Pedestrian research involves a wide range of topics, from designing individual crosswalks and intersections to accommodate all pedestrians, to installing continuous sidewalks throughout neighborhoods and roadway corridors, to altering roadway design to slow traffic, to providing pedestrian access to buildings and transit stops. Research on signal timing, intelligent transportation systems (ITS) applications, the design of sidewalks and crossings, driver yielding behavior, and pedestrian detection should consider impacts on different groups of pedestrians, including children, the elderly, and people with all types of physical disabilities, including those in human-powered and motorized wheelchairs. When the word "pedestrian" is used in this document, it refers to all types of pedestrians. This document presents the top 16 pedestrian Research Problem Statements, prioritized from a list of approximately 80 Research Problem Statements by the Transportation Research Board Committee on Pedestrians
