SAFETY MANAGEMENT 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.
Safety Management System Program Direction Cont: • Prioritize - see “Local Agency Safety Management System”. • Implement. • Evaluate success and feed back results to step 4.
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 • Roadway Width
Design/Collision Considerations - Roadway Factors Cont: • Traffic Volume • Access Issues • Speed Limit • Traffic Mix • Lighting
Collision Considerations - Vehicle Factors: • Visibility • Tire Type • Vehicle Age • Farm Vehicles • Pickups/SUV’s
Collision Considerations - Vehicle Factors Cont: • Braking Ability • A-Post Visibility • Vehicle Loading • Mechanical Failure • Vehicle Blind Spots
Collision Considerations - Vehicle Factors Cont: • Visibility Of Vehicles • Vehicle Turning Agility • Differential Vehicle Size • Vehicle Size, Shape and Material • PU/SUV’s More Susceptible to Overturns
Collision Considerations - Human Factors: • DWI • Seat Belts • Inattention • Drowsiness • Inexperience
Collision Considerations - Human Factors Cont: • Loss of Acuity • 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 • Drug and Alcohol Involvement • 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!
