Abstract: There is described an electrical cabinet for a traffic signaling system. The electrical cabinet generally has a housing; an input encoder, the input encoder having input ports receiving input signals carrying states associated with input devices of the traffic signaling system, a serial encoding circuit serially encoding the states of the input signals into a headerless signal, the headerless signal beginning with a first time slot and ending with a last time slot temporally spaced apart from the first time slot, the time slots carrying the states of the input signals, and an output port; and a traffic light controller having a serial decoding circuit receiving the headerless signal and serially decoding the headerless signal to retrieve the states of the input signals carried by the time slots of the headerless signal, the traffic light controller controlling the traffic signaling system based on the retrieved states.

Abstract: The electronic cabinet for enclosing electronic components generally has a housing having a base and a cover being connected to one another a plurality of lateral walls, one of the plurality of lateral walls having a first opening; a lateral perforated plate being mounted to the housing and extending over the first opening, the lateral perforated plate having a plurality of perforations; and a protector plate being mounted to the housing and extending over the lateral perforated plate to cover the plurality of perforations of the lateral perforated plate, the protector plate defining at least one air inlet between the protector plate and the lateral perforated plate.

Abstract: A unit for pedestrian control of traffic lights operated by a traffic light controller, comprises a casing adapted to be mounted to a traffic light post, the casing having a bottom face carrying a window, and a photocell mounted in the casing for directing a beam through the window in a downward direction generally parallel to the post to which the casing is mounted. The photocell is responsive to the presence of a pedestrian's hand placed beneath the window in the beam. The photocell is adapted to be operatively connected to the traffic light controller to send a signal thereto when the presence of a pedestrian has been detected.
