Completed Studies

The Orange County Transportation Authority (OCTA) studied a 23-mile stretch of State Route 91 (SR-91), located in the County of Orange from the Los Angeles to Riverside county lines.

The Orange County Transportation Authority (OCTA) is studied mobility hubs as a potential strategy for bringing together various mobility services, amenities, and technologies all in one place to connect travelers more conveniently to their destinations.

Over the next 25 years, the population in south Orange County is anticipated to grow by 16 percent (about 170,000 residents), and employment is expected to grow by 18 percent (about 130,000 jobs). This study addressed south Orange County’s mobility needs through the year 2045.

OCTA completed a study to analyze and develop options to improve Beach Boulevard mobility options from Pacific Coast Highway in Huntington Beach to Whittier Boulevard in La Habra; and to evaluate possible improvements necessary to support local land use visions.

OCTA is conducting a study about how climate change effects the Orange County rail corridor. The study will identify opportunities and challenges to improve service, operation, and infrastructure to better withstand severe weather conditions.

OCTA has developed a comprehensive and county-wide bus, rail, and paratransit plan that will serve as a vision for Orange County’s transit future.

The Orange County Transportation Authority (OCTA) is developing a hazard mitigation plan designed to support current OCTA emergency and crisis management plans and to strengthen the organization's preparedness to natural hazards. Examples of natural hazards include flooding, earthquakes, and wildfires.

OCTA is studying existing and future transit connections between Orange and Los Angeles Counties. The Connect OC-LA Transit Study will identify both short and long-term improvements to the transit infrastructure and services between the two counties.

OCTA is studying the development of two Freeway Bus Rapid Transit (BRT) routes on Interstate 5 (I-5) and State Route 55 (SR-55). The Freeway Bus Rapid Transit Concept Study will identify improvements to infrastructure and transportation solutions for potential Bus Rapid Transit (BRT) routes and identify stops along each corridor.

OCTA has initiated a study to analyze and develop options to improve Bristol Street mobility options from West 17th Street to Sunflower Avenue; and to evaluate possible transit connections between this corridor and the John Wayne Airport.

Pacific Coast Highway (PC) is a major corridor that links Orange County’s six coastal cities—Seal Beach, Huntington Beach, Newport Beach, Laguna Beach, Dana Point, and San Clemente. The goal of the study was to identify, evaluate, and recommend long-term multimodal improvement recommendations both on a corridor-wide and subarea-wide basis.

OCTA conducted a study to analyze and develop options to improve Harbor Boulevard’s transit systems from Westminster Boulevard in Santa Ana to Chapman Avenue in Fullerton.

State Route 91 (SR-91) is a transportation corridor with strategic value and local, regional and national significance. Every day, the SR-91 connects hundreds of thousands of commuters living in Riverside County with employment centers in Orange County, and vice-versa.

The ability to efficiently move people, goods and services is critical for the sustained economic growth and quality of life in Orange County. Due to rapid growth in both residential development and employment, south Orange County residents are finding it increasingly difficult to avoid traffic congestion. Interstate 5 (I-5) is the main transportation corridor in the South County area. It is an eight-lane highway with traffic volumes as high as 350,000 vehicle trips per day.

As a follow up to the Orange and Los Angeles Intercounty Transportation Study that was completed in July 2008, the Southern Association of Governments (SCAG), in coordination with OCTA and Los Angeles County Metropolitan Transportation Authority (METRO), is conducting a study to assess the feasibility of transit service along the Pacific Electric Right of Way connecting Orange and Los Angeles Counties.

OCTA owns over 40 miles of operating railroad right-of-way in Orange County along the Los Angeles – San Diego – San Luis Obispo (LOSSAN) rail corridor. In 2005, OCTA completed the Orange/Olive Grade Crossing Study, which presented a ranking of 51 at-grade rail-highway crossings (grade crossings) along the LOSSAN rail corridor, including both the Orange and Olive subdivisions.

The City of Costa Mesa (City) identified congestion on State Route 55 (SR-55)/Newport Boulevard as a significant quality of life issue for adjacent residential and business communities. As a result, the City requested that the Orange County Transportation Authority (OCTA) together with its partner agency, the City Newport Beach, study alternative improvements to the extension of the Costa Mesa Freeway.
