What Can Near-Misses Tell Us about the Risk of Actual Collisions? A New Report from the SHRP 2 Driving Study
|
|
Greetings!
In anticipation of the large volume of data to be collected during the SHRP 2 naturalistic driving study (NDS), several projects were conducted to demonstrate that it is possible to use existing data from previous naturalistic driving studies and data from other sources to further the understanding of the risk factors associated with road crashes. More specifically, the four S01 projects, entitled Development of Analysis Methods Using Recent Data, examined the statistical relationship between surrogate measures of collisions (conflicts, critical incidents, near collisions, and roadside encroachment) and actual collisions. SHRP 2 Report S2-S01B-RW-1: Analysis of Existing Data: Prospective Views on Methodological Paradigms presents the results of one of these projects. The primary objective of this project was to investigate structured modeling paradigms for analysis of naturalistic driving data (NDD). Five research questions were identified and various models (such as, event-based models and categorical-outcome models) were applied to NDD to determine appropriateness for analysis and suggestions for future analyses.
