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)
There has been a long-recognised association between extent of driving and crash involvement: the lower the annual mileage driven, the higher the per-distance crash rate. Because older drivers generally drive less distance per year than others, this association has been used to explain much of their apparent over-involvement in crashes. Several studies from(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)
