              Abstract:The objective of the Transportation Pooled Fund Program’s Traffic Control Device (TCD) Consortium is to assemble a consortium of regional, State, and local entities, other appropriate organizations, and the Federal Highway Administration 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 and interim approvals.



The purpose of this study is to explore driver behavior when exposed to four warning signs: two advance warning signs, and two lane line transition markings. This study quantifies driver behavior by investigating when drivers recognize that the lane would end, prepare to change lanes, and execute a lane change. The goal of this work is to assess driver understanding and behavior when faced with new and traditional lane-reduction roadway markings and signing.



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