion, lower emissions and improved health. Although the number of bicyclists is increasing, safety remains a top concern. In urban areas, a common crash type involving bicycles at intersections is the “right hook” where a right-turning vehicle collides with a through bicyclist. While geometric treatments and...

Jennifer Dill , Kelly Clifton
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 dest...
