Details

TRB will conduct a webinar on Monday, November 13, 2017 from 2:00 PM to 3:30 PM ET that features research from the National Cooperative Highway Research Program (NCHRP)’s Web-Only Document 227: Design Guidance for Interchange Loop Ramps and Pavements/Shoulder Cross-Slope Breaks.

This webinar will present information about how to develop improved design guidance for interchange loop ramps. Presenters will describe the new design guidelines based on observational field studies and safety analyses. They will also review AASHTO’s current design policy for cross-slope breaks on superelevated horizontal curves, based on vehicle dynamics simulation modeling and a crash analysis.

Some registrants will need to pay $95 to attend this webinar.  Sign into MyTRB.org to view registration information.

Webinar Presenters

  • Darren Torbic, MRI Global
  • Marcus Brewer, Texas A&M Transportation Institute

Moderated by: Aaron Frits, Kansas Department of Transportation

Webinar Outline

        1. Overview of NCHRP
        2. How to use the new guidelines for interchange loop ramps
        3. Review of AASHTO’s current design policy for cross-slope breaks on superelevated horizontal curves
        4. Question and answer session

The first 60 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions. The Registered Continuing Education Program (RCEP) categorizes this webinar activity as relating to health, safety, and welfare including core technical.

Learning Objectives

At the end of this webinar, participants will be able to:

  • Describe how to use the new design guidelines for loop ramps at service interchanges in both rural and urban areas
  • Describe how to implement the Highway Safety Manual ramp crash prediction methodology to analyze the safety impacts of loop ramps and other ramp configurations
  • Summarize research that supports AASHTO’s current design policy for cross-slope breaks on superelevated horizontal curves
  • Apply mitigation measures that reduce maximum roll angles experienced by errant vehicles that encroach onto the shoulders

 

Professional Development Hour Information

A certificate for 1.5 Professional Development Hours (PDHs) will be provided to Professional Engineers (PEs) who register and attend the webinar as an individual. For groups, only the person that registers and attends the session will receive a PDH certificate. Certificates of Completion will be issued only to individuals who register for and attend the entire webinar session.

Individuals registered as Florida PEs are no longer required to email TRB with your license number to report your attendance. Instead, please use your certificate that TRB provides through RCEP.net as verification of your attendance to the Florida Board of Professional Engineers.

Please check with your licensing board to ensure that TRB webinar PDHs are approved by your board.

This webinar was developed in March 2017. TRB has met the standards and requirements of the Registered Continuing Education Program (RCEP). Credit earned on completion of this program will be reported to RCEP by TRB. Complaints about registered providers may be sent to RCEP, 1015 15th Street, NW, 8th Floor, Washington, DC 20005.
