When there is a balanced combination of complementary activities in a given neighborhood (meaning a mix of housing, workplaces, commerce, and services), a significant portion of its residents' daily trips can remain short and walkable. Diverse uses, with different peak hours throughout the day, help keep streets busy and safe for longer, stimulating pedestrian and cyclist activity and promoting a lively human environment where people want to live. This also helps balance public transit demand, resulting in a more efficient and sustainable operation over longer periods of the day. People of all age groups, genders, and income levels can safely interact in public spaces.
