Emphasis Area Definition The term intersection crash is defined as
a crash which occurs just before, just after or inside the limits where two or more highways join or cross.
Emphasis Area Goals
To reduce the number of annual roadway intersection fatalities by 10 per year by December 31, 2014
To reduce the number of annual roadway intersection crashes involving incapacitating injuries by 100 per year by December 31, 2014
Intersection Emphasis Area Objectives
To implement cost-effective countermeasures at acceptable deployment levels to achieve the planned reduction in intersection fatalities and incapacitating injury crashes
To advance new strategies and concepts that support reductions in intersection fatalities and incapacitating injuries
Program projects from current year Intersection Emphasis List
CMF – 0.806 (CMFs for Changing Left Turn Phasing Paper 12-2521)
Implement Flashing Yellow Arrow where applicable
CMF ~ 78% for rear-end, wet road crashes (CMF Clearinghouse)
Implement High Friction Surface on applicable intersection approaches where applicable
