• 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.
