The parking meter was invented in 1935 by Carl C. Magee in Oklahoma City, introducing a pioneering solution to urban traffic congestion. Known as the "Park-O-Meter," this device transformed city parking management by promoting efficient usage of parking spaces, reducing street congestion, and encouraging turnover in commercial areas. The success of the parking meter led to its widespread adoption in numerous cities and played a pivotal role in the evolution of modern urban parking systems.
