TRB Webinar: Guidelines on the Use of Auxiliary Through Lanes at Signalized Intersections

TRB conducted a webinar on July 11, 2012, from 2:00 p.m.-3:30 p.m. ET that explored a National Cooperative Highway Research Program (NCHRP) Report 707: Guidelines on the Use of Auxiliary Through Lanes at Signalized Intersections. Contact Reggie Gillum at RGillum@nas.edu for a link to the recorded webinar.

An Auxiliary Through Lane (ATL) is a limited-length through lane added upstream and downstream of an intersection. NCHRP Report 707 provides guidelines that are intended for use in the justification, design, and analysis of ATLs to assist practitioners in the effective and safe application of ATLs at signalized intersections.  

This webinar will provide an overview of the guidelines, including a summary of specific user considerations, operational and safety methods for evaluating ATLs, and an approach for preparing a functional design plan for an ATL.  

Webinar presenters and presentation outline:
  1. Brandon Nevers, Kittelson & Associates, Inc.
    ATL Guidelines Overview and User Needs
    -  Highlight document structure
    -  Describe User Needs

  2. Nagui Rouphail, Institute for Transportation Research and Education at North Carolina State University
    Operational Evaluation Method
    -  Describe operational results from field evaluation
    -  Describe method for evaluating ATL operational performance 

  3. Zachary Bugg, Institute for Transportation Research and Education at North Carolina State University
    Safety Evaluation Method
    -  Describe safety results from field evaluation
    -  Describe method for evaluating ATL safety performance

  4. Hermanus Steyn, Kittelson & Associates, Inc.
    Geometric and Traffic Design Approach
    -  Identify design characteristics of ATLs
    -  Describe method for estimating ATL length Describe sample problem application 
Moderated by: Brent Sweger, Kentucky Transportation Cabinet

Webinar learning objectives:
After participating in the webinar, attendees should be able to:
  • Define the scope and application of NCHRP 707;
  • Describe operational, safety, and design evaluation methods and approaches; and,  
  • Apply evaluation procedures to a sample problem.
