TRAFFIC LIGHT CONTROLLER
I have implemented a traffic light controller for an intersection of 2 busy roads, A and B. The light is controlled based on the traffic sensed by the sensor (sensor output Ta and Tb) on each roads.
Traffic Light Controller has been implemented using Mealy FSM of 4 states. Binary Encoding has been used to describe the states.
State 1: A: Green B:Red
State 2: A:Yellow B:Red
State 3: A: Red B:Green
State 4:A:Red B:Yellow
Timer: A timing feature has been added to the normal traffic light controller. This has been implemented using binary counters (feature in CircuitVerse). The timer avoids single lane traffic flow for a prolonged period of time and thus distributes flow between the 2 roads.
Clock time period: 5 seconds
Timer Limit for changing flow: 30 seconds
Burst: To make the project realistic, a burst mode has been used. Here the inputs A and B are bursts of traffic flow.
Random burst outputs are generated and used.
Using the Square RGB led light, the signals are coloured.
Launch the simulator and experience project…
