37. Objective
● Utilize New York motor vehicle collision data
● Surface creative ideas that could help reduce accidents in Brooklyn
Dataset
● Bigquery-public-data:new_york.nypd_mv_collisions
● Analysis based on 2013 - 2017 data.
Target Audience
● Brooklyn City Council and Urban Safety Leaders
38. Brooklyn Motor Vehicle Accidents Overview
● Total number of police reported accident injuries have dropped by 29% and fatalities have dropped by 39% (2013 vs
2017). Yet, there’s still room for improvement as 41 people were killed in 2017 (10 person increase from 2016).
● In 2017, roughly half of the fatalities from motor vehicle accidents were pedestrians.
● The three most common contributing factors to accidents with injuries were driver inattention/distraction, failure to yield
right-of-way, and traffic control disregarded (2017). It’s likely that cell phone usage while driving is influencing these driver
errors.
Ideas to increase safety for Brooklyn community members (with a core focus on pedestrian safety):
1. Launch targeted education / solutions for neighborhoods that are in areas with high density of pedestrian
injuries.
2. Around the most dangerous intersections, increase police visibility and utilize a branded social media
hashtag (i.e. #BrooklynVisionZero) to further crowdsource safety improvement ideas.
3. Increase ticketing and laws for distracted driving. Provide community members free *safety branded* phone
accessories for completing distracted driving education course.
Executive Summary: Ideas to reduce motor vehicle accidents and achieve Vision
Zero (e.g. zero fatalities from motor vehicles in Brooklyn)
38
39. With Vision Zero initiatives across
New York City, progress has been
made on lowering the number of
fatalities and injuries from motor
vehicle collisions.
In Brooklyn, we see a gradual decline year over
year in total number of reported injuries.
2016 was the five year low in motor collision
fatalities. However, in 2017 the trend reversed
with 10 more fatalities than 2016.
Incorporate learnings from 2016 to inform future
safety measures.

1 Brooklyn is the largest borough by population (2.65M in 2017).
40. Pedestrians are at the highest risk
of being killed in a motor vehicle
collision.
On average, between 2013 and 2017,
57% of accident fatalities were
pedestrians.
Given finite resources to reduce
accidents, it’s recommended to
prioritize enhancing pedestrian
safety as the core focus of new
projects/legislation.

41. Launch targeted education /
solutions for neighborhoods that
are in areas with high risk/density
of pedestrian injuries.
1) Partner with social media influencers on
pedestrian safety education campaigns.
1) For older demographics, design targeted
mail education resources + hand out
resources in the community.
1) Continue school education programs on
street crossing safety.
1) Embed flashing sensors in the crosswalk
that warn peds of an oncoming vehicle.
Use sound alarms/sensors to alert
jaywalkers of illegal behavior.

42. ● Community members could
share a photo on social media
and tag the photo with the
safety branded hashtag.
● The post description could
contain the safety improvement
idea. Each month Brooklyn city
council could share prizes or
spotlight top ideas.

Number of Reported Injuries
10 Most Deadly Intersections
in Brooklyn (2013 - 2017)
1 Fatalities and injuries represent an aggregate of (Motorists, Cyclists, Pedestrians).
Around the most dangerous
intersections, increase police
visibility and utilize a branded
social media hashtag campaign
(i.e. #BrooklynVisionZero)
to further crowdsource safety
improvement ideas.
43. Increase ticketing and laws for distracted driving. Provide citizens free *safety
branded* phone accessories for completing distracted driving safety course.
431 Reported injuries represent an aggregate of (Motorists, Cyclists, Pedestrians).
● Highlighted are four accident
contributing factors that are
increasing in reported frequency vs
previous years.
● It’s likely that mobile phone usage is
influencing the rise of these
*distraction related* driver /
pedestrian errors.
● Increase ticketing/law robustness for
mobile phone usage while driving
and crossing streets.
● Incorporate mobile phone
distractions as a segment of the
driving safety course.
44. Recap of ideas to increase safety for Brooklyn community members:
1. Launch targeted education / solutions for neighborhoods that are in
areas with high density of pedestrian injuries.
2. Around the most dangerous intersections, increase police visibility and
utilize a branded social media hashtag (i.e. #BrooklynVisionZero) to
further crowdsource safety improvement ideas.
3. Increase ticketing and laws for distracted driving. Provide community
members free *safety branded* phone accessories for completing
distracted driving education course.
Conclusion: Continued focus on pedestrian safety saves lives!
Additionally, measures that improve pedestrian safety also have positive
influence on reducing overall frequency of motor vehicle accidents.
