proliferation of concrete barriers to guard against truck bombs
makes downtown seems like a war zone. Sturdy, federally crash-rated, fixed
security bollards protect critical infrastructure yet are more space
efficient and attractive. These cost effective and durable bollards should
also be used to widen Lower Manhattan’s congested sidewalks and protect
pedestrians at dangerous intersections.
Concrete barriers, St. Thomas St., protect buildings, but block sidewalks
and create a hostile atmosphere.
Impenetrable, space efficient bollards installed in front of the federal
courthouse on Centre St. after the first
new secure areas, and pedestrian zones with retractable bollards.
Retractable bollards controlled by EZ-Pass style transponders
raise and lower to allow authorized service and emergency vehicles quick
access to restricted areas. Business owners can also use pass cards to let
less frequent delivery vehicles through. Retractable bollards are used in
City Hall Park and in hundreds of French, English, and German cities and

protect the Stock Exchange. Retractable bollards would be more secure,
attractive, cost effective, and space efficient.
Two retractable bollards in front of a gate to City Hall raise and lower
instantly as needed.
Sidewalk space is at a premium downtown, so perimeter security
(vehicle barriers) must be unobtrusive and passable by
pedestrians. Fixed, federally crash-rated bollards have much
smaller footprints than planters or concrete barriers.
Fixed bollards are used In several locations in NYC to widen
sidewalks and guide vehicles to the safest path. NYC should also
use them to widen sidewalks downtown where crowding is worst.
Fixed bollards off of 5th Ave. in Manhattan widen the side-walk
to relieve crowding and shorten the crossing distance.
bollards and transponder pass key system
A number of
European cities including Cambridge, UK’s town center and London’s
Square Mile use retractable bollards to control vehicle access and
create pedestrian streets. The system is made up of a series of
bollards connected to a central hydraulic power unit. The bollards
are controlled by a transponder system that reads a transponder
tag inside authorized vehicles (the technology behind EZ Pass).
When activated by a transponder, the bollards retract into the
ground in seconds, and rise as quickly when the vehicles is
through. The system has a failsafe mechanism that allows the
barriers to be manually lowered in the event of a power failure,
as well as a measure to prevent bollards from rising under
placed at intervals of about 5’ to ensure that people in wheel
chairs can pass through, but
