Book Description
As people age, their physical, visual, & cognitive abilities may decline, making it more difficult for them to drive safely. Older drivers are also more likely to suffer injuries or die in crashes than drivers in other age groups. These safety issues will increase in significance because older adults represent the fastest-growing U.S. population segment. This report examined: (1) what the fed. gov¿t. has done to promote practices to make roads safer for older drivers & the extent to which states have implemented those practices; (2) the extent to which states assess the fitness of older drivers & what support the fed. gov¿t. has provided; & (3) what initiatives selected states have implemented to improve the safety of older drivers. Includes recommendations. Illustrations.

Book Description
Rapid increases are estimated in the percentage of elderly among the U.S. population starting in 2010. A majority of the older Americans depend on automobiles to meet their transportation needs either because of lack of public transportation or by choice. Ninety percent of total trips made by the elderly are by personal vehicle and seventy percent of this number involves the elderly driving the vehicles. However due to the aging process, older drivers experience a natural decline in sensory, cognitive, and other mental and physical capabilities as compared to younger drivers. This situation, combined with an imperfect highway infrastructure is making older drivers one of the most critical groups in terms of highway safety, thus demanding safer driving conditions. Safety concern for older drivers arises when the fatality rate per mile driven is considered, as exposure is one of the crucial factors contributing to increased fatality risk of older drivers. Hence, exposure reported in Billion Vehicle Miles Traveled (BVMT) was considered for this study. Crash data and exposure data were used to compute the fatality rates. Sources for this data are the Fatality Analysis Reporting System (FARS) and National Household Travel Survey (NHTS). A basic characteristics study was completed to compare the fatality risk of younger (16-24 yrs), middle-aged (25-64 yrs), and older drivers (65+ yrs). Crash details were screened to study the characteristics of older drivers involved in fatal crashes. Risk for older drivers due to other involved drivers of all ages divided into groups was studied to understand their distribution. A number of statistical methods like the chi-square test of independence, odds ratio and double paired comparison estimates were applied to study contributing factors of older driver's increased fatal crash involvement. Results from the characteristics study for the elderly indicate that a majority of fatal crashes occur under daylight conditions with relatively higher seatbelt usage and non-alcoholic driving on straight level roads, which are generally considered as safer driving conditions. Other factors studied include vehicle-related variables like body type; manner of collision; roadway-related variables like roadway function class, month of the crash, and day of the week; and driver-related variables like race. Roadway functional class, vehicle body type, travel speed, number of drunk drivers, and the month in which the fatality occurred were found to have strong correlation with age of the older driver. Results from paired comparisons were used to estimate the fatality risk of older occupants as drivers and passengers under two different conditions considered simultaneously. Older drivers were found to have more fatality risk compared to older passengers. Recommended measures are also discussed to enhance older driver safety in the U.S.

Book Description
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 Description
By the turn of the century, the elderly will comprise about 20 percent of the population in North America, and 28 percent of those who drive. Place this percentage in high-powered automobiles, and the need for planning and policy development becomes evident. Most standard research on elderly drivers has not gone beyond gathering data on specific situations or characteristics. This book rises beyond simple statistical presentation. It blends sociological insight with statistical detail to produce an absorbing description of the elderly drivers' daily lives, driving styles, experiences with accident and injury, social relationships, and life aspirations. It also describes areas of neglect: imagined and real health problems, driving exposure and traffic violations, accidents, and loss of self-esteem. It presents In-depth accounts of the trauma of loss of license and the Importance of the automobile for sustaining mental, physical, and social well being. The self-Imposed or self-defined rules elderly drivers use to navigate traffic or compensate for physical frailities are described in depth. The Safety of Elderly Drivers Includes penetrating comments from elderly drivers who have been involved in serious accidents, and from random elderly drivers speaking for their generation of drivers. Integrating statistical findings based on Motor Vehicle Department accident data and survey data with comprehensive interviews and discussions with elderly drivers. the book provides an emperically grounded. In-depth view of the elderly driver today. Rothe summarizes theories and models of aging. along with past research on elder[y drivers. projecting what the future may hold If present trends in medicine. housing. politics. migration. and mass transit continue. It closes with a series of recommendations for future traffic planning. This book will be of Interest to policymakers concerned with traffic safety, as well as social scientists and others Interested In gerontological issues.

Book Description
The authors examined if the presence of passengers affects the risk of making unsafe actions among older drivers, and determined what specific types of unsafe actions may be affected (positively or adversely) by the presence of passengers. They used 1975 to 1998 data from the U.S. Fatality Analysis Reporting System (FARS); unsafe actions were based on driver-related factors. The authors calculated the odds ratio (OR) of making unsafe driving actions in the presence of passengers compared to situations where drivers were alone. In general, the presence of passengers was beneficial to older drivers (e.g., for drivers aged 65 to 79 with four or more passengers, OR = 0.73 [99% Confidence interval[CI] = 0.61, 0.86. For drivers aged 65 to 79, the presence of passengers was associated with a reduced risk of some unsafe actions (e.g., driving the wrong way, OR = 0.37 [95% CI = 0.30, 0.46]) but a higher risk of other actions (e.g., ignoring signs/warnings/right of way, OR = 1.18 [95% CI = 1.15, 1.22]). These findings are discussed in the context of strategies to maximize safe driving in older adults.
