The Bay Area Rapid Transit (BART) is a public transportation system serving the San Francisco Bay Area in California. It connects cities like San Francisco, Oakland, and Berkeley through a network of trains and stations, making it easier for commuters to travel across the region. BART began operations in 1972 and has since expanded to cover over 100 miles of track. The system is known for its efficiency and convenience, providing a reliable alternative to driving. BART trains run frequently, especially during peak hours, helping to reduce traffic congestion in the densely populated Bay Area.
