15-2 Using the New SHRP2 Naturalistic Driving Study Safety Databases to Examine Safety Concerns for Older Drivers

Project Objectives

This project aims to address highway safety challenges by funding research using the SHRP2 NDS and RID data to examine intersection safety for drivers 65 and older.  This study will utilize a phased approach with Phase I constituting a preliminary examination of the data, some safety analysis for proof of concept and insights into its application for improving intersection safety for this age group and some data analysis.  Phase II will be based on the success of Phase I.  Research in the second phase shall define and undertake innovative approaches that ultimately provide advancements in the study of road crashes and/or implementable solutions to real-world problems.  The program shall ultimately lead to final deliverables that have direct value to highway safety practitioners at the State and local level.

Implementation Activities

This study confirmed for five states that older drivers tend to have more crashes as signalized intersections. These states will use the information as a basis for further research and/or as information to share with older drivers.
