Audible Alert and TMA Lighting

What is the correct lighting/TMA package we should be using on TMAs? The Safety Focus Team has been sent multiple ideas from the districts regarding possible TMA lighting ideas for consideration. The Team put out a formal call to the districts to submit ideas for possible research. This project would work with FHWA to develop the research necessary to determine if the lighting suggestions improve driver attention and awareness to the TMA and provide the data needed to FHWA for acceptance. This project will also explore an updated Audible Alert system. Information would also be pulled from NCHRP project 05-24 to determine the lighting that was found to be effective during that study.
