This book was released on 2013 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the efforts and results of a number of studies and evaluations performed by TTI researchers to evaluate the effect and value of steady-burn warning lights on temporary traffic control devices used to delineate the correct travel path in work zones. The effort also included a study of steady-burn warning lights on temporary barrier walls relative to the potential use of delineators currently used on permanent barrier wall. The research includes an assessment of the potential incremental increase in luminance (and benefit of that increase to drivers) during vulnerable driving conditions. These conditions include periods of heavy fog, periods when dew has formed on the reflective sheeting on channelizing devices, periods when dirt and grime have accumulated on the channelizing device, and when channelizing devices are viewed by drivers of large trucks who have a larger observation angle between their eye and the vehicle headlights that are illuminating the reflective sheeting. The researchers assessed the effect of warning light misalignment upon its apparent luminance to drivers, as well as the effect of providing steady-burn warning lights on channelizing devices and temporary barrier walls upon driver visual glance behavior, driving behavior, and driver opinions. Finally, the researchers performed an assessment of the costs of providing steady-burn warning lights and the necessary improvements in work zone safety that would need to be achieved in order to offset those costs. Based on the findings, the researchers recommended that the statewide application of steady-burn warning lights in all work zones be discontinued.

Available in PDF, EPUB and Kindle. Book excerpt: This report documents the results of a study to evaluate the safety and mobility impacts associated with the elimination of steady burn warning lights on drums in construction work zones. National crash data are compared among states with different policies regarding the use of steady burn warning lights and an in-depth investigation of Michigan work zone crashes is also conducted. The results of the crash data investigation are supplemented by a series of field studies that examine driver behavior in work zones, both with and without steady burn warning lights. Additional field studies are conducted to assess the luminance characteristics of drums with and without lights, as well as the condition of drums in each type of work zone. The luminance studies are supplemented by additional studies that are conducted in a controlled environment.

This book was released on 2006 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The project focuses on two major issues - the improvement of current work zone design practices and an analysis of vehicle interarrival time (IAT) and speed distributions for the development of a digital computer simulation model for queues and travel delays in work zones. Important considerations in the development of work zone design guidelines include guidance, delineation, and the safety of workers and drivers. A nationwide survey of current work zone best practices was conducted. Based on the review of the existing ODOT guidelines, superior practices available in other states, relevant research, and professional judgment of personnel involved in work zone activities, a set of guidelines for work zone design are proposed. It is anticipated that these research findings will result in the better design of work zones which will minimize traffic delays and improve safety. In the second part of the project trailers, each using two Wavetronix microwave radar units in side-fire mode, were developed to nonintrusively measure traffic. The traffic was measured at six work zones sites with different types of lane configurations at different freeways in Ohio. Traffic on the road was also independently measured using video and radar, and the results compared to records from the trailers to verify that the trailers were measuring the traffic with reasonable accuracy. IAT data of successive vehicles in freeflowing traffic ahead of work zones were analyzed and IAT distributions were generated as a function of the traffic volume for each lane and relationships between traffic volumes and cumulative IAT distributions were established allowing a direct conversion from hourly traffic counts to corresponding cumulative IAT distributions. This conversion method produces fairly accurate cumulative IAT distributions for selected hourly traffic volumes. It was also found that the same cumulative IAT distribution can be used to model the free-flowing traffic at other freeway locations in Ohio, which means that the IAT distributions are portable and scalable and a microscopic digital computer simulation model based on queueing theory may be developed to investigate traffic delays in work zones.
