Jurisdiction[edit]

The agency is a public transportation and planning agency that lies under the jurisdiction of the State of California. Although it falls under State regulations, it can also partake in regional and municipal levels of rule during a transportation development project.[25] For example, it can play a role in policies regarding a state's housing policies, since the living situation of one affects the methods of transportation its residents will take.[26]


This transit agency can measure successful projects through key pointers such as low income ridership increase and an increase of favorable environmental and health factors for its public community.[27] Increased low income ridership is a significant factor because that focus group tends to makes up the majority of public transit ridership.[27] Favorable environmental and health factors are also relevant factors because they indicate a positive relationship within the space developed and its residents.[25]

Future[edit]

NextGen Bus Plan[edit]

Metro is currently implementing its "NextGen Bus Plan," a major restructuring of the agency's routes. The plan eliminates most of the Metro Rapid routes and low-performing Metro Local lines to invest in the remaining routes. Metro says the plan will double the number of frequent bus lines (defined as a bus every 10 minutes or better) and expand midday, evening, and weekend service while ensuring that 99% of current riders continue to have a less than 14-mile walk to their bus stop.
