Enhanced Horizontal Curve Safety Treatments
Author: Gregory Taylor
The purpose of this course is to encourage you to use this information to evaluate problems and implement appropriate treatments for problem curve locations. These enhanced safety treatments can help reduce roadway departure crashes, injuries, and fatalities.
This course summarizes practical information on where, when, or how to apply enhanced safety treatments for horizontal curves. These treatments are relatively low cost versus geometric design improvements which can be more expensive. Information for each treatment generally includes description, application guidelines, design elements and materials, effectiveness (if available), and cost. Actual observed effectiveness values of a treatment can vary depending on its location.
Some of the traffic control devices or treatments presented in this course may be considered to be “experimental” and not compliant with the MUTCD.
Once you complete your course review, you need to take a multiple-choice quiz consisting of fifteen (15) questions to earn 3 PDH credits
