High-quality and convenient transit depends upon high levels of ridership. High demand for transit depends upon on regional development patterns, real estate markets, and urban design that support transit.
Density is critical for the transit system because it concentrates trip origins or destinations so that sharing rides becomes practical as well as economical. A diversity of land uses at destinations means that transit can serve multiple purposes (employment, shopping, and recreation), increasing the system’s efficiency and its convenience for transit riders. The design and orientation of buildings and public spaces matters so that walking is not only safe but rewarding.
