Conceptual Design
Principles :
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.” (United States Federal
Highway Administration 2009)
Circulation Networks
Conceptual Design Principles
Circulation Networks
walkways are commonly used for recreational paths; may run
parallel to the shoreline and other natural features)
Linear Pattern
Conceptual Design Principles
Circulation Networks
(walkways parallel the street network in urban areas;
advantages include ease of orientation and flexibility in route selection)
Grid Pattern
(walkways may organize a series of linked open spaces, a
cluster of buildings, or other activity nodes)
- Loop Pattern
(walkways converge to form intersections that become
plazas, squares, or other important pedestrian nodes)
Radial Pattern
(walkway ceremonially descends or ascends toward a special
place such as a sculpture garden, a memorial, or another contemplative
outdoor space)
Spiral Pattern
Buffering aquatic habitats from
contaminated stormwater runoff from
upland developed areas.
* Creating ecotone habitat for native
plant and animal species.
* Shoreline stabilization and
remediation produced by plantings
to reduce erosion and sedimentation
of water bodies.
Green Infrastructure
Green Infrastructure
- Controlling stormwater at the source
(for example, minimize and mitigate
land development impacts at, or
near the site disturbance).
*Disconnecting impervious surfaces to
increase infiltration and reduce
runoff. - Dispersing drainage from roofs and
other large, impervious surfaces to
lengthen flow paths and encourage
slow, shallow runoff over vegetated,
pervious surfaces. - Using simple, small, nonstructural
methods (for example, grassed
swales and shallow basins with gentle
side slopes, rain gardens).
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 are separated from
vehicles and, where the systems
intersect, walkways are identified with
paving changes, markings, or refuge
islands to reduce pedestrian crosswalk
distances.
Separation
- Pedestrians “desire lines” are satisfied by
conveniently linking common destinations
(for example, building entrances, transit
stops, parking lots, and plazas).
Connectivity
- The number and distance of walkway
interruptions (for example, across large
parking lots) are minimized.
