Book Description
During this review process it was determined that research was needed to understand and develop effective countermeasures for wrong-way movements onto freeways and other restricted roads. This research provides TxDOT staff with preventative measures for reducing the frequency and severity of wrong-way entries onto freeway facilities throughout Texas. Researchers performed the following tasks during the project: established state-of-the-practice on safety, design, and operational issues for wrong-way movement on freeways; surveyed state DOTs to get information on typical wrong-way signing and marking and any innovative practices; quantified the frequency, severity, and other important characteristics of wrong-way crashes in Texas based on a review of crash reports and coordination with 911 public safety answering points; identified available countermeasures to reduce wrong-way movements and crashes; evaluated the feasibility and applicability of the available countermeasures to address Texas problems; documented typical situations that were more likely to produce wrong-way entry issues; developed guidelines/recommended practices for application of wrong-way countermeasures and treatments; and developed a checklist for field crews to use for reviewing wrong-way entry issues or suspected problem locations.

Book Description
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.

Book Description
In an increasingly globalised world, despite reductions in costs and time, transportation has become even more important as a facilitator of economic and human interaction; this is reflected in technical advances in transportation systems, increasing interest in how transportation interacts with society and the need to provide novel approaches to understanding its impacts. This has become particularly acute with the impact that Covid-19 has had on transportation across the world, at local, national and international levels. Encyclopedia of Transportation, Seven Volume Set - containing almost 600 articles - brings a cross-cutting and integrated approach to all aspects of transportation from a variety of interdisciplinary fields including engineering, operations research, economics, geography and sociology in order to understand the changes taking place. Emphasising the interaction between these different aspects of research, it offers new solutions to modern-day problems related to transportation. Each of its nine sections is based around familiar themes, but brings together the views of experts from different disciplinary perspectives. Each section is edited by a subject expert who has commissioned articles from a range of authors representing different disciplines, different parts of the world and different social perspectives. The nine sections are structured around the following themes: Transport Modes; Freight Transport and Logistics; Transport Safety and Security; Transport Economics; Traffic Management; Transport Modelling and Data Management; Transport Policy and Planning; Transport Psychology; Sustainability and Health Issues in Transportation. Some articles provide a technical introduction to a topic whilst others provide a bridge between topics or a more future-oriented view of new research areas or challenges. The end result is a reference work that offers researchers and practitioners new approaches, new ways of thinking and novel solutions to problems. All-encompassing and expertly authored, this outstanding reference work will be essential reading for all students and researchers interested in transportation and its global impact in what is a very uncertain world. Provides a forward looking and integrated approach to transportation Updated with future technological impacts, such as self-driving vehicles, cyber-physical systems and big data analytics Includes comprehensive coverage Presents a worldwide approach, including sets of comparative studies and applications
An Evaluation of Low-cost Wrong-way Driving Countermeasures at Partial Cloverleaf Interchanges on Kansas Interstates

Book Description
Wrong-way driving (WWD) incidents and crashes continue to be a serious concern for communities across the United States. Wrong-way drivers have been found to typically travel at high rates of speeds, during low light conditions, and on roadways with limited horizontal maneuverability resulting in reduced reaction times. These variables, along with ones that cannot be quantified are likely the reasons wrong-way crashes result in higher rates of fatalities and serious injuries as compared to other traffic crashes. Previous research on WWD includes statistical analyses of crash data, multiple countermeasure comparisons, investigation of driver characteristics, and proposed rewording of the MUTCD. While research has been conducted on countermeasure effectiveness, research has been varied on the type of interchanges evaluated. This study specifically evaluated low-cost countermeasures at partial cloverleaf interchanges in Kansas. Six ramps were selected in the Topeka, KS metropolitan area, including four study sites and two control sites. Three sets of WWD incident data were gathered over a 10 to 14 day period, one before and two after studies, using two sets of pneumatic road tubes on each ramp. Three cases were established to grade the severity of wrong-way incidents based on wrong-entry, self-correction, and error and the results converted to a rate of incidents per 100,000 entering vehicles (ev). The before study found that incident rates ranged from 3.7 to 92 incidents per 100,000 ev. The countermeasures that were selected for evaluations were red retroreflective delineators, oversized and lowered wrong-way signs, and flashing LED wrong-way sign. The first set of after data were collected immediately after installation of the countermeasures and showed improvements at all but one of the study sites with incident rates ranging from 3 to 103 incidents per 100,000 ev. The second set of after data were collected months after installation and showed more improvement at all of the study sites with incident rates ranging from 0 to 40 incidents per 100,000 ev. The study found that the red retroreflective delineators and the oversized and lowered signs were effective in reducing the number and type for WWD incidents; however, the results for the flashing LED sign were inconclusive. Finally, a study was conducted to evaluate the effectiveness of a WWD incident data collection. Multiple sets of pneumatic road tubes were installed at a partial cloverleaf interchange and it was found the proposed data collection methodology indicated the established WWD incident cases were accurate in their representations of the vehicular movements. The study recommended locations for placement of the two primary counters and the use of a third counter.
