TRB¿s National Cooperative Highway Research Program (NCHRP) Report 627: Traffic Safety Evaluation of Nighttime and Daytime Work Zones explores the crash rates for nighttime and daytime work zones and examines management practices that promote safety and mobility in work zones. The report also highlights work-zone crash reporting suggestions designed to help improve the data collected on work zone crashes.

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.

Get a complete look into modern traffic engineering solutions Traffic Engineering Handbook, Seventh Edition is a newly revised text that builds upon the reputation as the go-to source of essential traffic engineering solutions that this book has maintained for the past 70 years. The updated content reflects changes in key industry standards, and shines a spotlight on the needs of all users, the design of context-sensitive roadways, and the development of more sustainable transportation solutions. Additionally, this resource features a new organizational structure that promotes a more functionally-driven, multimodal approach to planning, designing, and implementing transportation solutions. A branch of civil engineering, traffic engineering concerns the safe and efficient movement of people and goods along roadways. Traffic flow, road geometry, sidewalks, crosswalks, cycle facilities, shared lane markings, traffic signs, traffic lights, and more—all of these elements must be considered when designing public and private sector transportation solutions. Explore the fundamental concepts of traffic engineering as they relate to operation, design, and management Access updated content that reflects changes in key industry-leading resources, such as the Highway Capacity Manual (HCM), Manual on Uniform Traffic Control Devices (MUTCD), AASSHTO Policy on Geometric Design, Highway Safety Manual (HSM), and Americans with Disabilities Act Understand the current state of the traffic engineering field Leverage revised information that homes in on the key topics most relevant to traffic engineering in today's world, such as context-sensitive roadways and sustainable transportation solutions Traffic Engineering Handbook, Seventh Edition is an essential text for public and private sector transportation practitioners, transportation decision makers, public officials, and even upper-level undergraduate and graduate students who are studying transportation engineering.

"The Highway Safety Manual (HSM) is a resource that provides safety knowledge and tools in a useful form to facilitate improved decision making based on safety performance. The focus of the HSM is to provide quantitative information for decision making. The HSM assembles currently available information and methodologies on measuring, estimating and evaluating roadways in terms of crash frequency (number of crashes per year) and crash severity (level of injuries due to crashes). The HSM presents tools and methodologies for consideration of 'safety' across the range of highway activities: planning, programming, project development, construction, operations, and maintenance. The purpose of this is to convey present knowledge regarding highway safety information for use by a broad array of transportation professionals"--p. xxiii, vol. 1.

"TRB Special Report 292 ... recommends the creation of an independent scientific advisory committee (SAC). The SAC would be charged with development of a transparent process for identifying and prioritizing research needs and opportunities in highway safety, with emphasis on infrastructure and operations, and using the process developed to recommend a national research agenda focused on highway infrastructure and operations safety. The report also explores opportunities to improve the quality of highway safety research." -- publisher's website.
