Speed Humps Adopted in Multiple US Cities to Reduce Traffic Speeds

Speed humps are increasingly recognized as a cost-effective and popular traffic calming measure that significantly reduces vehicular speeds and improves road safety. Unlike other traffic interventions that often face opposition, speed humps tend to be welcomed by nearby residents and cost around $5,000 to install, making them an accessible solution for many communities. Research highlights their effectiveness, such as a 43% reduction in speeding in Arlington, Virginia, and notable speed decreases in South Korea. However, some cities like Cambridge, Massachusetts, have yet to adopt speed humps, opting instead for more extensive traffic calming programs, which can delay implementation. In Lansing, Michigan, the recent installation of speed humps on Clemens Avenue followed a rigorous approval process, reflecting the thorough measures cities take to ensure appropriate use and community support. These examples illustrate the growing role of speed humps in urban traffic management and their potential to enhance safety with relatively low cost and community acceptance.
