Midwest Smart Work Zone Deployment Initiative Year 3: Fluorescent Yellow-Green Background for Vehicle-Mounted Work Zone Signs

As a part of the Midwest States Smart Work Zone Deployment Initiative (MwSWZDI) Year 3, the impact of the FYG background on improving drivers’ lane-changing behavior in advance of a work zone was evaluated. Furthermore, a motorists survey was conducted at interstate rest areas. The Center for Transportation Research and Education (CTRE) deployed the background during a simulated moving work zone operation on multilane divided highways. The purpose of the study was to examine the effects of the FYG background in encouraging approaching motorists to merge to the open lane sooner. This report presents the evaluation strategies and results.
