This law requires the commission to manage and coordinate all public transportation services within the county to ensure they run smoothly and efficiently. Additionally, it has the responsibility to settle any disagreements between different public transit operators.

This law says that when a commission starts working, it must focus on supporting applications for federal funding if either an application has already been submitted or significant progress has been made to apply for funds to build a transit guideway project. This support is important to ensure that the progress of securing federal money is not slowed down.

This law requires any plans for public mass transit systems, including exclusive transit guideways and certain highway projects, to be submitted to the commission for approval. These plans must align with the regional transportation plan. However, the commission does not have the authority to approve safety and maintenance projects for the state highway system—those are handled by the Department of Transportation. For major highway rebuilds or rehabilitations, the department and commission must work together. Here, 'plan' refers to a project description, not detailed technical plans.

If a transit system is proposed to operate across multiple counties, the plan must be approved by a special transportation planning agency that covers those counties. This agency has 60 working days to make a decision once the plan is submitted.

This law section explains that a commission is responsible for appointing operators for transit guideway systems in California.

In Los Angeles County, the Southern California Rapid Transit District is designated as the operator, except where a different designation is specified by another law.

In Orange County, the Orange County Transit District has been designated as the operator for the transit guideway system.

The City of Los Angeles can build and run a transportation system at or between its airports. Once it's working, this system must be coordinated with local traffic and transit services by the relevant county transportation commission. Los Angeles also needs the commission's approval to apply for federal or state highway or transit funds for these projects, except for funds granted before 1978.

This law requires that if a commuter or urban rail transit system is planned to cross two or more counties, those counties must create a joint powers entity. This entity will handle tasks like planning, designing, choosing technology, figuring out costs, and managing the construction and operation of the rail system.

The joint powers entity will also decide who operates the rail system. If state money is involved in running the system, the plan must be offered to the Legislature at least four months before starting service.

This section of the law mandates that any plans for building guideway and rapid transit systems must be coordinated with both the Department of Transportation and the main regional transportation planning agency.

This law lets the commission make a deal with the Department of Transportation to help plan and build public transit systems, like subways or buses, where the department is capable. However, the commission keeps the final say on any important decisions about these systems. Any work the department does must follow applicable laws and regulations relevant to both parties.

This law states that if the Los Angeles County Transportation Commission is given the go-ahead to build a transit guideway system, it must work closely with the Southern California Rapid Transit District. The district is responsible for running the system once it's built.

This law requires the transportation commissions in Riverside and San Bernardino Counties to set up local transportation zones by February 1, 1978. Los Angeles and Orange Counties have the option to do the same, working alongside various agencies and the community.

The creation of these zones should involve local government and public entities, and consider geographic shapes, economies of scale in transit, and travel patterns. Guidelines for these zones must cover their governance, potential for multicounty zones, and how transportation services are offered, either directly, through cooperation, or by contracting with other transit providers.

The Orange County Transportation Commission can set up local transportation zones, but only when the Orange County Transit District cannot deliver sufficient and responsive services efficiently and cost-effectively in those areas.

This law allows the Los Angeles County Transportation Commission to create local transportation zones, but only in areas where eight voting members (or their alternates) agree that existing transit services, provided by either the Southern California Rapid Transit District or a municipal operator, are not meeting community needs cost-effectively.

This law requires that all public transportation bodies work together to coordinate things like schedules, routes, and transfers. It ensures that these groups don't compete with each other or duplicate services. Instead, they should collaborate to offer the best and most cost-effective service possible to the public.

This law states that the Los Angeles County Transportation Commission cannot decrease the size of service areas or the level and scope of services provided by current municipal transit operators unless they first talk with these operators and get approval from the cities where they operate.
