Adoption of the LOS framework by individual state DOTs has generally been consistent with the Highway Capacity Manual, although usage and application may vary across […]
The Safe System approach is a holistic approach that provides a framework for making the U.S. national transportation system safer. It is based on building and reinforcing multiple layers of protection to prevent crashes from happening and minimize the harm caused when crashes occur. This safety approach differs from conventional ones because it focuses on […]
Transportation planning agencies and officials face a rapidly evolving technical, policy, legislative, and procedural environment. Agency professionals often seek the guidance of peers and experts to help them effectively address these challenges.
