Smart Traffic Lights

Why is traffic management important?

• a) It ensures smooth traffic flow and saves fuel and time of commuters.

• b) It guarantees the emotional wellbeing of pedestrians only.

• it helps in building more roads and highways.

• It has no significant benefits.

What is traditional traffic management?

• a) Smart traffic signal controlling traffic flow.

• Traffic wardens manually controlling the traffic.

• Pedestrians controlling the traffic.

• Automatic traffic signal controlling traffic flow.

What is a Smart Traffic Signal?

• A signal that automatically alters the traffic light timings depending on traffic density.

• A signal that is controlled by pedestrians.

• A signal that requires manual adjustment.

• A signal that is controlled by traffic wardens.

What materials are required to design Smart Traffic Lights?

• Arduino UNO, IR sensor module, LED module, mini breadboard, and jumper wires.

• LDR sensor module, LED module, paper tape, and scissors.

• Screwdriver, LDR sensor module, and jumper wires.

• Only the Arduino UNO is required.

What is an LDR sensor module?

• b) A module that is sensitive to sound.

• A module that is sensitive to temperature

• a) A module that is sensitive to light.

• d) A module that is sensitive to touch.

What is the output of the LDR sensor module when there is light?

• LOW (0 Volts)

• The module becomes damaged

• The module output is not affected

• HIGH (5 Volts)

What happens when the light intensity decreases below the set threshold of the LDR sensor module?

• The sensor becomes damaged.

• The sensor stops working.

• The sensor is triggered.

• he sensor produces a false output.

What are the necessary assumptions to be made for the project?

• Developing Smart Traffic Signals.

• Both A and B.

• Developing a system that lights up the LED (R,Y,G) module like a real-life traffic light.

• None of the above.

What is the first stage in the Planning phase?

• Ideate/Design.

• Empathize & Define.

• Implementation/Test.

• Iterate.

What is the definition of a “sensor”?

• A device that responds to sound only.

• A device that responds to light only.

• A device that responds to light, heat, or pressure and converts it into a measurable signal.

• A device that responds to temperature only.
