Context-sensitive transportation
planning seeks to develop a
transportation network “…that
complements its physical setting
and preserves scenic, aesthetic,
and historic and environmental
resources while maintaining safety
and mobility.”
Circulation Networks
Circulation Networks
Circulation systems for pedestrian use can be designed in geometric pattern
to strengthen the built environment’s spatial organization:
* Linear Pattern (walkways are commonly used for recreational paths; may run
parallel to the shoreline and other natural features)
* Grid Pattern (walkways parallel the street network in urban areas;
advantages include ease of orientation and flexibility in route selection)
* Loop Pattern (walkways may organize a series of linked open spaces, a
cluster of buildings, or other activity nodes)
* Radial Pattern (walkways converge to form intersections that become
plazas, squares, or other important pedestrian nodes)
* Spiral Pattern (walkway ceremonially descends or ascends toward a special
place such as a sculpture garden, a memorial, or another contemplative
outdoor space)
__________and __________ can
also reduce costs for hearing and
cooling buildings and for
managing stormwater runoff.
Green roofs and rain gardens
providing opportunities
for social interaction
Nodes
providing opportunities
for quiet respite
Oases
providing opportunities
for prospect with a refuge
Niches
Pedestrians “desire lines” are satisfied by
conveniently linking common destinations
(for example, building entrances, transit
stops, parking lots, and plazas).
Connectivity
A hierarchy of walkways are of
sufficient size to accommodate
expected pedestrian traffic.
A hierarchy of plazas, seating areas,
and other “outdoor rooms” are
conveniently located (for example, at
building entrances, walkway
intersections, waterfront promenades).
Capacity
Special paving that helps to define
pedestrian spaces at major building
and site entrances, and at major
pedestrian walkways and intersections.
