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.

Book Synopsis Light Use Study for Vertical Channelization Devices by : David P. Sabers
Download or read book Light Use Study for Vertical Channelization Devices written by David P. Sabers and published by . This book was released on 2003 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the Manual of Uniform Traffic Control Devices (MUTCD) does not require the use of warning lights on channelization devices, the Arizona Department of Transportation (ADOT) has historically required their use on all traffic control devices used at nighttime construction zones. This report documents research done for ADOT on the use of steady-burn warning lights on vertical panels in roadway construction zones. Specific tasks included a review of the requirements and policies of the departments of transportation of other states regarding the use of flashing warning lights on traffic control devices, a review of ADOT's construction zone requirements, a search for relevant research, reviews of construction zone accident reports and incident logs, and interviews with ADOT field construction staff regarding the past performance of the Ultra Panels (Type III sheeting) with and without steady-burn warning lights.
Book Synopsis Evaluation of Warning Lights on Maintenance of Traffic Devices and Development of Possible Alternatives by : LuAnn Theiss

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.

Book Synopsis Work Zone Traffic Control Delineation for Channelization by : Kenneth S. Opiela
Download or read book Work Zone Traffic Control Delineation for Channelization written by Kenneth S. Opiela and published by . This book was released on 1990 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a study of the delineation requirements for work zone traffic control. The research included a comprehensive review of past studies and current practices, and an examination of current standards. It was concluded that, in spite of the increasing number of different types of channelizing devices, there appears to be no scientific basis for the spacing criteria for the use of devices for channelization purposes in the taper or tangent sections of a work zone. A laboratory-based testing procedure was used to determine the most appropriate spacing configuration. An interactive video system was used to test subject recognition distances of eight different device types spaced at the standard distance, 1.5 times and 2.0 times the standard distance. Over 240 subjects were tested.

Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Download or read book Roadside Design Guide written by American Association of State Highway and Transportation Officials. Task Force for Roadside Safety and published by AASHTO. This book was released on 2011 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Roadside Design Guide presents a synthesis of current information and operating practices related to roadside safety and is written in dual units-metric and U.S. Customary. This book is a guide. It is not a standard, nor is it a design policy. It is intended to use as a resource document from which individual highway agencies can develop standards and policies. Although much of the material in the guide can be considered universal in its application, several recommendations are subjective in nature and may need modification to fit local conditions. However, it is important that significant deviations from the guide be based on operational experience and objective analysis. The 2011 edition of the AASHTO Roadside Design Guide has been updated to include hardware that has met the evaluation criteria contained in the National Cooperative Highway Research Program (NCHRP) Report 350: Recommended Procedures for the Safety Performance Evaluation of Highway Features and begins to detail the most current evaluation criteria contained under the Manual for Assessing Safety Hardware, 2009 (MASH). For the most part, roadside hardware tested and accepted under older guidelines that are no longer applicable has not been excluded in this edition." -- AASHTO website.
Book Synopsis Evaluation of Diamond Pattern for Use on Work Zone Barricade Rails by : Donald A. Gordon
Download or read book Evaluation of Diamond Pattern for Use on Work Zone Barricade Rails written by Donald A. Gordon and published by . This book was released on 1982 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A controlled field study was conducted to evaluate recently developed work zone channelization panels. Two designs were considered: the first showed an orange diamond on a white background; the other a white diamond on an orange field. Test subjects viewed the orange and the white diamond panel designs and made judgements concerning the legibility, effectiveness and acceptability of the panels. Twenty test subjects viewed the panels during the day, and twenty observed at night. The orange diamond design was more legible than the white diamond design under both day and night viewing conditions. It was also preferred to the white diamond design.
