abstract="This paper is the fourth and last in a series of articles about a major study of delays at pedestrian crossing facilities - Zebra crossings and Fixed-Time and Vehicle Actuated Pelicans. This article provides mathematical relationships which link pedestrian and vehicle delays to flow levels and other crossing parameters and indicates some general applications of the study.<p />",
