Streets can accommodate a variety of travel modes while also serving as public amenities, sites of commerce and green spaces. Vehicular roadways should be no bigger than necessary for their function, and they should apportion space safely among private vehicles, transit, bicycles and parking. If they are well designed, streets can move significant volumes of auto traffic and still support other activities. Small streets are equally important and can limit vehicular speeds and capacity in the service of other functions, from deliveries to social activity.
From The City of San Jose's Envision 2040 General Plan:
“A complete street provides safe, comfortable, attractive and convenient access and travel for pedestrians, bicyclists, motorists and transit users of all ages, abilities and preferences. The design of a complete street considers both the public right-of-way and the land uses and design of adjoining properties, including appropriate building heights and the planning of adjoining land uses that actively engage the public street realm.”
