Quick Summary

Road transportation refers to the movement of people and goods via roads, encompassing everything from local streets to major highways. The automobile revolutionized this sector, offering unprecedented personal freedom and convenience compared to fixed-route mass transit. This led to rapid growth in car ownership, particularly after World War II, and the development of extensive highway systems, often funded by fuel taxes.1

The widespread use of automobiles has brought challenges, including traffic congestion, air pollution, and accidents. While mass transit, often utilizing buses, remains important, its effectiveness is challenged by urban sprawl and the dispersed nature of modern living. Road planning and traffic control systems, using signs, signals, and markings, are crucial for managing this complex network and ensuring safety. Transportation, especially automobile-related expenses, constitutes a significant portion of national economies.2134
