ABSTRACT
T-junction traffic light controller is such a device that will play a significant role in controlling traffic at junctions, to ease the expected increased rush at such junctions and reduce to minimum disorderliness that may arise, as well as allowing the pedestrians a right of the way at intervals rather than being struck down when in a hurry to cross the roads. Such an electrical system with a touch of electronics that control the flow of traffic in a pre-determined sequential pattern at a junction, has its diagram comprising of different components. The power supply unit provides the control unit with specified voltage from primary source. The pulse generator consisting of a timer generates pulse for the system. The clock or counter moderates the signal that enters the decoding logic system. The display unit of each stand consists of led, the first is red in colour, the second is amber in colour and the last is green in colour.
