SYSTEMS FATAL COLLISION
REDUCTION
Northwest Tribal Transportation
Symposium
May 5-7, 1999 Portland, Oregon
SAVE LIVES ON YOUR
TRANSPORTATION
SYSTEM???
If you could reduce fatal
collisions on your roadway by
60%, would you?
Impossible you say???

King County attained a 60% reduction in
fatal collisions on their roadway system.

They implemented a systematic, long term
approach toward safety.

The improvements along their roadways
took place over a ten year period.
What IS a:
Safety Management System???

A method to reduce fatal collisions on
roadways. With the reduction of fatal
collisions, all collision types will in turn, be
reduced on transportation systems.

A system to obtain funding for roadway and
safety improvements.
Why a:
Safety Management System???

It provides a systematic, long term approach
to fatal collision reduction.

Local Agency and TransAid support for the
Safety Management System.

Four “E’s” are used in the program Education, Engineering, Enforcement and
Emergency Medical Services.
Top Causes of Fatal Collisions in
Washington State Counties:
Fixed Object - 37.5%
 Vehicle Overturn - 15.4%
 Entering at Angle - 11.9%
 Head-On - 8.8%
 Opposite Direction/All Others - 7.5%
 Pedestrians - 7.1%

Safety Management System
Program Direction:
 Collect
data for top collision types.
 Identify
locations/corridors where these
accidents occur.
 Rank
locations/corridors.
 Develop
multi-disciplinary action plan, as
appropriate.

Design and Collision
Considerations:
When looking at fatal collision reduction,
there are three factors that can contribute to
the collision. These factors are:

Human

Vehicle

Roadway
Design/Collision Considerations
- Roadway Factors:

Shoulder Width and Condition

Pavement Condition/Type

Delineation and Signing

Alignment of Roadway

Intersection Present
Design/Collision Considerations
- Roadway Factors Cont:

Pavement Drainage

Driver Expectancy

Clear Zone Issues

Weather Factors



Perceived Shy Distance

Perception Reaction Time

Speeding/Aggressive Driving
Areas to Look at to Reduce
Collisions:

Weather

Location

Roadway Surface

Roadway Geometrics
Areas to Look at to Reduce
Collisions Cont:

Date, Time and Day of Week

Daylight/Lighting Conditions

Drive Profile (age, in-state or out)
The Transportation Safety
Movement ….

Within the Pacific Northwest and on a
national level, the greatest safety efforts
continue to be directed at the SAFEST
transportation systems - the Interstate and
State Highway systems.
Redirecting the Transportation
Safety Movement ….

The redirection of Transportation Safety
focus to the other systems needs to begin.

There are roadways that have higher fatality
rates than either the Interstate or State
Highway transportation systems.

These systems MUST receive national
recognition and funding to bring up their
safety standards!
