TRB will conduct a webinar on Tuesday, February 19, 2019 from 2:00 PM to 3:30 PM ET that will discuss strategies for bottleneck identification, diagnosis, and mitigation. Traffic bottlenecks in the United States are worsening, and states must manage their bottleneck problems with minimal funding. Therefore, it is necessary to demonstrate a return on investment regarding bottleneck mitigation strategies. The presenter will identify how bottleneck intensity and frequency can be precisely determined in ways that account for visibility and weather. He will evaluate low-cost bottleneck mitigation strategies, identify bottleneck treatments, and discuss the Congestion and Bottleneck Identification (CBI) tool.

This webinar was organized by the TRB Standing Committee on the Operational Effects of Geometrics.

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

Webinar Presenter

• David Hale, Leidos

Moderated by: Sarah Binkowski, Southeast Michigan Council of Governments

Webinar Outline

1. Bottleneck identification, performance measures, and bottleneck rankings, including case studies using the CBI tool
2. Conditions under which certain low-cost bottleneck mitigation strategies (extending acceleration lanes, hard shoulder running, dynamic lane grouping, lane narrowing, innovative intersections) are likely to be effective
3. Innovative bottleneck treatments (contraflow left-turn intersections, contraflow left-turn intersections, dynamic hard shoulder running)
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.

Learning Objectives

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

• Identify measures to mitigate bottlenecking
• Evaluate bottlenecking treatments

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 approved webinars, TRB’s webinar program awards Registered Continuing Education Provider (RCEP) Professional Development Hour (PDH) credits associated with participation only to the registered individual and not  to other members of a group that view the webinar together. To receive PDH credits, please register as an individual and sign into the webinar from your personal computer. After doing this, you may join your group in a meeting room.  To be eligible for the credits, individuals must remain signed in for the entire webinar, including for any question and answer session following the presentations.

In addition, advance registration is available until just before the webinar starts. Once the webinar starts, you will be unable to submit your registration. Individuals that are registered for a webinar but do not receive their confirmation emails due to their organization’s internal firewalls should contact the TRB Helpdesk (MyTRB@nas.edu) for assistance in signing in.

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 2018. 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.
