COURSE DESCRIPTION:

Beginning with an introduction to intersection and crash characteristics, this course provides information on ready-to-use, direct-application safety measures for rural unsignalized and signalized intersections. Participants are presented with a synthesis of countermeasures and their associated crash reduction factors as identified in the "AASHTO Strategic Highway Safety Plan - NCHRP 500 Guidebooks." The course focuses on the application of these countermeasures and design and safety operations best practices for substantive improvements to intersection safety. During the course, participants have the opportunity to present intersection safety situations that they are currently facing and discuss appropriate countermeasures and best practices to address those situations.

OUTCOMES:

Upon completion of the course, participants will be able to:

• Apply models (equations) to predict the number of crashes for an intersection based upon traffic volumes
• Identify high crash intersections and recognize appropriate engineering countermeasures
• Identify crash reduction factors/crash modification factors associated with countermeasures
• Describe safety performance of intersection geometric design features and the models to quantify the safety effect
• List regulatory, warning, and guide signing and markings countermeasures and associated safety benefits
• List highway lighting countermeasures and associated safety benefits
• List traffic signal countermeasures and associated safety benefits

TARGET AUDIENCE:

Federal, State, and local transportation traffic and safety engineers, and planners involved in reducing intersection crashes.
