Abstract
Senior citizens now constitute the fastest growing segment of the United States population, and an increasing number of older adults will continue to travel, both as drivers and as pedestrians, as they age. As a result, transportation engineers will be faced with additional challenges to meet the mobility needs of older road users. In response to this demographic shift, this report addresses the need to integrate the existing wealth of older traveler research into a set of guidelines for application to transportation systems. This research effort had as its objective the cataloging of those research results that could be applied directly to elements of state and federal transportation systems. (A)
