Basic Horizontal Curve Safety Treatments
Author: Gregory Taylor
The purpose of this course is to present basic safety treatments that may be used for problem horizontal curve locations. These treatments can be used to reduce and/or prevent roadway departure crashes, injuries, and fatalities.
This course summarizes practical information regarding the application of basic MUTCD safety treatments (signs, pavement markings, and delineators) for roadway horizontal curves or winding sections. The treatments presented are relatively low cost versus more expensive geometric design improvements (degree of curve, shoulders, superelevation, curve length, cross-section, etc.). Basic information for each treatment typically includes description, application guidelines, design elements, materials, effectiveness, and cost.
Estimates for treatment effectiveness in reducing crashes were included if available. Actual observed treatment effectiveness may vary depending on its location.
