The accuracy of the length and speed measurements can be increased by using a second
LMS Length
. This should be mounted slightly further along the road from the other one in
the direction of travel. Additionally, the LMS Length detects the front of the vehicle that is
within the measuring range. This approach is particularly good for improving the accuracy
of measurements in stop-and-go traffic.
The additional 2D LiDAR sensor further along the road can be mounted on a post or
cantilever beam. It does not have to be mounted overhead.

A single 2D LiDAR sensor can also handle system functions for more than one lane at
once. In the example below, the LMS Width has been mounted centrally between two
lanes so that it can capture the profile of the vehicles in both of them.
