Top 10 Questions for Traffic Control Technician Interview

1. What are the different types of traffic control devices and what is their purpose?

• Traffic signals: Control the flow of traffic at intersections and other locations where vehicles need to yield or stop.
• Signs: Provide information to drivers about speed limits, road conditions, and other important factors.
• Markings: Paint or other markings on the road surface that guide drivers and indicate the proper path to follow.
• Other devices: Such as speed bumps, rumble strips, and bollards, are used to slow down traffic or prevent vehicles from entering certain areas.

2. What are the different types of traffic control plans and when are they used?

Manual traffic control

• Used in situations where traffic is not heavy and can be managed by a single person.
• The traffic controller uses hand signals or flags to direct vehicles.

Fixed-time traffic control

• Used in situations where traffic is predictable and can be controlled using a predetermined timing sequence.
• Traffic signals are set to change at regular intervals.

Actuated traffic control

• Used in situations where traffic is unpredictable and needs to be controlled in real time.
• Traffic signals are equipped with sensors that detect vehicles and adjust the timing sequence accordingly.

3. What are the different methods used to detect and monitor traffic flow?

• Inductive loop detectors: Wire loops buried in the pavement that detect the presence of metal objects, such as vehicles.
• Video detection: Cameras that monitor traffic flow and can detect vehicles, pedestrians, and other objects.
• Radar detectors: Devices that emit radar waves and measure the reflected signals to detect the presence and speed of vehicles.
• Microwave detectors: Devices that emit microwave signals and measure the reflected signals to detect the presence and speed of vehicles.

4. What are the different methods used to control traffic flow?
