A Multivariate Analysis of Crash and Naturalistic Driving Data in Relation to Highway Factors (SHRP 2 Report S2-S01C-RW-1)

Greetings!
In anticipation of the large volume of data to be collected during the SHRP 2 naturalistic driving study (NDS), several projects were undertaken to demonstrate that it is possible to use existing NDS data and data from other sources to further the understanding of the risk factors associated with road crashes. More specifically, the four projects conducted under the title Development of Analysis Methods Using Recent Data examined the statistical relationship between surrogate measures of collisions (conflicts, critical incidents, near collisions, or roadside encroachment) and actual collisions. This report describes the approach developed in Project S01C, which is based on a unified statistical analysis of crash data and surrogate events using a spatial referencing system and a common measure of exposure.
