New Approach to Setting Speed Limits to Improve Safety on Mountain Roads
Posted: Aug 30, 2022
University of Wyoming researchers developed a new system for setting speed limits on roadways that are characterized by steep downgrades and curves. They used high-fidelity dynamic simulation modeling to assess lateral and roll stability of different vehicle types on various road surface conditions. The study offered a holistic design framework for safe vehicle speeds with respect to lateral and roll stability, including vehicle configurations (weight/truck load height) and wind parameters (speed and direction). Their work provides guidelines regarding the design of road sections with steep grades and curves and for the implementation of safety countermeasures on existing curved roads.
