Book Description
Researchers at Texas A & M Transportation Institute completed a study of E-Modified, Enhanced E-Modified, and Clearview 5W for overhead and shoulder-mounted guide signs. The overhead guide signs consisted of three 6-letter, 16-inch tall font words stacked over each other at a standard spacing. The test word was on the middle line and had a leading uppercase letter followed by a combination of lowercase ascender and neutral letters, lowercase descender and neutral letters, or all lowercase neutral letters. The word on the top line was "Paying," and the word on the lower line was "Likely." These words were chosen such that the descender and ascender letters encroached on the test words to evaluate the impact of interline spacing. The shoulder-mounted signs consisted of two-digit numbers. Both the word and number legends were chosen to have similar footprints to minimize the likelihood of guessing based on recognition rather than legibility. Legibility distance data were recorded for each word read; however, the researchers completed the analysis based on the legibility index (LI), which is the legibility distance divided by the legend height. A detailed table of previous research is provided in LI values for cross comparison. Similar to previous research, there were mean LI values in some instances for Enhanced E-Modified and Clearview 5W that were larger than E-Modified; however, none of them were statistically significant. The only statistically significant differences reported were with respect to subject age (e.g., 18-35, and 65+) and day versus night, and at night within Clearview 5W with respect to legend type. The mean LI were 68.9 and 45.2 for 18-35 versus 65+ participants in the daytime condition, respectively, and 50.2 and 36.4 for 18-35 versus 65+ participants in the nighttime condition, respectively. It was shown that the cost to implement Clearview 5W would be more expensive than E-Modified, so it was recommended that future research focus on evaluating Clearview 5WR.

Book Description
"Recommended."--CHOICE: Current Reviews for Academic Libraries "Coughlin and DíAmbrosioís edited volume is a welcome contribution to highlighting this issue for gerontologists. The collection is an informative and useful reference for students, researchers, practitioners, planners, and policy analysts"--The Gerontologist This solution-focused volume fills a gap in the literature by addressing the key issues around mobility and transportation for the aging Baby Boomer generation--issues that will be significantly different than those of previous generations of older adults. This new generation, many of whom will continue to work past the traditional retirement age and expect to pursue an active lifestyle, may have to confront new transportation technology, the need to use public transportation, and ways to continue driving safely as their eyesight fades and reaction time slows down. This volume examines many of the issues faced by policymakers, transportation officials, vehicle manufacturers, health and human services professionals, and aging adults themselves as the largest generation prepares to enter late adulthood. The volume's editors are both at the MIT AgeLab, whose multi-disciplinary team designs, develops and deploys innovations to enhance quality of life for aging populations. Through the contributions of a diverse group of theorists and practitioners, including recommendations from the National Older Driver Safety Advisory Council, a collaboration between AARP's Driver Safety Program and the MIT AgeLab, the book discusses several key topics pertinent to Aging America and transportation. Among them are the changing demographics of the population, how this generation's lifestyle choices affect mobility, technology trends in private vehicles, changes in the infrastructure and transportation system, the "new" older driver, and issues of safety and education among older drivers. This book also explores practical solutions and strategies, such as new transportation options and innovations that will significantly impact the future of mobility for older adults, for keeping these seniors active and mobile well into their later years. Key Features: Focuses on the unique mobility needs of the aging Baby Boomer generation Provides practical solutions and strategies for policy changes to enhance the mobility of older adults Examines issues faced by policymakers, transportation officials, vehicle manufacturers, health and human services professionals, and aging adults Discusses strategies for updating the infrastructure and transportation system, driving safety education for older drivers, and trends in private vehicle innovations

Book Description
This comprehensive 2nd edition covers the key issues that relate human behavior to traffic safety. In particular it covers the increasing roles that pedestrians and cyclists have in the traffic system; the role of infotainment in driver distraction; and the increasing role of driver assistance systems in changing the driver-vehicle interaction.

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
Expectancy relates to a driver's readiness to respond to situations, events, and information in predictable and successful ways. This report describes the concept of driver expectancy in the context of the driving task, and provides examples of expectancy and expectancy violations. It includes a procedure for identifying general and specific expectancy violations to enable engineers to develop remedial treatments to deal with expectancy problems.
