Township level:
•The aim was to create a central spine. The master plan was informal with
interlinked space of cultural context, maintenance of hierarchy of road,
open spaces, a central location of basic community services.
•The central spine was a focus of the converging six sectors
Six Sector level:
•This enabled segregation of pedestrian and vehicular movement, goo
distribution of built and unbuilt spaces by promoting interactive land use.

ROADS
• Segregation of vehicular and
pedestrian traffic
• Offsets break visual monoton
• Hierarchy is based on the
volume of the traffic and
activities
•The roads suit human scale
•Use of cul-de-sacs to avoid
traffic

13. CIRCULATION AND LINKAGES
For clear segregation of vehicular
and pedestrian traffic:
•Vehicular access in the form
rectilinear and formal roads in the
hierarchy of 4.5m wide to 15m
wide road draw the vehicles
outwardly.
•Pedestrian access in the form of
informal interlinked open spaces
draws people inwardly.
Vehicular roads
Informal pedestrian pathways and open
spaces

14. HIERARCHY OF OPEN SPACES

• Continuous system of open spaces is
provided
• Staggered roads create
