The Surface Transportation Technical Group (STTG) provides a forum for individuals involved or interested in human factors to exchange information, methodologies, and ideas related to the international surface transportation field. Surface transportation encompasses numerous mechanisms for conveying humans and resources: passenger, commercial, and military vehicles, on- and off-road; mass transit; maritime transportation; rail transit, including Vessel Traffic Services (VTS); pedestrian and bicycle traffic; and highway and infrastructure systems, including Intelligent Transportation Systems (ITS).
All officers serve one-year terms (calendar year). The Technical Group Vice Chair and Technical Group Vice Program Chair automatically become Chairs of the respective positions after one calendar year and a call for nominations is issued each fall for new Vice Chairs.
