The Safety Management System (SMS) provides a structured framework for reducing fatal collisions on roadways. King County demonstrated a significant 60% reduction in fatalities through a systematic, long-term safety strategy developed over ten years. The program incorporates the "Four E's"—Education, Engineering, Enforcement, and Emergency Medical Services—targeting key collision types and locations. By prioritizing data collection, action plans, and evaluating outcomes, the SMS presents a proactive approach for improving transportation safety and securing funding for necessary improvements.

  2. SAFETY MANAGEMENT SYSTEMS -FATAL COLLISION REDUCTION Northwest Tribal Transportation Symposium May 5-7, 1999 Portland, Oregon

  3. SAVE LIVES ON YOUR TRANSPORTATION SYSTEM??? If you could reduce fatal collisions on your roadway by 60%, would you?

  4. 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.

  5. 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.

  6. 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.

  7. 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%

  8. 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.

  9. Safety Management System Program Direction Cont: • Prioritize - see “Local Agency Safety Management System”. • Implement. • Evaluate success and feed back results to step 4.

  10. 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

  11. Design/Collision Considerations - Roadway Factors: • Shoulder Width and Condition • Pavement Condition/Type • Delineation and Signing • Alignment of Roadway • Intersection Present

  12. Design/Collision Considerations - Roadway Factors Cont: • Pavement Drainage • Driver Expectancy • Clear Zone Issues • Weather Factors • Roadway Width

  13. Design/Collision Considerations - Roadway Factors Cont: • Traffic Volume • Access Issues • Speed Limit • Traffic Mix • Lighting

  14. Collision Considerations - Vehicle Factors: • Visibility • Tire Type • Vehicle Age • Farm Vehicles • Pickups/SUV’s

  15. Collision Considerations - Vehicle Factors Cont: • Braking Ability • A-Post Visibility • Vehicle Loading • Mechanical Failure • Vehicle Blind Spots

  16. 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

  17. Collision Considerations - Human Factors: • DWI • Seat Belts • Inattention • Drowsiness • Inexperience

  18. Collision Considerations - Human Factors Cont: • Loss of Acuity • Perceived Shy Distance • Perception Reaction Time • Speeding/Aggressive Driving

  19. Areas to Look at to Reduce Collisions: • Weather • Location • Roadway Surface • Roadway Geometrics

  20. 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)

  21. 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.

  22. 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!
