This report incorporates new research findings & technical developments & extensive feedback from State, county, & municipal engineers who reviewed & applied recommendations. Guidance on how & when to implement the included recommendations is included, as well as codes that indicate at a glance the relationship of each recommendation to standard design manuals. Included recommendations are directed toward new construction, reconstruction, scheduled maintenance, & spot treatmentsÓ to ameliorate demonstrated safety problems, emphasizing countermeasures with modest additional cost during installation & the potential for cost savings over the life cycle. Illustrated.
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.
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 348: Improving the Safety of Older Road Users examines programs and policies in place across the country to improve the safety and mobility of older road users. The report documents a range of strategies and related programs under way in roadway engineering, driver licensing, public information and education, and enforcement and adjudication.
This article explains why safety for elderly drivers and pedestrians is an issue. Information is provided on the changing age structure in Canada and the importance of mobility, followed by a discussion of older people and the problems they face on the road. It addresses the age-related changes individuals often experience that can affect mobility, and includes a discussion of environmental factors that may have an impact on older drivers and pedestrians. It concludes with an overview of some possible countermeasures that could be taken by the elderly individual, urban developers, highway planning departments and others who are concerned about these issues.
Developed guidelines for changes in the geometric design & operations at intersections to aid in their use by older drivers & pedestrians. A lit. review identified age-related diminished capabilities that affect performance at intersections, & examined current design standards & their adequacy for older road users. A set of problem identification studies were conducted to better define older persons' difficulties in intersection use, & an expert panel met to prioritize variables for more extensive lab. & field studies. These studies subsequently focused on age & the effects of opposite left-turn geometry, right-turn channelization & curb radius, & varying median pedestrian refuge island configurations, using both objective & subjective measures.
