NCHRP Project 17-61 62 SUMMARY AND RESEARCH RECOMMENDATIONS Summary In this report, researchers have documented the results of multiple analyses focused on developing an improved understanding of work zone crash characteristics and countermeasure effectiveness. In-depth analyses of work zone crash narratives and other data sources above and beyond standard fields and codes in state and national crash databases yielded several useful insights into work zone factors associated with common types of crashes.

NCHRP Project 17-61 63 crash narratives, as was the presence of certain temporary traffic control devices. In one instance, type 3 barricades placed in the opposing left-turn lane at a signalized intersection limited the ability leftturning traffic coming from the other direction to see approaching through lane traffic during the permissive green phase.

NCHRP Project 17-61 64 It is recommended that the adequacy of existing training for work zone traffic control relative to arterials and intersections be examined, and improvements to that training be made where appropriate. Several of the crashes examined in detail under this study pointed to driver confusion and visibility issues when work zones were performed in the vicinity of intersections.
