PASSING PERFORMANCE MEASUREMENTS RELATED TO SIGHT DISTANCE DESIGN

A PROPOSED PASSING SIGHT DISTANCE DESIGN CONCEPT, BASED ON THE SAFETY, OPERATIONAL AND LEGAL ASPECTS OF THE PASSING MANEUVER, INTEGRATES DESIGN AND STRIPING. PASSING MANEUVERS UNDER ACTUAL HIGHWAY OPERATING CONDITIONS WERE PHOTOGRAPHED AND ANALYZED TO DETERMINE OPERATIONAL CHARACTERISTICS DURING HIGH-SPEED MANEUVERS. MINIMUM PASSING SIGHT DISTANCES AND DESIRABLE LENGTHS OF PASSING ZONES ARE RECOMMENDED. NEW APPLICATIONS OF THE PROPOSED DESIGN CONCEPT THAT CONSIDERS BOTH THE REQUIRED SIGHT DISTANCE AND ZONE LENGTH ARE DISCUSSED. /AUTHOR/
