the street is valuable public space &
should be shared by all users.
traffic calming:
Traffic calming measures were popularized in Europe in the 1970s thus coined the dutch term ‘woonerf’ as a
reaction to the growing dominance of automobile over bicycles. Blurring the boundary between street and sidewalk,
woonerfs combined innovative paving, landscaping and other urban designs to allow for the integration of
pedestrians, cyclists and slow-moving cars. It uses combination of mainly physical measures that reduce the
negative effects of motor vehicle use, alter driver behavior and improve conditions for non-motorized street cars
woonerf:
Woonerf translates roughly as
"street for living," it was first
employed in 1976 Netherland
by Dutch traffic engineer Hans
Monderman, a streetscape
stripped of lane markers,
curbs, sidewalks, zebra
crossings and other obvious
boundaries denoting spaces
meant for single forms of
transportation. Downtown
areas were then converted to
pedestrian areas. Although it
might seem counterintuitive,
this integration naturally
altered driving behavior and
reduced the number of
accidents across Europe.
a street for living:
1. Road humps & speed
tables
2. chicanes
3. Traffic throttles
(pinch points)
4. Curb extension
5. Central refuges
6. Traffic circles
7. Textured surface
8. Shared surfaces
9. Rumble strips
_to reduce the severity and the
number of accidents in built up
areas
_ to reduce air and noise
pollution
_ to improve the urban street
environment for non-motor users
and to reduce the car's
dominance in ways that vary

+ overall vehicle traffic volumes decreased,
particularly on the community streets.
+ vehicular traffic coming into the area
decreased.
+ pedestrian and bicycle traffic volumes rose
along most routes.
+ average vehicle speeds fell by 3.5 km/hr (2
mi/hr), with a much greater fall in the
maximum speed of cars
+ parked cars became less intrusive.
+ traffic accidents fell from 32 in the 4 years prior
to the project to just two in the First 2 years
following implementation.
_travel time and distance for all users are
increased
_local residents are diverted to other streets,
visitors and delivery services are confused and
delayed
_emergency vehicle response can be delayed

3 Traffic calming techniques are exercised
along broadway which tends to create
1. Times square traffic as it intersect with crossing
2. Herald square avenues, blockage improve the flow of
traffic by reconnecting the grid.

4. Allen and Pike St. eliminated by filling the streets with
pedestrian malls to control traffic.
manhattan:
broadway is closed to vehicles from 47th Street to 42nd
Street. Traffic would continue to flow through on crossing
streets, but the areas between the streets would become
pedestrian malls, with chairs, benches and cafe tables with
umbrellas.
