The findings of this research investigation supports the hypothesis that the elderly driver group is disproportionally represented in left turn accidents. Drivers over 70 averaged more left turn accidents per mile than drivers between the ages of 20 to 69. In addition, left turn accidents represent a much larger proportion of total accidents for drivers over 65 than for any other group. A reduction of permissive left turns could aid older drivers. The permissive type of left turn requires the driver to monitor the traffic light and on-coming opposing traffic for a suitable gap. The resulting lengthened information gathering and decision process of older drivers can lead to the increase in left turn accidents.
The two LNCS volume set 9754-9755 constitutes the refereed proceedings of the Second International Conference on Human Aspects of IT for the Aged Population, ITAP 2016, held as part of the 18th International Conference on Human-Computer Interaction, HCII 2016, held in Toronto, ON, Canada, in July 2016, jointly with 14 other thematically conferences. The total of 1287 papers and 186 poster papers presented at the HCII 2016 conferences were carefully reviewed and selected from 4354 submissions. LNCS 9754, Design for Aging (Part I), addresses the following major topics: designing for and with the elderly; technology use and acceptance by older users; psychological and cognitive aspects of interaction and aging; mobile and wearable technologies for the elderly. LNCS 9755, Healthy and Active Aging (Part II), addresses these major topics: smart and assistive environments; aging and social media; aging, learning, training and games; and aging, mobility and driving.
TRB's National Cooperative Highway Research Program (NCHRP) Report 672: Roundabouts: An Informational Guide - Second Edition explores the planning, design, construction, maintenance, and operation of roundabouts. The report also addresses issues that may be useful in helping to explain the trade-offs associated with roundabouts. This report updates the U.S. Federal Highway Administration's Roundabouts: An Informational Guide, based on experience gained in the United States since that guide was published in 2000.
In 1966 the first meeting of the Association for the Study of Attention and Performance was held in the Netherlands to promote the emerging science of cognitive psychology. This volume is based on the most recent conference, held in Israel thirty years later. The focus of the conference was the interaction between theory and application. The organizers chose the specific topic, cognitive regulation of performance, because it is an area where contemporary theories of cognitive processes meet the everyday challenges posed by human interactions with complex systems. Present-day technological systems impose on the operator a variety of supervisory functions, such as input and output monitoring, allocation of cognitive resources, choice of strategies, and regulation of cognitive operations. A challenge for engineers and designers is to accommodate the cognitive requirements called for by these systems. The book is divided into four sections: the presentation and representation of information, cognitive regulation of acquisition and performance, consciousness and behavior, and special populations: aging and neurological disorders.

This one-of-a-kind comprehensive study highlights the importance of automated testing techniques and the significance of vision screening measures other than standard visual acuity testing for assessing all drivers and, in particular, at-risk drivers and older drivers. Non-automated tests tend to be subjective, time-consuming, costly, and heavily reliant on the experience of the examiner. Due to the high collision, injury, and fatality rates of all drivers in the State of Arizona, and the disproportionate number of at-fault older drivers and collision risks in the States of Arizona and Florida, new and automated screening methodologies and vision standards are now needed to promote road safety, predict visual impairment, and evaluate possible restriction or confiscation of driver's licenses. This study demonstrates that environmental factors and manner of collisions increase in collision involvement for drivers between ages 50 to 59 years in both Arizona and Florida. Drivers age 80 to 89 years in both states are most likely at-fault in collisions compared to all other age cohorts. These results are consistent among drivers cited for collision involvement due to visual defects. These findings, which span an 11-year period from 1991 to 2001, not only apply to Arizona and Florida, two states with some of the largest proportions of older individuals in the United States, but, as a global survey of motor vehicle bureau directors or their representatives in the United States, Commonwealth of Puerto Rico, United Kingdom, Canada, New Zealand, and Australia illustrate, any state, country, province, territory, commonwealth, or nation with an increasing number of older drivers. A pilot study, to follow, ultimately allows for the implementation of effective strategies for screening of visual impairment and eye disease in all Arizona drivers. Snellen acuity, the most widely used vision testing measure, accounts for less than 0.1% of the visual field and fails to quantify contrast sensitivity and color vision (Fink and Sadun, 2004), two of several visual parameters needed for safe driving. It is recommended that at-risk and older drivers in Arizona be tested for vision through a newly designed system of measures provided by two automated tests (to test vision condition and function) and one driving simulator (to assess eye status). Hence, it is integrated into a larger system and additional recommendations are provided as these relate to motor vehicle operation skills and cognition. These automated systems and methodologies may ultimately serve as a prototype of transportation license testing improvements for all other states, countries, and agencies (e.g., aviation, rail, maritime, commercial vehicles, etc.) to follow. Such techniques may also reduce the incidence of fraudulent schemes and issuances of driver's licenses, commercial driver's licenses, and hazardous materials transportation licenses.
Human error is involved in more than 90 percent of traffic accidents, and of those accidents, most are associated with visual distractions, or looking-but-failing-to-see errors. Human Factors of Visual and Cognitive Performance in Driving gathers knowledge from a human factors psychology standpoint and provides deeper insight into traffic -user beh

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.
