slide 2: California's Strategic Highway Safety Plan

slide notes:

Who is part of CA14. How often do we meet. How do we meet.




slide 3: The SHSP is Data Driven

  • Work Zone Challenge Area goal:
    By 2010, reduce fatalities in California work zones by 10% from their 2004 level (109).
  • Each action was to be attainable, measurable, and focused on a known problem area.

slide notes:

UC Berkeley worked with us to supply data. But we really didn't have much. One thing we learned was that 26% of all work zone fatalities occur as a result of end of queue collisions.




slide 4: Original Actions Are All Complete

  • 14.01 Joint work zone training for CHP and Caltrans.
  • 14.02 Improve collection & analysis of work zone crash data.
  • 14.03 Encourage use of dynamic merge systems to reduce end of queue collisions.
  • 14.04 Permanently fund Slow for the Cone Zone campaign.

slide notes:

None.




slide 5: Original Actions Are All Complete

  • 14.05 Encourage use of more and better mobile barriers and attenuators.
  • 14.06 Increase work zone training for all workers.
  • 14.07 Encourage use of full closures.
  • 14.08 Develop lane closure data system.
  • 14.09 Encourage use of Safety Edge.

slide notes:

None.




slide 6: Original Actions Are All Complete

  • 14.10 Evaluate work zone language in driver handbook and recommend changes.
  • 14.11 Change new product evaluation system to speed use of innovative products.
  • 14.12 Develop typicals and guidance for bikes & peds in work zones.
  • 14.13 Project specific websites.
  • 14.14 Best practices for purchasing new technology.

slide notes:

None.




slide 7: Latest Data

  • Actual number in 2010 was 41 equal to a 62% reduction.
  • The total number of fatalities has fallen each and every year since 2007.
  • New data suggests most crashes occur near activity area not the transition area.
  • New data suggests most crashes are due to improper lane changes and following too close/ excessive speed.

slide notes:

None.




slide 8: What Worked?

  • Highway Safety Improvement Program (HSIP)
    • SAIC study examined the nationwide reduction in roadway fatalities.
    • Isolated trends due to seat belts, safer vehicles, etc.
    • Found that for every $1 million obligated, societal costs of $24 million were saved.

Chart shows that the traffic fatality rate from 2000 to 2009 fell from about 43,000 to about 34,000, while the annual safety obligation rate increased from about $500 million in 2003 to about $1.2 trillion in 2008.

slide notes:

None.




slide 9: What Worked?

  • Importance of collaboration.
    • 4 E's were essential.
    • Participation by industry and community stakeholders.
    • All contributed to a more effective plan, a more workable plan, and commitment across the board.

slide notes:

None.




slide 10: What Worked?

  • Importance of Buy-In from Leadership
    • Each agency commits resources up front to see it is completed.
    • In some cases multiple agencies may contribute funding.
    • As problems are encountered leadership helps find ways around them.

slide notes:

None.




slide 11: What Worked?

  • Some actions became possible that were not without the SHSP.
    • Multi-year funding for Slow for the Cone Zone.
  • Interagency actions are more cooperative.
    • Training for law enforcement in work zones.

Logos for Caltrans, California Highway Patrol, California Office of Traffic Safety, and the California Division of Motor Vehicles.

slide notes:

None.




slide 11: What's Next?

  • One new action approved: 14.15 Work Zone Tool Kit
  • More in development:
    • Transverse rumble strips.
    • Continued and improved data collection.
    • Speed reduction techniques for maintenance.
  • Detailed data will help us identify problems and better target our efforts and resources.

slide notes:

None.
