“…Multivehicle collisions were consistently overrepresented in work zones (13-15, 20, 22, 23). This overrepresentation was also significant for large-truck-involved collisions in work zone crashes (14,16,19). Moreover, large-truck-involved collisions in work zones were more severe than non-truck-involved collisions (19,24), similar to non-work zone situations.…”

“…The limited research available has analyzed the distribution and characteristics of injury and non-injury work zone crashes, and the results appear inconsistent. On the one hand, there is evidence that work zone crashes are slightly less severe than non-work zone crashes (12,13,(16)(17)(18). For instance, Rouphail et al (13) reported a 20% decrease in fatal-and injury-crash proportions.…”

Society pays a high cost for work zone crashes in terms of operational disruptions, property damage, injuries, and loss of life. Given narrow lanes in work zones, large trucks are of particular concern. Truck-involved collisions in work zones, as opposed to non-truck-involved collisions in North Carolina, are empirically examined. This examination helps in understanding which work zone attributes are empirically associated with the most seriously injured occupant and total harm in a crash. Specifically, with a unique data set, effects of the following variables were explored: type of work zone, presence of warning signs and cones, type of activity in the work zone, location of the crash in the work zone, and construction impact of the work zone on the roadway. The results show that work zone crashes in North Carolina, especially those involving large trucks, were more injurious than were non—work zone crashes. Rigorous modeling results suggest that truck-involved multivehicle crashes were most injurious and harmful when ( a) they occurred on two-way undivided or two-way divided but unprotected (without a median barrier) roadways; ( b) the roadway was closed and a detour was required on the opposite side; ( c) they occurred adjacent to the work area; and ( d) the posted speed limits were higher. The results provide valuable information on high-risk factors in work zones.

“…Three studies showed that work-zone crashes were more severe than other crashes (9,11,12), whereas two other studies concluded that the severity of work-zone crashes did not significantly differ from all crashes (2,6 ). Five studies stated that work-zone crashes were slightly less severe than all crashes (5,7,8,10,13).…”

Work zones tend to cause hazardous conditions for drivers and construction workers, because they create conflicts between construction activities and traffic, thus exacerbating the existing traffic conditions. Every effort should therefore be made to minimize the negative impacts of work zones. A clear understanding of work-zone crash characteristics will help to determine appropriate measures to minimize work-zone hazards. This study investigated the characteristics of work-zone crashes that occurred in Virginia from 1996 through 1999. The information on each crash was obtained from police crash records. Each crash was located in one of five areas of the work zone—( a) advance warning, ( b) transition, ( c) longitudinal buffer, ( d) activity, and ( e) termination. The percentage distributions were analyzed relative to crash location, crash severity, collision type, and highway type. The proportionality test was used to determine significant differences at the 5% significance level. The results indicate that the activity area is the predominant location of work-zone crashes regardless of highway type, and rear-end crashes are the predominant crash type. The results also indicate that the proportion of sideswipe-in-same-direction crashes in the transition area is significantly higher than that in the advance warning area.

Identifying risk factors for road traffic injuries can be considered one of the main priorities of transportation agencies. More than 12,000 fatal work zone crashes were reported between 2000 and 2013. Despite recent efforts to improve work zone safety, the frequency and severity of work zone crashes are still a big concern for transportation agencies. Although many studies have been conducted on different work zone safety-related issues, there is a lack of studies that investigate the effect of adverse weather conditions on work zone crash severity. This paper utilizes probit-classification tree, a relatively recent and promising combination of machine learning technique and conventional parametric model, to identify factors affecting work zone crash severity in adverse weather conditions using 8 years of work zone weatherrelated crashes (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013) in Washington State. The key strength of this technique lies in its capability to alleviate the shortcomings of both parametric and nonparametric models. The results showed that both presence of traffic control device and lighting conditions are significant interacting variables in the developed complementary crash severity model for work zone weather-related crashes. Therefore, transportation agencies and contractors need to invest more in lighting equipment and better traffic control strategies at work zones, specifically during adverse weather conditions.
