Outside car companies, few facilities in the world are equipped to
conduct the range of crash tests and other research the
Vehicle Research Center can accommodate.

Overview
Š Research on turning knowledge into action?
– Hope (hypotheses) into policy
Š Dr. Susan Ferguson
Dr. Robyn Robertson
– Specific examples of research now being conducted
to turn hopes into results
Š Emphasize other areas where already we know what
works –
– Just waiting for the politically astute – or clever –
among you to put them into action
IIHS
IIHS mission is to use research to identify ways
to reduce deaths, injuries, and property
damage from motor vehicle crashes
Š Focus is on applied research
– Define problems
– Identify countermeasures
– Evaluate countermeasures
– Understand why effective countermeasures
are not widely used
IIHS
Funded entirely by U.S. auto insurers
The Insurance Institute for Highway Safety is an independent,
nonprofit, scientific and educational organization dedicated to reducing
the losses — deaths, injuries, and property damage — from crashes on
the nation's highways.
founded in 1959
The Highway Loss Data Institute shares and supports this
mission through scientific studies of insurance data representing the
human and economic losses resulting from the ownership and operation
of different types of vehicles and by publishing insurance loss results by
vehicle make and model.
founded in 1972

The traffic environment is “your baby”
Š Road user behavior
Š Traffic engineering
Š Any effect here depends on state and local action
– IIHS and the federal government can help with info
and (from the government) money
– But the political will must come from you, talking to
your constituents

Traditional sobriety checkpoints
IIHS
Enforcement barriers
Š Resources (money, personnel, equipment)
Š Complexity of the arrest process
Š Knowledge about and buy-in to what works
Š Motivations, attitudes, priorities
IIHS
Dealing with the barriers
Š Smaller (4-5 person) checkpoints
Š Enhanced training in arrest procesures, in providing
testimony
Š Equipment that facilitates enforcement, e.g., in-car
videos, PBTs, passive alcohol sensors
Š Computerized forms, digital dictation systems that
reduce paper work and recording errors

Intersection crashes

– 5 crashes per minute
– 1 serious injury crash every 6 minutes
– 1 fatality per hour

IIHS
Roundabouts are circular intersections with design features
that eliminate the need for stop signs or traffic signals
IIHS
Estimated crash reductions if 10 percent of
intersections in US converted to roundabouts
Š Approximately 78,000 crashes prevented annually,
including:
– 500 fatal crashes
– 50,000 injury crashes
IIHS
Estimated annual economic savings if 10 percent
of intersections in US converted to roundabouts
Š Vehicle delays reduced by about 8 million hours
Š Fuel consumption reduced by more than
5 million gallons
