Abstract This guide describes scalable risk assessment methods for pedestrians and bicyclists, wherein risk is a measure of the probability of a crash to occur given exposure to potential crash events. This guide outlines eight sequential steps to develop risk values at various desired geographic scales, and describes the scope and nature of each step, including any guiding principles. Exposure to risk is an integral element of risk, and as such, an integral element of the pedestrian and bicyclist risk assessment methods in this guide. Exposure is a measure of the number of potential opportunities for a crash to occur, and is often directly related to the number of people who walk and bike. This guide provides information on analytic methods to estimate pedestrian and bicyclist exposure, and identifies other relevant guides and resources that provide supplemental information for exposure estimation. Depending upon the desired geographic scale, one or more of these three analytic methods can be used to estimate pedestrian and bicyclist exposure: 1) site counts; 2) travel demand estimation models (several different types); and, 3) travel surveys.
