Identification of General Risk-Management Countermeasures for Unsafe Driving Actions. Volume III: A Definitional Study of Speeding, Following Too Closely, and Driving Left of Center

摘要

The report develops a set of operational definitions for three unsafe driving actions (UDAs): speeding, following too closely, and driving left of center. The definitions flow from a methodological development and from an analysis of the literature and accident files at HSRI. Risk statements for these UDAs also are developed, along with a description of the circumstances under which the UDAs occur. It is recommended that the speed UDA be the target for countermeasure development in this project. The report is a part of a larger study to identify promising countermeasures for high-priority UDAs.
