                Lane Line Markings in Advance of Lane-Reduction Transitions
FHWA-HRT-23-009.pdf (847.75 KB)
      
  Publication Information
                  Publication Type:Technical Report
                  Publication Number:FHWA-HRT-23-009
              Abstract:The objective of the Transportation Pooled Fund Program’s Traffic Control Device (TCD) Consortium is to assemble a consortium of regional, State, local entities, appropriate organizations, and the Federal Highway Administration (FHWA) to establish a systematic procedure to select, test, and evaluate existing and new TCDs that will support changes to the Manual on Uniform Traffic Control Devices (MUTCD) and interim approvals.



This report documents a FHWA project examining the comprehension of different lane-reduction markings. The goal of this study was to determine the effects of the different line-marking patterns in terms of merging behavior at lane-reduction transitions, driver understanding of the intended message conveyed at lane-reduction transitions, and perceived ranking of effectiveness.



This report is of interest to engineers, planners, and other researchers and practitioners who are concerned with the limits of road users’ ability to comprehend and follow roadway lane-reduction transitions correctly.
