Abstract
A one-person remote control system for overriding pre-established control sequences of a traffic light, which control system is compatible with plug-in communications connectors conventionally provided with traffic light controllers. The remote control system comprises a stationary signal transfer unit which has a signal receiver and a plug-in connector for communicating with the traffic light controller, and a mobile control unit disposed to receive manual commands from the person providing overriding control, and a transmitter for transmitting manual overriding command signals to the stationary signal transfer unit.
