... With respect to strategies related to protective equipment, it will be difficult to identify crashes where more protective or more reflective clothing might be needed, but will be much easier to identify crashes in which the motorcycle operator was not wearing a protective helmet. In order to analyze the possible benefit of those truck or motorcycle strategies targeted to specific crash types or user subpopulations, crashes involving only the applicable subpopulations can be identified using variables in the table above (e.g., motorcycle operators not licensed to operate a motorcycle)

... link crashes to routes and search for the locations of "clusters" of target crashes for possible treatment, or (2) use a network screening program similar to that described under Procedure 2A to identify 1-mile sections with the highest crash frequency or total crash cost.
