Chapter 4: Exposure Analysis on Specific Transportation Facilities: Synthesis of Methods for Estimating Pedestrian and Bicyclist Exposure to Risk at Areawide Levels and on Specific Transportation Facilities

This report summarizes the variety of methods used to estimate and evaluate exposure to risk in pedestrian and bicyclist safety analyses. In the literature, the most common definition of risk was a measure of the probability of a crash to occur given exposure to potential crash events. There was also consensus on a theoretical definition of exposure as a measure of the number of potential opportunities for a crash to occur. However, there is wide divergence on operational definitions of exposure, and an even wider range of exposure measures being used in practice.

Pg 13-25: Pedestrian Traffic Fatalities by State

GHSA's Pedestrian Traffic Fatalities by State: 2020 Preliminary Data and subsequent addendum offer the first comprehensive look at state and national trends in pedestrian deaths for the full year (January-December). The report projects the U.S. pedestrian fatality rate per billion vehicle miles traveled (VMT) jumped to 2.3 deaths in 2020 – an unprecedented 21% increase from 1.9 in 2019.

Pg 65-72: FHWA Course on Bicycle and Pedestrian Transportation

This Student Workbook contains 24 lessons of resource material that is intended for use in university courses on bicycle and pedestrian transportation. The lessons span a wide range of topics including an introduction to bicycling and walking issues, planning and designing for bicycle and pedestrian facilities, and supporting elements and programs. This is the second edition of the Student Workbook;the first edition was published as Report No. FHWA-RD-99-198.

Pg 23-30: Pedestrian and Bicyclist Road Safety Assessments

Beginning in the fall of 2014, the United States Department of Transportation (U.S. DOT) field offices began organizing pedestrian and bicycle safety assessments, on-the-ground examinations of transportation facilities conducted by a multidisciplinary, multi-agency team.

Pg 103-116: Guidebook on Pedestrian and Bicycle Volume Data Collection (NCHRP Report 797)

TRB’s National Cooperative Highway Research Program (NCHRP) Report 797: Guidebook on Pedestrian and Bicycle Volume Data Collection describes methods and technologies for counting pedestrians and bicyclists, offers guidance on developing a non-motorized count program, gives suggestions on selecting appropriate counting methods and technologies, and provides examples of how organizations have used non-motorized count data to better fulfill their missions.
