Park-and-ride is a transportation system designed to reduce traffic congestion in urban areas. It allows commuters to park their vehicles in designated lots located outside the city and then use public transportation, such as buses or trains, to reach their final destination. This system encourages the use of public transit and helps minimize the number of cars in busy city centers. Typically, park-and-ride facilities are strategically located near major highways or transit lines, making them easily accessible. Many cities, including Los Angeles and London, have implemented park-and-ride programs to promote sustainable commuting and improve air quality by decreasing vehicle emissions.
