The Los Angeles County Metropolitan Transportation Authority, commonly known as LA Metro, has launched an innovative initiative titled the One Car Challenge, offering up to $600 to 2,000 local households to leave at least one of their vehicles parked for five weeks. As the most populous county in the United States with approximately 9.6 million residents, Los Angeles faces severe car dependency and chronic traffic congestion. To combat this, the transit agency is incentivizing residents to transition toward public transportation, carpooling, biking, and walking.
How the One Car Challenge Works
Selected participants in the One Car Challenge are required to utilize the GoCarma smartphone application to accurately track odometer readings and travel behavior throughout the five-week program. By keeping at least one household vehicle parked at home and opting for alternative transit methods, participants can earn up to $600, which breaks down to roughly $120 per week. Eligible applicants must be at least 21 years of age and apply online, with the program primarily targeting households that own more than one vehicle, though single-car households are also permitted to apply.
Building on Past Success and Funding
This initiative represents an expansion of a successful 2023 pilot program conducted in the LA County city of Santa Monica. That initial phase involved 300 households and yielded a 16.16% increase in walking, biking, and public transportation usage, according to data from LA Metro. Financial backing for the broader rollout is provided by a $2 million Regional Early Action Planning grant supplied by the Southern California Association of Governments.
Evaluating Future Transportation Policy
According to NBC Los Angeles, transit officials intend to leverage data gathered from the expanded pilot to determine whether incentive-based frameworks effectively reduce vehicle miles traveled. The findings will serve as a long-term transportation demand management tool, guiding future regional policy, optimizing traffic flow, and decreasing vehicle emissions. Key partners collaborating on the initiative include LA Metro, the Los Angeles Department of Transportation, CARB, and Carma.
