Countermeasures for Intersection Crashes
This online engineering PDH course presents estimates of the crash reduction that might be expected if a specific countermeasure or group of countermeasures is implemented with respect to intersection crashes.
The course presents crash reduction estimates as Crash Reduction Factors (CRFs). A CRF is the percentage crash reduction that might be expected after implementing a given countermeasure. One CRF is provided for each countermeasure. CRFs are presented in separate tables for signalization, geometric, and signs/markings/operational countermeasures. Traffic engineers and other transportation professionals can use the CRFs when asking the following types of question: Which countermeasures might be considered at the signalized intersection of Maple and Elm streets, an intersection experiencing a high number of total crashes and left-turn crashes? What change in the number of total crashes and left-turn crashes can be expected with the implementation of the various countermeasures?
The 1 PDH online course is intended for traffic engineers and other transportation professionals concerned with accident prevention at intersections.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Familiarizing with “crash reduction factors”
- Familiarizing with CRFs for signalization, geometric, and signs/markings/operational countermeasures
- Knowing how crash severity is taken into account in choosing an appropriate countermeasure
- Understanding how existing control information, such as no signal, signal, stop, or stop/yield is taken into account in choosing an appropriate countermeasure
