When signage on a rural highway in Kansas was upgraded, the State received some comments that begged the question of whether modern highly reflective sign sheeting materials could, in some circumstances, actually decrease the legibility of signage, particularly for older drivers. Older drivers tend to have poorer visual acuity, requiring larger signs to provide the same legibility as found in a younger population. However, older drivers also tend to be more sensitive to glare and slower to recover from glare blindness. This study was conducted to determine if highly reflective sheeting could cause a reduction in sign legibility due to veiling glare, especially in older drivers. The test was conducted using 60 drivers in an actual automobile and full scale signs and distances. The data collection was conducted in a test facility where external factors could be eliminated, isolating the variables of greatest interest. Older drivers as a whole were found to exhibit poorer performance in terms of visual acuity and response time, but no detrimental effects attributable to glare were observed.

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.

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.

The objectives of this project were to define the problems older drivers and pedestrians have at intersections, and make recommendations for changes. A literature review, a detailed accident analysis, and eight focus groups were conducted to identify the specific kinds of traffic-control-related problems experienced by older drivers and pedestrians at intersections. Three problem areas were targeted. The Left-Turn Signal Comprehension Study examined the lack of understanding associated with a variety of protected and permitted left-turn signal displays. Older pedestrians frequently indicated that they don't have enough time to cross the street. This complaint is exaggerated by the lack of understanding of the clearance--Flashing DON'T WALK--phase. The Driver Signal Response and Stopping Behavior Study compared the responses of older and younger drivers to amber onset and the braking ability of older and younger drivers.
