Corridor Studies 12

Corridor Studies • Corridor Studies • Can help analyze crash patterns along a corridor • Tabular data • Graphical data

Intersection Studies 14

Intersection Studies • Intersection Studies • Can help analyze crash patterns at an intersection • Tabular data • Collision Diagrams

Intersection Studies • Intersection Studies • Can help analyze crash patterns at an intersection • Tabular data • Collision Diagrams • MicroStation add-in

Highway Safety Improvement Program (HSIP) 17

HSIP • HSIP Purpose • To reduce the number and severity of crashes, and to reduce the potential for crashes on all public highways • Provides a systematic procedure that identifies, reviews and addresses traffic safety concerns throughout the state. 2014 Safety Warrants Intersection Warrants: • I-1: Frontal Impact • I-2: Last Year Increase • I-3: Severity Index • I-4: Night Condition • I-5: 10-Year Chronic Crossing Pattern Section Warrants: • N-1 and F-1: Run Off Road during Wet Road Conditions • N-2 and F-2: Run Off Road • N-3 and F-3: Wet Road Condition • N-4 and F-4: Night Condition Bicycle and Pedestrian Intersection Warrant: • BP-1 Chronic Location

HSIP • HSIP Reports
