San Francisco's Smart City Challenge

San Francisco is meeting the Department of Transportation's Smart City Challenge to bring the future of shared, electric, connected, and automated vehicles to all San Franciscans. Together we can build a transportation system that is safer, cleaner, more accessible and more affordable. This will be a system that provides opportunities for San Franciscans to climb the economic ladder and connect with their neighbors.
