ABSTRACT
Channelizing devices are often used in conjunction with signage within work zones to guide traffic. These channelizing devices can obscure drivers’ vision of the signage. The objective of this project was to evaluate the AASHTO MASH compliance of a tall portable sign stand which raises the sign above the channelizing devices. The research team first reviewed previous literature and current state standards. Subsequently, the research team selected a design for MASH crash testing. This report documents this effort and provides recommendations for future research. The research team evaluated three different designs through MASH crash testing. All three designs failed to meet MASH evaluation criteria in either test 3-71 or 3-72. The research team recommends additional research projects to continue this investigation.
