Travel Time Reliability

March 11, 2010

Travel time reliability is a measure that's becoming increasingly important to public agencies, elected officials, and most importantly the traveling public. The reliability concept is less than a decade old and continues to be explored and advanced through research programs, such as the Strategic Highway Research Program 2. On March 4th, the Portland office of KAI led a workshop about the history and current state of the practice of reliability, key concepts and performance measures, and a description of how reliability concepts can be (and will be) applied to mainstream traffic operations and planning activities in the near future.

The presenter, Brandon Nevers, has over 13 years of experience in transportation research, traffic operations and design, long-range planning, pedestrian safety, and parking. He is a senior researcher for three projects within the federally authorized Strategic Highway Research Program 2 related to network capacity and travel time reliability. He is also the Principal Investigator for NCHRP 3-98: Guidelines on the Use of Auxiliary Through Lanes at Signalized Intersections. He is a member of the Signalized Intersection Subcommittee of the Transportation Research Board’s Highway Capacity and Quality of Service Committee and is a board member for the Washington DC Section of the Institute of Transportation Engineers.
