| Title |
| Roadway Departure Crashes: Countermeasures and Their Potential Effectiveness (1 credit hours) |
| Course Description |
|
In this one hour online engineering PDH course, estimates are discussed of the crash reduction 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.

| Learning Objectives |
- Course participants are able to define “crash reduction factors.”
- Course participants are able to identify CRFs for barrier, bridge, geometric, median, roadside, and signs/markings/operational countermeasures.
- Course participants are able to explain how crash severity and road type are taken into account.
- Course participants are able to calculate the 95% confidence interval for the potential CRF that might be achieved by implementing the countermeasure.
