• Abstract:
  This report presents research performed analyzing crashes in work zones in the state of New Jersey so as to ; identify critical areas in work zones susceptible to crashes and key factors that contribute to these crashes. A field ; data collection on New Jersey roadways was performed for a select number of work zones to provide a better ; understanding of driver behavior in New Jersey work zones. The research also sought to identify where data ; needs are limited in evaluating work zone crashes in New Jersey and make recommendations on how the gaps in ; these needs can be addressed. Innovative strategies that hold potential for reducing work zone crashes were also ; identified. ; Crash frequency and crash severity models were developed to identify factors that contribute to number and ; severity of crashes in work zones. Negative binomial models were used to estimate: total number of crashes; ; frequency of injury crashes; and frequency of property damage only crashes. Binary logistic regression models ; were used to estimate severity for crashes where the driver is at fault, for drivers and for occupants in crashes at ; work zones. Recommendations on the operation and design of the work zone to reduce crash frequency and ; severity are presented based on the findings of the study.
