NCHRP 3-70, Multimodal Level of Service Analysis for Urban Streets, is developing and testing a framework and enhanced methods for determining levels of service for the automobile, transit, bicycle, and pedestrian modes on urban streets. This paper presents the proposed Pedestrian Level of Service (LOS) Model for Arterials, developed as part of NCHRP 3-70. This effort represents a progressive shift in evaluating the quality of service from a provider based measure (how many vehicles/pedestrians can we move and how fast) to a user based measure (how well do drivers/pedestrians feel the facility meets their needs). To obtain feedback from potential pedestrian facility users, data for the model were obtained from participants in video simulation laboratories. The participants watched video clips of roadways and intersections and provided their ratings as to how well the depicted roadways and intersections would meet their needs as pedestrians. The proposed model consists of a pedestrian density LOS and a pedestrian non-density LOS. The density LOS is computed according to the methods provided in the Highway Capacity manual. The non-density LOS is a function of the pedestrian LOS of roadway segments, the pedestrian LOS of intersections, and the roadway crossing difficulty factor.
