Operating principle of the LMS Width
The beam of the
LMS Width
is emitted perpendicular to the road surface. Depending on
the mounting situation, the LMS Width detects the side and top of the vehicle.
The recording process starts as soon as a vehicle is detected by the LMS Width. The
recording process stops when the LMS Width detects the final point on the vehicle. After
the vehicle has passed through, 2D cross-sections are generated and sent to the Traffic
Controller FPS.

Operating principle of the LMS Length
The beam of the gantry-mounted
LMS Length
is emitted along the direction of travel. It
detects the top, front, and tail of the vehicle. The data captured by the LMS Length are
used to calculate the length and speed of the vehicle.
