Available in PDF, EPUB and Kindle. Book excerpt: Full-scale vehicle crash tests evaluated performance of typical work zone traffic control devices. Modified test procedures and evaluation criteria from NCHRP Report 230 were used in 108 tests, providing significant insight into impact performance. Plastic drums used as channelizing devices, cones, tubes, and vertical panels performed well in most tests, presenting no hazards in terms of passenger compartment intrusion, interference with vehicle control, or threat to workers and other traffic from impact debris.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.
