IAP Project: Evaluation of Work Zone Safety Using the SHRP2 Naturalistic Driving Study Data

Project Description This research was sponsored by Federal Highway Administration Implementation Assistance Program. The purpose of this effort is to support the use of various components of the SHRP2 Naturalistic Driving Study database by personnel from CTRE/ISU. The main objective of this project is to identify factors contributing to roadway work zone crashes/near crashes and develop a proof of concept to evaluate work zone risk for three to four roadway types. Data Request Scope This study will look at driver, environmental, roadway, and vehicle factors that contribute to work zone crashes and near crashes. The study will also evaluate how drivers negotiate work zones. Data Specification The dataset delivered for this AASHTO Implementation Assistance Program project consisted of a sample of detailed event tables (including trip summaries, vehicle, and driver survey results), forward video, and time series variables for 243 crash-related events and 420 baseline events from the SHRP2 NDS.
