This book was released on 1996 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Highway Facilities for an Aging Arizona Population written by Sharon Baggett and published by . This book was released on 2003 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research project is threefold: to examine the current knowledge of state-of-the-art highway design practices aimed at increasing the safety of older drivers; to assess the crash and fatality data for older drivers in Arizona; and to survey older adults regarding their perceptions of Arizona's roadways and possible needs for enhancement. Older adults increasingly make up a larger part of the driving population. Age related declines and complications from medical conditions put older drivers at higher risk of collision, and when in collision, of a fatal injury. It is recommended that Arizona use locations identified in this study as having high rates of collisions involving older adults to develop test sites for roadway improvements. It is also recommended that the state begin to review its screening, assessment and education for older drivers with the intent of developing a more stringent screening and assessment process and develop and implement self-testing for older adults to support improved driving safety.

Book Synopsis Pedestrian Accidents in Arizona by : Judson S. Matthias
Download or read book Pedestrian Accidents in Arizona written by Judson S. Matthias and published by . This book was released on 1985 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research investigated the causes of pedestrian accidents in Arizona to discover why Arizona's pedestrian accident rate is higher than the national average. All pedestrian accidents for 1981, 1982, and 1983 that were computerized in the state accident report system were examined. All acccidents (37,784) that could be located *2.6% could not be located) were plotted by location and reported cause. Accident rates for urban areas were higher than for rural areas. The only identified pattern was that urban accidents and fatalities tend to occur on wide, high speed arterial streets. Causes of approximately 50% of all accidents were failure to yield by motorist or pedestrian and not using a crosswalk. It was concluded that there are no engineering countermeasures that would be useful. Education of the public, particularly children under 14 years of age seems to be the only useful countermeasure. Arizona is heavily urbanized with very little rural population to offset the larger than average rate. The Indian reservations are similar to the rural counties and do not contribute to the high rate, although the rate of Indian reservations is higher than that of rural counties. Volume I contains the text and summary figures relevant to the discussion of the results of the research. Volume II, 113 pages, contains the appendices.
Book Synopsis Attention and Performance XVII by : Daniel Gopher
Download or read book Attention and Performance XVII written by Daniel Gopher and published by MIT Press. This book was released on 1999 with total page 842 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Motor vehicles are the primary source of transportation in the United States. While this is true for any age group, the older population tend to rely more heavily on automobiles because of easy access and availability, compared to public transportation even when it is available. Older drivers aged 65 years and older are more vulnerable to fatal crashes due to cognitive impairments and frailty. When older drivers are involved in crashes, they sustain higher injury severities compared to younger drivers. One location where older driver experience higher crash risk is intersection, due to the complexity of the situation involving multiple tasks and movements. The objectives of this study were to determine risk factors associated with intersection-related crashes involving older drivers in the Midwestern states and to provide countermeasure ideas to improve safety. Five-year fatal crash data from 2014 to 2018 from the Fatality Analysis Reporting System (FARS) database were utilized, and statistical analysis was carried out to identify characteristics of fatal crashes involving older drivers and risk factors associated with intersection crashes among this age group. Three separate binary logistic regression models were developed to identify statistically significant predictor variables. First model represents older drivers who are involved in fatal single-vehicle crashes. Second model represents fatal multi-vehicle crashes involving at least one older driver, whereas the third model represents fatal single-vehicle crashes involving drivers younger than 65 years for comparison purposes. The dependent variable is whether a fatal crash occurs at an intersection location or not. Many independent variables that include various crash, driver, vehicle, and environmental factors were considered. By considering a 95 percent confidence level, odds ratios were estimated and used to identify relative risk factors of fatal intersection crashes. Analysis showed that controlled intersections, two-way undivided highways, and roads with posted speed limits less than 55 mph increased the risk of fatal single-vehicle and multi-vehicle crashes for older drivers. Fatal single-vehicle crashes were especially prevalent for these drivers. Factors such as urban roadways, driver age older than 75 years, nighttime driving, and speeding increased the risk of single-vehicle fatal intersection crashes, while turning movements and intersecting paths, straight and level roadways, two-lanes highway, and violation of roadway rules increased the risk of multi-vehicle fatal intersection crashes for older drivers. Single-vehicle fatal intersection crash analysis also showed that controlled intersections, two-way undivided highways, roads with posted speed limits less than 55 mph, urban roadways, speeding, nighttime driving, and fixed objects increased the risk of intersection-related fatal single-vehicle crashes, especially for older drivers. However, factors such as straight and level roadways, impaired driving, driver obesity, and the operation of recreation vehicles, buses, or motorcycles increased the risk of single-vehicle fatal intersection crashes for drivers in other age categories. Based on model results, countermeasure ideas to improve the safety of older drivers at intersections as well as other road users were identified. Among suggested ideas, improving intersections designs to accommodate older driver needs is recommended, such as implementing roundabouts when it is appropriate, reach minimum of 75-degree skew angel at intersection, providing protected left turn signals, flashing yellow arrow, restricted crossing U-turn, median U-turn, using rumble stripes along the side of roadway and median, providing transverse rumble strips (TRS) at intersections, improving roadway lighting, signs and markings at intersections and interchanges, implementing roadway diet, enhancing roadway signs and retroreflective delineation, providing cable, guardrail, or concrete barriers, implementing continuous raised-curb medians, enhancing lane drop marking on interchanges, providing acceleration and deceleration lane for merging and diverging locations, providing fixed or portable changeable message signs, enhancing high friction surface treatments on risk prone locations, increasing contrast markings on concrete pavement. Beside the engineering countermeasures, using newer vehicles that equipped with many safety features is advisable to enhance older and other drivers' safety. In addition, older driver license renewal may be modified to be required yearly to overcome early signs of fatigue or cognitive decline to reduce fatal crash risks and enhance safety. Therefore, the results and suggested countermeasures can provide guidance to improve safety of older drivers and other road users.
Book Synopsis New, Improved, Comprehensive, and Automated Driver's License Test and Vision Screening System by : Sandy H. Straus
Download or read book New, Improved, Comprehensive, and Automated Driver's License Test and Vision Screening System written by Sandy H. Straus and published by . This book was released on 2005 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
