Goals of the SurveyProvide area residents with an additional
opportunity for meaningful input on a
controversial neighborhood issue
Give as many people as possible across
the array of stakeholders the chance toexpress their opinions
Identify concerns with the project
Identify potential modifications

Caveats Not intended as a referendum or a randomly-
sampled public opinion poll
- Goal was to provide an additional opportunity for input toas many people as possible
Survey was used as an organizing tool bysupporters & opponents
- Still, over 3,000 people participated, far beyond organized
networks
Risk of duplicate surveys
- We took substantial steps in post-survey data analysis to
conduct integrity tests -- duplicate surveys that were likelyfrom the same individuals were eliminated
- 227 Non-Brooklyn respondents and 93 suspicious responseswere removed from final results

Key Points
Among respondents from Park Slope (beyond PPW)and elsewhere in Brooklyn, there is broad supportfor the project
Among respondents living on PPW, there is aroughly even split between those wishing to keepthe bike lanes & those wishing to eliminate them
Important concerns emerged, especially around
pedestrian/bike interactions, as well as parking andaesthetics
Modifications could address many of the mostpressing concerns
Responses highlight a wider need for enforcement,education, and culture to address expansion ofcycling

Goals & Safety Perception Conclusions
Pedestrians & bikers
report overall safetyimprovements
Bikers feel much safer
with physicallyseparated lane
Crossing at signalized
intersections feels saferbecause of slowerspeeds and narrowedtraffic lanes
Improvements in Perceived Safety
"It is finally safe to ride a bike on PPW. You no longerhave to bike on the sidewalk or ride on 8th Avewhere two cyclists have been killed in the last couple
of years."
I liked driving fast on PPW and now I have to go alittle slower, but it's not a major difference. Two lanesis plenty to handle the traffic there.
"My kids have become more interested in biking! Thebike path has given a certain respect to bikers that I--
and my children--really appreciate."

Pedestrian/Bike interface is
problematic
People exiting cars feel
vulnerable
Perceived Safety Issues Highlighted by Survey
Some cyclists may not be aware or considerate about
yielding to pedestrians and that needs to be enforced.
Signals are not clear. If the light is red and the bike lane
signal is yellow, am I supposed to go slowly or yield to
pedestrians?
"[I] nearly got clobbered by a bicycle the other day when I
accidentally stepped back into the bike lane after strapping
the baby into her car seat."
[My] biggest area of concern is pedestrians not looking for
bikes coming when crossing. Bikers need to be more aware
of pedestrians."

Increase Enforcement & Safety Awareness
Enforcement is key Bikers must yield to pedestrians and stay off sidewalk
Double parking should be enforced Cars must not park in ped areas, bike lanes, or loading zones
Expand and enforce loading zones where needed toaccommodate demand at hotspots
Convene neighborhood town halls on street safety
Need to reinforce rules and do more to educate, expect,and enforce compliance especially for cyclists, as wellas street safety in general

Conclusion
Among respondents, there is broad support
While there is a notable minority that strongly disagrees,most respondents believe the project has met its goals, andfeel that it has made them safer
There are meaningful modifications that canimprove the project and address concerns
Improve safety, especially pedestrian-bike interface
Improve aesthetics
Address parking & loading
Enforce rules of the road
There are deep and passionate feelings that extend
beyond the most committed activists We need to address bike enforcement/practice & safety aswell as a broader dialogue about improving street safetyfor everyone
