TRANSCRIPT
Saving Lives with Sustainable Transport!
! Nicolae Duduta, Associate Transport Planner, EMBARQ, World Resources Institute!
! December 5, 2013 — Washington, DC!
Calz. Independencia, Guadalajara, Mexico - 2009
What are the safety impacts of reducing car traffic and promoting transit, walking,
and cycling?!
How do we better integrate safety into transportation planning?!
Main questions!
! Different approaches to traffic safety!
! Motivation for the report!• Example: Rio de Janeiro — The place of safety in transport
planning!
! Report findings!• Evidence of the safety impact of sustainable transport!
! Outcomes!• Example: Mexico City — integrating safety into transport
planning!
Agenda!
! Pre-crash | Crash | Post-crash!
! The three E’s: !• Engineering!• Enforcement!• Education!
! EMBARQ: Safety should be an integral part of all stages of urban transportation planning!
Approaches to traffic safety!
! Traffic Safety and Sustainable Transport!
! Road Safety Community à WHO, UNRSC!• Decade of Action on Road Safety!• Global Status Report on Road Safety!
! Transport planning!• Planning and engineering professionals!• Local decision makers!
Approaches to traffic safety!
! 300 ft (100m) wide! ! ! ! !!! 50mph (80km) speed limit!! 1,800ft (600m) blocks ! ! !!
The place of safety in transport planning
Rio de Janeiro, Brazil. Photo by EMBARQ.
Sidewalk provision is at the discretion of property owners along the street. Streets often lack sidewalks.
From the time of pressing the button, until finishing the crossing:
8 min, 14 s
Pedestrians almost always cross on red
Safety impact:!! Reductions in traffic (congestion charging)!! Improvements to cycling and pedestrian
infrastructure!! Investment in high quality mass transport!
Report Overview!
! There is a strong correlation between VKT and safety!! Policies that reduce VKT have been shown to also have a
positive safety impact!
Vehicle kilometers traveled (VKT)!
Traffic volumes and traffic safety!

! London introduced a charge for driving a car inside a specific area within the downtown!
! 15% reduction in injury accidents compared to citywide trends in London!
Congestion Charging!
Cycling and safety!
! In several cities around the world, increases in cycling were associated with reductions in the cycling injury rate!
! Examples from Copenhagen, New York, Minneapolis!

Mass transport and traffic safety!
! In the developed world, mass transport is the safest urban transport mode!
! In the developing world, well designed, high-quality mass transport systems have had significant safety benefits!
! Calz. Independencia, Guadalajara, Mexico - 2007!
Mass transport!
! Calz. Independencia, Guadalajara, Mexico - 2009!
Mass transport!Reduction in the number of lanes
Shorter pedestrian crossings
Central median
Existing buses and minibuses replaced with a single operating agency
Evidence of safety impact from: !! Reductions in car traffic (e.g. congestion charging)!! Improvements in cycling infrastructure and increases in
cycling volumes!! High quality mass transport systems (including evidence
from the developing world)!
! Reductions in exposure, improvements in infrastructure!
Conclusions!
Counterflow – Mexico City!
! Eje 3 Oriente, Mexico City, July 2011!
! Road safety audits: three between 2010-2013 recommended removal of counterflow!
! Safety impact of counterflow: +75% all crashes, +125% injury crashes!
! Design recommendations, workshops with city and transit agency!
Counterflow – Mexico City!
Counterflow – Mexico City!
