Designing for Safe Mobility

A Holistic, User-Centric Approach to Roadway Design

KYTC’s Designing for Safe Mobility website houses critical knowledge roadway designers need to plan and design facilities that deliver on the promise of providing safe and efficient mobility for all users. Along with short primers on topics that inform contemporary design best practices, users can search content found in Human Factors Guidelines for Road Systems (NCRHP Report 600). The site will be refreshed often so it remains a trusted, up-do-date resource for designing safe, context-adapted facilities.
