Systemic Pedestrian Safety Analysis: Contractor's Technical Report
NCHRP Project 17-73
Source: National Cooperative Highway Research Program and Transportation Research Board (TRB)
The objective of this research was to develop a process, detailed in the Systemic Pedestrian Safety Analysis Guidebook, for (1) conducting systemic pedestrian safety analysis using robust analytical techniques to identify roadway features and other risk factors to consider in a systemic pedestrian safety process; (2) identify appropriate and cost-effective systemic pedestrian safety improvements to address the associated risk factors; and (3) enable transportation agencies to prioritize candidate locations for selected safety improvements based on risk.
To develop the process and related Guidebook, the team performed the following key tasks: (1) conducted a literature review and practitioner interviews to identify systemic processes used by agencies; (2) identified data needs and sources for a robust systemic pedestrian assessment; (3) compiled risk factors (associated with pedestrian crash frequency and/or severity) from published analyses; (4) conducted negative binomial regression analysis of a network-wide database to identify risk factors associated with pedestrian collisions occurring at segments and to demonstrate an analysis approach; (5) reviewed and identified a select set of candidate pedestrian crash countermeasures compatible with systemic processes; and (6) developed case examples describing real or hypothetical applications of a robust systemic pedestrian safety process.
