Green and sustainable cities present fundamental opportunities to both apply new technologies, such as public transit, greening community spaces & green building designs along with bringing about major lifestyle changes such as walking, bicycling and reductions in consumptions.
Principle 1: Manage CongestionCongestion is a fact of life in successful urban places. By definition, a place that supports a great concentration of economic and social activities within a pedestrian-scaled environment is going to be congested. Principle 2: Balanced/Active StreetsDowntown streets must balance the needs of pedestrians, bicycles, transit and the automobile in creating an attractive and viable urban core. Downtown streets are for people first, commercial second, parking third and through traffic fourth.Principle 3: Streets as PlacesThe Great Streets Program envisions downtown as a vital focus of city life, and as a primary destination. Our downtown streets are our most important and pervasive public space and common ground.Principle 4: Interactive Streets Urban Streets are the stages on which the public life of the community is acted out.Principle 5: Pride of PlaceVisible, caring and upkeep are critical to the vitality of urban street life.Principle 6: Public ArtArt in the public environment can help to establish a stronger sense of place and a continuity between the past, present and future.

EVOLUTION OF THE URBAN FORM
"Mother had given a couple of
parameters: the division of the city into
four areas, or zones, and the number of
people for whom the city is envisaged
(50.000). The division into those four
zones (industrial, residential,
international and cultural) is unique, and
has no precedent in town planning.
Four-part master plan idea by Mirra
Alfassa, "the Mother“ of Auroville.
1967 Galaxy Master Plan
• Auroville is an attempt to
develop a utopian city with an
ideal community and self
sustenance were the driving
force would be to realize human
unity in diversity.
• This concept reflects in the city
planning which integrates the
new age metropolis as a mean
to exercise ecological
sustenance in living.
• The Green Belt is a fertile zone
for applied research.
• The resulting innovative
methods can be
applied/extended in both rural
and urban areas everywhere.
