Effectiveness of Countermeasures for Roadway Departure Crashes
This online engineering PDH course provides estimates about crash reduction to be expected if various countermeasures are implemented with respect to roadway departure and other non-intersection crashes.
The estimates are presented as Crash Reduction Factors (CRFs). Traffic engineers and other transportation professionals can use the information contained in this course when asking the following types of question: Which countermeasures might be considered along a particular section of a highway that is experiencing a high number of roadway departure crashes? What changes in the number of roadway departure crashes can be expected with the implementation of the various countermeasures? To answer questions like these, in this course CRFs are presented in separate tables for barrier, bridge, geometric, median, roadside, and signs/markings/operational countermeasures.
This 1 PDH online course is intended for traffic engineers and other transportation professionals concerned with the design of roadways.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Familiarizing with “crash reduction factors”
- Learning how to identify CRFs for barrier, bridge, geometric, median, roadside, and signs/markings/operational countermeasures
- Understanding how crash severity and road type are taken into account
- Knowing how to calculate the 95% confidence interval for the potential CRF that might be achieved by implementing the countermeasure
