Abstract
A remotely controlled, portable, automated flagman includes a shaft rotatably supported by a housing containing the drive mechanism and control electronics to selectively turn the shaft such that a "stop" or a "slow" sign is displayed at the option of a user. The user controls the display of the "stop" and "slow" signs by a remote control unit. A tripod or other type of support structure is attached to the housing so as to support the traffic control sign at the proper height above the ground. The automated flagman of the present invention can take the place of a human flagman with a handheld sign in zones where temporary traffic control is needed.
