Public transportation systems include a variety of transit options such as buses, light rail, and subways. These systems are available to the general public, may require a fare, and run at scheduled times. . .Public transportation systems are often implemented at the local or regional level and can be supported by federal initiatives, such as the Fixing America’s Surface Transportation (FAST) Act. Los Angeles County is one example of a region that expanded its public transportation system using local, state, and federal funding.
