A remote control portable traffic signaling device (10) and system (94) for controlling a flow of traffic. The remote control portable traffic signaling system (94) includes the portable signaling device (10) and a plurality of warning flashers (76). The portable signaling device (10) includes a remote control unit (42) and a signal head (11) having an LED display device (50) and a microprocessor (46). The remote control unit (42) transmits a control signal to be received by the microprocessor (46) for use in controlling a message communicated by the LED display device (50). A base unit (30) including a storage compartment for housing the power source (36) is connected to the signal head (11) for supplying power to the microprocessor (46) and LED display device (50) via a connection wire (38) extending through a pole (24) positioned therebetween. A device for adjustably connecting the pole (26, 27, 28, 29, 35, 64 and 65) between the signal head (11) and base unit (30) allows for height adjustment of the portable signaling device (10). A plurality of warning flashers (76) including a pair of high luminous LEDs (82) are positioned at a predetermined distance from the portable signaling device (10) to warn passersby of the presence of the portable signaling device (10).
