A

California's complex and dynamic transportation system is in part both the cause and the result of the restless mobility of Californians, who tend to move and travel frequently. There is one of the greatest concentrations of motor vehicles in the world and the most extensive system of multilane freeways in California. However, freeway construction has declined since the 1970s because of public opposition.

Light rail transit systems were largely discontinued in California cities after World War Ⅱ. However, because of increasing traffic congestion (拥塞), many have been reintroduced or newly constructed. The Bay Area Rapid Transit (BART) system in and around San Francisco was constructed in the early 1970s and expanded in the following decades in response to growth in remote areas. A San Diego trolley (无轨电车) system, first built in the late 1970s as a link to the Mexican border, was extended in the late 1980s. Work on a subway system in Los Angeles began in the early 1980s. By 2003 a network of light rail lines ran through the city. Now there are rail links between downtown Los Angeles and many remote areas, including major tourist sites, airports and beaches. With an ever-growing population, more attention was paid to the development of mass transit systems, such as the light rail and the subway, in California in the early 21st century.

The transport of goods in California is carried out mainly by trucks, but the canals and waterways are also used to transport goods. Shipping across the Pacific basin is centered at the Long Beach, Los Angeles ports, whose cargo (货运量) is several times greater than that handled by the Oakland, San Francisco, and Richmond ports in northern California. Long Beach is one of the world's most important cargo ports.

Air transport in California has increased greatly. The air lines connecting San Francisco, Los Angeles, and San Diego create greater traffic than those linking Washington, D．C., New York City, and Boston on the East Coast. Air traffic congestion has become critical, but not so serious as that of the ground traffic near major California airports.
