Roadside Design for the Safety and Comfort of Nonmotorized and Micromobility Users

In 2022, there were 7,522 pedestrian deaths and 1,105 bicyclist deaths on U.S. roadways, the highest number of pedestrian deaths since 1981 and the highest number of bicyclist deaths since 1975, according to Insurance Institute for Highway Safety (IIHS). In response to the rise in pedestrian and bicyclist fatalities, the Federal Highway Administration (FHWA) and agencies across the United States have adopted the Safe System approach. As part of this initiative, many agencies have implemented Complete Streets policies and legislation. As implementation continues, best practices for selecting, designing, implementing, and maintaining roadside features and facilities to accommodate nonmotorized and micromobility users are not broadly recognized under a variety of context. Practitioners are seeking guidance on the development of roadway features and facilities to better accommodate nonmotorized and micromobility users across a variety of context classifications, functional classifications, traffic speeds, and traffic volumes. Furthermore, roadside design guides have historically focused on cross-section elements between intersections, but many crashes involving nonmotorized and micromobility users occur at intersections and driveways. There is a need to develop a performance-based decision-making framework to select roadside features and facilities in various roadway contexts and provide insight on the effectiveness of new roadside features, facilities, and intersection treatments to address safety concerns of nonmotorized or micromobility users. The objective of this research is to develop a performance-based guide to support state departments of transportation (DOTs) and other transportation agencies to select roadside features and facilities in various roadway contexts for the safety and comfort of nonmotorized and micromobility users. The guide will focus on quantitative and qualitative evaluations of the safety and comfort of nonmotorized and micromobility road users with considerations for implementation and maintenance of the roadside features and facilities.
