The concepts are being explored because Bart expects passenger numbers to increase by 50% by 2025, driven in part by the extension of the network to San Jose.
"This our way for planning for the future and the massive growth this region is expecting in the next 10 to 15 years," Bart spokesperson Mrs Alicia Trost told local media. "It's not just about increasing services; it's also about becoming much more efficient and reducing greenhouse gases, and it's about economic development in the Bay Area."
In addition to the revised service patterns, Bart is also exploring the possibility of increasing off-peak and weekend frequencies.
