Traffic safety: Key vehicle and driver behavior factors

1.2 million people killed each year on the world’s roads
Harm from traffic - almost incomprehensible magnitude
Injures vastly outnumber fatalities
Victims mainly healthy young people
![Page 3: Leonard Evans President, Science Serving Society President-Emeritus, International Traffic Medicine Association Bloomfield Hills, Michigan USA Devoted](https://reader038.vdocuments.mx/reader038/viewer/2022110101/56649e865503460f94b89ce5/html5/thumbnails/3.jpg)
Key is knowledge gained from science
What can be done to reduce this enormous harm?
A solid edifice of knowledge exists
Scientific literature since 1930s has papers on traffic safety
Is too often ignored – with tragic results

Captain Edward J. Smith27JAN1850–15APR1912
Safety lessons from sinking of the Titanic
Age when Titanic sailed
62 years 2.6 months Titanic leaving Belfast
2 April 1912
![Page 9: Leonard Evans President, Science Serving Society President-Emeritus, International Traffic Medicine Association Bloomfield Hills, Michigan USA Devoted](https://reader038.vdocuments.mx/reader038/viewer/2022110101/56649e865503460f94b89ce5/html5/thumbnails/9.jpg)
Titanic illustrates central distinction between:-
1. Crash Protection
Given crash occurs, to reduce consequent harm
2. Crash Avoidance
To prevent crash occurring
Did Titanic’s superior crash protection save 705 lives, or cause over 1500 deaths?

Early recognition of distinction between
1. Technology
2. How it is used – driver behavior
![Page 13: Leonard Evans President, Science Serving Society President-Emeritus, International Traffic Medicine Association Bloomfield Hills, Michigan USA Devoted](https://reader038.vdocuments.mx/reader038/viewer/2022110101/56649e865503460f94b89ce5/html5/thumbnails/13.jpg)
Now look at peer-reviewed technical literature
All previous anecdotal
Paper in Amercan Journal of Psychology
![Page 14: Leonard Evans President, Science Serving Society President-Emeritus, International Traffic Medicine Association Bloomfield Hills, Michigan USA Devoted](https://reader038.vdocuments.mx/reader038/viewer/2022110101/56649e865503460f94b89ce5/html5/thumbnails/14.jpg)
“More efficient brakes on an
automobile will not in themselves
make driving the automobile any
safer.”
A Theoretical Field-Analysis of
Automobile Driving, American
Journal of Psychology 1938
![Page 15: Leonard Evans President, Science Serving Society President-Emeritus, International Traffic Medicine Association Bloomfield Hills, Michigan USA Devoted](https://reader038.vdocuments.mx/reader038/viewer/2022110101/56649e865503460f94b89ce5/html5/thumbnails/15.jpg)
Claim that better brakes do not increase safety based on reason alone
But is it possible to address empirically?
Did not happen in
1940s
1950s
1960s
1970s
1980s
then opportunity occurred!
![Page 16: Leonard Evans President, Science Serving Society President-Emeritus, International Traffic Medicine Association Bloomfield Hills, Michigan USA Devoted](https://reader038.vdocuments.mx/reader038/viewer/2022110101/56649e865503460f94b89ce5/html5/thumbnails/16.jpg)
Dramatic advance in brake technology
Increases rollover risk by (39+16)%
Large numbers of GM popular vehicles:
1991 MY – NONE had ABS
1992 MY – ALL had ABS
Otherwise, no important differences
ABS (antilock brakes)
![Page 17: Leonard Evans President, Science Serving Society President-Emeritus, International Traffic Medicine Association Bloomfield Hills, Michigan USA Devoted](https://reader038.vdocuments.mx/reader038/viewer/2022110101/56649e865503460f94b89ce5/html5/thumbnails/17.jpg)
Engineering factors affecting survival in crashes
Biomechanics - the science of relationships between injuries and the mechanical forces that produce them:
Penetrating trauma
Blunt trauma
![Page 18: Leonard Evans President, Science Serving Society President-Emeritus, International Traffic Medicine Association Bloomfield Hills, Michigan USA Devoted](https://reader038.vdocuments.mx/reader038/viewer/2022110101/56649e865503460f94b89ce5/html5/thumbnails/18.jpg)
To reduce severity of blunt trauma – reduce force by reducing deceleration of body
Spread stopping over as much distance, and time, as feasible through
occupant protection devices
vehicle characteristics and design
![Page 19: Leonard Evans President, Science Serving Society President-Emeritus, International Traffic Medicine Association Bloomfield Hills, Michigan USA Devoted](https://reader038.vdocuments.mx/reader038/viewer/2022110101/56649e865503460f94b89ce5/html5/thumbnails/19.jpg)
Scientific study needs data
By far, most reliable data is for fatalities
Even though death just tip of iceberg in numbers, much attention is devoted to it
![Page 20: Leonard Evans President, Science Serving Society President-Emeritus, International Traffic Medicine Association Bloomfield Hills, Michigan USA Devoted](https://reader038.vdocuments.mx/reader038/viewer/2022110101/56649e865503460f94b89ce5/html5/thumbnails/20.jpg)
Fatal Accident Reporting SystemName changed
Feb. 1998
Census of all US traffic crashes in which anyone is killed on a public road
Run by US National Highway Traffic Safety Administration (NHTSA)
Data from 1 January 1975
Over 1.6 million fatalities documented through 2013

The vehicle factor having largest influence on occupant risk is:
Vehicle mass (weight) and size

What is the casual role of mass and size?
Am I safer if I put bricks in my trunk?
Does NOT answer
How does change in RELATIVE risk affect each driver individually?
![Page 33: Leonard Evans President, Science Serving Society President-Emeritus, International Traffic Medicine Association Bloomfield Hills, Michigan USA Devoted](https://reader038.vdocuments.mx/reader038/viewer/2022110101/56649e865503460f94b89ce5/html5/thumbnails/33.jpg)
If cars differ only in mass, R = μu
If cars differ in another attribute, say one carries additional cargo
R = probability of accompanied driver fatality in car1
probability of lone driver fatality in car2 R = A μu

CONCLUSION
Addition of passenger changes driver fatality ratio by
-(14.5 ± 2.3)%
BUT
We do not know how much of this change is a risk reduction to the accompanied driver and a risk increase to the lone driver
To answer, we model process

Effects of speed
1. Risk of crashing increases with increasing travel speed
2. If crash occurs, risk of injury increases with increasing speed
3. If injury occurs, risk that it is fatal increases with travel speed
1% increase in travel speed increases the risk of a fatal crash by at least 4%

Because fatalities reach a maximum number, we can define a simple ratio:
Dimensionless (no units) No arbitrary assumptions Depends ONLY on fatalities
Fatalities in a given yearMaximum yearly fatalities
Plot* how this ratio varies in time after maximum is reached
-------------*on logarithm scale, and x100 to express as %

This is 83.7% below The Netherlands’ all time high of 3,506 in 1972
The Netherlands had 570 traffic deaths in 2013
If US total had fallen by 83.7% from its high, US total in 2013 would be 8,875
(instead of 32,719 observed)
More than 20,000 additional Americans are killed annually because US fails to match decline in Netherlands (+ 10 other countries)

This study, in agreement with earlier research, implies that there are over 200,000 annual traffic deaths in China.
How can this number be reduced?
Two recommendations
Conclusion
![Page 89: Leonard Evans President, Science Serving Society President-Emeritus, International Traffic Medicine Association Bloomfield Hills, Michigan USA Devoted](https://reader038.vdocuments.mx/reader038/viewer/2022110101/56649e865503460f94b89ce5/html5/thumbnails/89.jpg)
1 Create data-collecting agency
USA data set FARS is good model
2 Create traffic-safety research organization
Goal - accuracy and completeness
Supported by government, but largely independent of government
Best model is SWOV in the Netherlands
Make solicited and unsolicited science-based recommendations
Evaluate safety programs (implementation and evaluation must be kept separate)
Goal – highest quality objective scientific research
40+ years of ongoing improvement Free, comprehensive, and simple on web

Concluding comments
Traffic causes enormous numbers of injuries and deaths
Traffic-safety science can sharply reduced these numbers
Reliable data
