What is the most labor-intensive type of vehicle detection installed?

Inductive loop detection is considered the most labor-intensive type of vehicle detection due to the installation process involved. This method requires the physical cutting of the pavement to install loop wire coils into the road. Technicians must carefully create a rectangular or circular loop design and then connect the loop to the detection equipment, necessitating significant manual labor and attention to detail to ensure proper function.

Additionally, the need for precise installation and calibration means that technicians often spend substantial time onsite. Any mistakes in the process can lead to faults in detection or operational inefficiencies, which can further increase the labor involved due to the potential need for rework. The installation tasks frequently include digging, laying out the loops, sealing with asphalt, and making electrical connections, making it significantly more laborious compared to some other detection methods.

In contrast, options like video detection, radar detection, and infrared detection often involve less intensive physical labor since they use sensors that can be mounted more easily without extensive pavement work. Consequently, while all detection methods have their complexities, inductive loop detection stands out as the most labor-intensive.
