traffic control field reviews8
Traffic Control Field Reviews
  • Flagging Issues
    • Poor operation, No escape route
traffic control field reviews12
Traffic Control Field Reviews
  • Non-Conforming Devices
traffic control field reviews13
Traffic Control Field Reviews
  • Recommendations
    • Need for flagger training
    • Address access issues during project staging
    • Use quality guideline for devices & compliance
  • 2009 work zone reviews
    • BHO & others will review work zones throughout the construction season
    • Provide timely feedback and follow-up
night work lighting
Night Work Lighting
  • Standard Specification for Artificial Lighting
    • To safely and adequately perform the work
    • To make the workers and construction operations visible to traveling public
    • Glare and brightness do not interfere with driver visibility
night work lighting15
Night Work Lighting
  • Working to develop a pilot Special Provision
    • Lighting layout (light placement, mounting height)
    • Glare control
    • Light level and uniformity
    • Aiming of fixtures
work zone traffic management16
Work Zone Traffic Management
  • Work Zone Speed Limit Criteria
    • Reduce 65-mph to 55-mph during lane closures & work operations
    • Reduce 55-mph multi-lane highways to 45-mph if AADT > 10,000, where lanes narrowed, severe lane shifts, work area close to traffic
    • Reduce 55-mph 2-lane rural highways to 45-mph if AADT > 7,000, where lanes narrowed, severe lane shifts, or road surface is degraded
    • Reduce 45-mph multi-lane highways to 35-mph if AADT > 10,000, where severe lane shifts, frequent driveways
    • Reduce 40-mph urban roadways to 30-mph where temporary road, gravel surface, severe lane shifts

Work Zone Traffic Management
  • Revising State Patrol Enforcement Process
    • More flexible deployment agreements
    • Criteria based on traffic volume, lane closures, speed limit, project length, safety history, terrain, traffic composition, night work or traffic stoppages for work operations
