Available in PDF, EPUB and Kindle. Book excerpt: In this report, researchers present an assessment framework for evaluating the expected crash consequences of performing a particular work activity on a given highway at night versus doing that same activity during the day. Researchers predicate the framework on the availability of normal crash rates (crashes per 100 million-vehicle-miles), differentiated by daytime and nighttime conditions, on the particular roadway segment of interest. These normal rates are then adjusted on a percentage basis to account for the incremental increase in crashes expected under both the daytime and nighttime work conditions. An analyst would multiply the adjusted crash rates, representing the additional crash risk due to work activities, by traffic volumes expected to encounter the work zone in either the daytime or the nighttime period and the length of the work zone to determine the number of additional crashes that would be expected to occur due to the work zone in either period. Also included in this report is a review of several potential countermeasures identified by the research team to reduce crashes resulting from active night work zone. Researchers provide a critique of each one with regard to potential adoption consideration by the Texas Department of Transportation. Overall, researchers could not justify widespread or blanket adoption of any of the countermeasures.

Available in PDF, EPUB and Kindle. Book excerpt: In this report, Texas Transportation Institute researchers identify key work zone safety and mobility performance measures that the Texas Department of Transportation (TxDOT) should target as part of a work zone monitoring program within a district, region, or across the state. Analysis methodologies and computational procedures are presented that will yield the recommended performance measures. For mobility-based measures, researchers recommend that TxDOT target the collection of queue length and travel time delay data caused by temporary lane closures, as the congestion and delays that result from those activities are the simplest to isolate and attribute to the work activities themselves. With regard to work zone safety monitoring, researchers developed procedures that aid a district or project engineer in determining which projects are most suitable for safety monitoring via a periodic review of crash statistics occurring before and during the project. Researchers developed graphs that indicate combinations of work zone length (or work zone segment length), average daily traffic, normal crash rate, and work zone phase or project direction that will most likely allow for reasonable inferences to be made regarding the relative level of safety being maintained within the project. Researchers also developed graphs to aid field or district personnel in quickly determining whether accident frequencies being experienced during a project are within, or above, tolerance limits for that type of project on that facility.

Available in PDF, EPUB and Kindle. Book excerpt: This implementation guide describes the conceptual framework, data requirements, and computational procedures for determining the safety and mobility impacts of work zones in Texas. Researchers designed the framework and procedures to assist district-level personnel who have responsibility for work zone safety and mobility impact reviews of significant projects as required by Texas Department of Transportation (TxDOT) policy. In this guide, researchers describe the types of impact monitoring and analysis that can occur as part of ongoing project activities and those that can be performed during post-project reviews. Analysis procedures are presented to assist in determining which projects should be targeted for regular reviews of crash data during the project, as well as the increase in crash frequency that is indicative of unusual safety concerns that should be investigated further through field observations. Researchers also present analysis procedures to guide district personnel in determining the queue lengths, individual vehicle delays, and total vehicle-hours of delay that are created during temporary lane closures in a project.

Available in PDF, EPUB and Kindle. Book excerpt: "TRB's National Cooperative Highway Research Program (NCHRP) Report 726: A Guidebook for Nighttime Construction: Impacts on Safety, Quality, and Productivity provides suggested guidance on the conduct of nighttime highway construction and maintenance operations. These guidelines are based on best practices and strategies for nighttime operations that relate to the personnel and traveling public safety and the quality of the as-built facility. The guide also addresses work-zone risk analysis planning and implementation, construction nuisances to both neighbors and workers, and work-zone illumination methods."--Publisher's description.

Available in PDF, EPUB and Kindle. Book excerpt: Through a literature review and discussions with highway and transportation officials in several states, information was obtained on questions and concerns relating to the planning, safety, and traffic control aspects of night maintenance and construction activities and their advantages and disadvantages. The information obtained was used to develop general guidelines on when and how maintenance and construction work should be performed at night. The report presents case studies illustrating the activities required in different types of night maintenance and construction activities. Although there are many potential disadvantages of working at night, it is believed that through the experience that has been gained and proper planning and special concern for workmen and motorist safety, the night alternative is feasible for selected work.
