speedreduction
Speed reduction, sometimes written as speedreduction, refers to processes, devices, or policies designed to decrease the velocity of a moving object or system. It can occur naturally through drag and friction, or be induced intentionally by mechanical systems, control strategies, or regulatory measures. The term is used in multiple fields, including mechanical engineering, automotive technology, physics, and traffic safety.
In mechanical systems, speed reduction is achieved with gear trains, belt and pulley drives, worm gears, or
In vehicles, speed reduction includes braking processes, which convert kinetic energy into heat, and regenerative braking
In traffic engineering and public policy, speed reduction refers to measures intended to lower vehicle speeds
