Question

In a plant, there is a part which behaves like a two-way traffic light. Identify the part of the plant and draw the neat diagram and write its functions.

Answer 1

The normal function of traffic lights requires more than slight control and coordination to ensure that traffic and pedestrians move as smoothly, and safely as possible. A variety of different control systems are used to accomplish this, ranging from simple clockwork mechanisms to sophisticated computerized control and coordination systems that self-adjust to minimize delay to people using the junction.
