Abstract
Walking speeds of pedestrians are used to determine the pedestrian clearance interval of pedestrian signals or, in those cases where ther are no pedestrian signals, to obtain the minimum green time for concurrent traffic. Elderly pedestrians are a growing component of the North American population. Their growing numbers raise the question of the suitability of the assumed normal walking speed used to determine the pedestrian clearance interval. The purpose of this paper is to report the findings of a study which measured the walking speed of elderly pedestrians at various types of crosswalks. (A)
