Which type of detection device is typically installed over or next to the highway?

• A. Intrusive
• B. Non intrusive
• C. Mobile
• D. Dynamic

Answer: (B)

Non-intrusive detection devices are designed to gather data without requiring physical installation or modification to the roadway itself. This type of device often includes technologies such as radar, video cameras, and inductive loops that can monitor traffic flow and conditions from a distance, making it ideal for positioning over or next to highways. These systems can collect valuable information about traffic volume, speed, and vehicle classification while minimizing disruption to the road surface and ongoing traffic. The non-intrusive nature ensures easy installation and maintenance, which is particularly beneficial for highway environments where traffic conditions need to be carefully managed.
