Work zones tend to cause hazardous conditions for drivers and construction workers since they generate conflicts between construction activities and traffic. A clear understanding of the characteristics of work zone crashes will enhance the selection of the appropriate measures that can minimize the negative impacts of work zones. This study investigated the characteristics of work zone crashes that occurred in Virginia between 1996 and 1999. The information on each crash was obtained from the police crash record. The location of each crash was categorized as being in one of the five areas of a typical work zone: advance warning area, transition area, longitudinal buffer area, activity area, and termination area. An analysis of the percentage distributions was then carried out with respect to area in work zone, severity, type of collision, and type of highway. The proportionality test was used to determine significant differences at the 5 percent significance level. Selected crash characteristics, such as the proportions of single- and multi-vehicle crashes, were compared for work zone and non-work zone crashes. The results indicated that the activity area was the predominant location for work zone crashes regardless of highway type and that rear-end crashes were the predominant type of crash. The results also indicated that the proportion of sideswipe same direction crashes in the transition area was significantly higher than in the advance warning area and that work zone crashes involved a higher proportion of multi-vehicle crashes and fatal crashes than did non-work zone crashes.

This reference work was compiled as a resource for those needing assistance in locating Texas criminal justice statistics. R. Scott Harnsberger has compiled more than 600 entries describing statistical sources for Texas crime; criminals; law enforcement; courts and sentencing; adult and juvenile corrections; capital punishment and death row; victims of crime; driving/boating under the influence; traffic fatalities; substance abuse and treatment; polls and rankings; and fiscal topics such as appropriations, revenues, expenditures, and federal aid. The sources for these statistics originate primarily, but not exclusively, from federal and State of Texas agencies, boards, bureaus, commissions, and departments. The following types of publications are included: annual, biennial, and biannual reports; reports issued in series; analytic and research reports; statistical compilations; budgets and other fiscal documents; audits, inspections, and investigations; census publications; polls; projections; rankings; surveys; continuously updated online resources; and datasets. Harnsberger has annotated the entries to provide sufficient detail to enable users to decide whether the listed resources merit further investigation. Additional notes contain URLs and information regarding the scope of the published data; title changes; related publications; and the availability of earlier data, previous editions, online tables, and datasets. This book will prove to be a valuable resource for students, faculty, researchers, government officials, and individuals in the law enforcement, correctional, and judicial professions.

"The safe and efficient flow of traffic through work zones must be established by improving work zone conditions. Therefore, identifying the factors associated with the severity and the frequency of work zone crashes is important. According to current statistics from the Federal Highway Administration, 2,372 fatalities were associated with motor vehicle traffic crashes in work zones in the United States during the four years from 2010 to 2013. From 2002 to 2014, an average of 1,612 work zone crashes occurred in Kansas each year, making it a serious concern in Kansas. The objectives of this study were to analyze work zone crash characteristics, identify the factors associated with crash severity and frequency, and to identify recommendations to improve work zone safety. Work zone crashes in Kansas from 2010 to 2013 were used to develop crash severity models. Ordered probit regression was used to model the crash severities for daytime, nighttime, multi-vehicle and single-vehicle work zone crashes and for work zones crashes in general. Based on severity models, drivers from 26 to 65 years of age were associated with high crash severities during daytime work zone crashes and driver age was not found significant in nighttime work zone crashes. The use of safety equipment was related to reduced crash severities regardless of the time of the crash. Negative binomial regression was used to model the work zone crash frequency using work zones functioned in Kansas in 2013 and 2014. According to results, increased average daily traffic (AADT) was related to higher number of work zone crashes and work zones in operation at nighttime were related to a reduced number of work zone crashes. Findings of this study were used to provide general countermeasure ideas for improving safety of work zones" (page ii).

Rural two-lane highways constitute a large percentage of the highway system in Kansas. Preserving, expending, and enhancing these highways require the set-up of a large number of one-lane, two-way work zones where traffic safety has been a severe concern. Aimed at reducing the work zone crashes attributable to inattentive driving, the Kansas Department of Transportation (KDOT) initiated a research project to evaluate the effectiveness of a traffic warning sign that is assembled by using the emergency warning flashers of the vehicles in one-lane, two-way work zones. This warning sign was named as the Emergency Flasher Traffic Control Device (EFTCD). It works in the following fashion. When a vehicle entering a one-lane, two-way work zone where stopping is required for waiting to pass the work zone, the driver is required to turn on its emergency warning flashers to warn the following vehicles of the work zone stopping condition. The EFTCD is flexible and cost-effective and may particularly benefit those work zones that are frequently moved due to the construction progress. To accurately evaluate the effectiveness of the proposed EFTCD, researchers conducted experiments in three one-lane, two-way work zones in Kansas including two with a 55-mph speed limit and one with a 65-mph speed limit. During experimental period, researchers collected vehicle speed data with and without the EFTCD and surveyed drivers for their interpretation of this warning sign and recommendation on its potential implementation. Analyses results showed that the EFTCD effectively reduced the mean speeds in work zones as well as the proportions of notably high speeds. In addition, survey results indicated that the EFTCD successfully captured the attention of most drivers when they approached the work zones. A majority of drivers recommended the implementation of this warning sign in the work zones. Therefore, researchers concluded that the EFTCD was effective in one-lane, two-way work zones. Recommendations on future research were also presented based on the results of this study. The outcomes of this research project benefit not only Kansas, but also other States where rural two-lane highways constitute a high percentage of their highway systems.
