The Pedestrian and Bicycle Intersection Safety Indices (Ped ISI and Bike ISI) are a set of models that enable users to identify intersection crossings and intersection approach legs that should be the greatest priority for undergoing indepth pedestrian and bicycle safety assessment. This TechBrief summarizes the final report which had the development of these indices as its primary objective.

The proportion of the United States population age 65 and over will increase significantly in the coming decades. The effects of aging on people as drivers and pedestrians are highly individual. Challenges that may impact people as they age include declining vision, decreased flexibility and psychomotor performance, and changes in perceptual and cognitive performance. Design practices that explicitly recognize these changes will better serve this growing segment of the nation's population.
The Handbook augments the 2009 Edition of the Manual on Uniform Traffic Control Devices (MUTCD). The Traffic Control Devices Handbook, 2nd Edition provides guidance and information to implement the provisions of the MUTCD. The objective of the Handbook is to bridge the gap between the MUTCD requirements and field applications. Additional guidance is provided on the new MUTCD requirements to clarify these MUTCD provisions. The Handbook does not establish policy, procedures, or standards for an agency, or set the "standard-of-care" for decisions on traffic control devices.
"This chart summarizes studies about the effectiveness of engineering countermeasures. Studies where an increase in crashes were reported are also shown since this information is also relevant in selection of countermeasures."

The purpose of this report is to provide an overview of research studies on pedestrian safety in the United States;some foreign research also is included. Readers will find details of pedestrian crash characteristics, measures of pedestrian exposure and hazard, and specific roadway features and their effects on pedestrian safety.
