Benefit to Attendees
The student will now have a detailed knowledge of the characteristics, analysis, and design of typical motor vehicle
This course provides the tools to the student for analyzing non-impact, low impact, and high impact motor vehicle barriers. Procedures are given for designing cable barriers, bollards, and rigid walls.
In this lesson, you are required to download and study the following course content in PDF format:
Please click on
the above underlined hypertext to view, download or print the document for your
study. Because of the large file size, we recommend that you first save the
file to your computer by right clicking the mouse and choosing "Save Target
As ...", and then open the file in Adobe Acrobat Reader. If you still experience
any difficulty in downloading or opening this file, you may need to close some
applications or reboot your computer to free up some memory.
The course provides sufficient explanations and procedures to
enable the student to analyze typical vehicle barriers, and to design cable barriers, bollards, and rigid walls.
Once you finish studying the above course content, you need to take a quiz to obtain the PDH credits.
