PURPOSE The Federal Highway Administration (FHWA) proposed guidelines for highway design to increase the safe driving ability of older drivers; however, little empirical evidence exists to support the effectiveness of these guidelines. The purpose of this study was to investigate the effects of implementing these guidelines (in 4 pairs of intersections) on(More)
OBJECTIVE To test the effectiveness of the FHWA guidelines for intersection design. METHODS In an experimental design we used kinematics measures from an instrumented vehicle and behavioral (error) data collected during on-road evaluations to quantify the effects of improved versus unimproved intersections (turn phase) and to determine if these(More)
On December 1 and 2, 2003, 63 international experts on older driver issues met to examine three critical issues related to the safe mobility of older drivers. Conference participants addressed standards and protocols for screening and evaluating the skills of older drivers. For drivers judged to lack the necessary skills to drive safely, participants(More)
