Final answer:
The wire stuck in the pavement before tollbooth stations is called an induction loop. It is used to detect the presence of a vehicle as it approaches the tollbooth, allowing the gate to open automatically.
Step-by-step explanation:
The wire stuck in the pavement before tollbooth stations is called an induction loop. It is used to detect the presence of a vehicle as it approaches the tollbooth, allowing the gate to open automatically. When a car passes over the loop, it disturbs the magnetic field created by the loop, and this disturbance is detected by the tollbooth equipment.
The wire stuck in the pavement before tollbooth stations is called an induction loop. It is used to detect the presence of a vehicle as it approaches the tollbooth, allowing the gate to open automatically.
The induction loop serves as a form of technology used to automate the toll collection process and improve traffic flow at tollbooths. It helps to reduce congestion and ensure efficient operation of the toll plaza.
