Abstract

This invention relates to a backup controller (10) for a traffic light (30), the controller (10) comprising: a series of lights (20) for incorporation with the traffic light (30); a replicator, for replicating the particular lighting sequence programmed in the primary controller of the traffic light (30); connecting means (80) for connecting the replicator with the series of lights (20); a backup power source (60), for powering the backup controller (10) in the event of a power outage; and control means, for controlling a change between a sleep mode, in which the backup controller (10) is in a standby state and the primary controller is in operation, and an active mode, in which the primary controller is inoperative and the replicator actively replicates the operation of the primary controller. It also extends to a complimentary traffic flow management system (120) for the intelligent management of backup controllers (10) associated with a series of traffic lights (30).
