TRAFFIC CONTROL DEVICES, SYSTEMS, AND METHODS
A portable handheld traffic control device includes a lamp, a housing that encloses the lamp, and a handle. The handle attaches to a proximal (back) side of the housing and includes a control panel operable by a thumb of a hand grasping the handle. In a first (vehicle) mode, the lamp emits light on a distal (front) side of the housing in one of four colors: red, yellow, green, or white, when a respective button for the corresponding color is pressed. In a second (pedestrian) mode, pressing the red button causes the lamp to display a steady red upraised hand, pressing the yellow button causes the lamp to display a flashing red upraised hand, and pressing the green button causes the lamp to display a steady white walking person figure. A battery powers the lamp. The device includes a secondary display visible on the proximal (back) side of the device.
