• Abstract:
  This report discusses the usefulness of creating a work zone traffic safety culture as a methodology to improve the overall
  
  safety of both work zone personnel and the traveling public in Missouri. As part of this research, the existing MoDOT
  
  Work Zone Rating Survey was analyzed and augmented to collect public perception of work zone safety, historical data
  
  on work zone crashes were evaluated to identify trends that are particular to, and attributes that are associated with
  
  severe crashes were identified.
  
  Results from the existing Work Zone Rating survey show a difference in stakeholder perceptions regarding the adequacy
  
  of work zone warning signs and the safety level in traveling through work zones. Based on survey responses from current
  
  MoDOT employees, existing work zone warning signage and guidance (barrels, cones, and striping) are adequate to
  
  protect the driving public and are in accordance with the MoDOT Temporary Traffic Control Elements. However,
  
  responses from the general public reveal that a plurality of respondents perceived that the warning signs were
  
  insufficient in terms of information provided, provided inaccurate information, or were wrongly placed.
  
  An evaluation of crash data shows that there is not an elevated risk in work zones when compared to non-work zones.
  
  Fatal and severe crashes occur more frequently when roadway conditions were dark or involved multiple vehicle
  
  interactions. Contributing circumstances in work zone crashes involving vehicle interactions suggest that human factors
  
  are key risk elements. Solutions to mitigate fatal or severe crashes should include stakeholder education, higher
  
  enforcement and legislation designed to minimize distracted driving, and engineering solutions designed to increase
  
  driver awareness.
