Evaluation of Data Needs, Crash Surrogates, and Analysis Methods to Address Lane

Evaluation of Data Needs, Crash Surrogates, and Analysis Methods to Address Lane: Departure Research Questions Using Naturalistic Driving Study Data
The second Strategic Highway Research Program (SHRP 2) Report S2-SO1E-RW-1
TRB, NAS Press | 2011 | ISBN: 9780309129015 | 152 pages | PDF | 7 MB

This report examines the statistical relationship between surrogate measures of collisions (conflicts, critical incidents, near collisions, or roadside encroachment) and actual collisions.

The primary objective of the work described in this report was to investigate the feasibility of using naturalistic driving study data to increase the understanding of lane departure crashes.
