In environments such as office buildings, shopping malls, airports, schools, sporting events, etc., personnel, which may include people generally, move between different locations to accomplish certain tasks or goals. For example, in an office building, in the event of a fire, personnel may move from their office location to an exit location with the goal of evacuating the office building. In an airport environment, personnel, which may include employees and travelers generally, may move from an airport entry to a check-in terminal, to security, and then to their specified gate for boarding and/or assisting with the boarding of an aircraft.
