Hardware Support - Recommended Tube Lengths and Setup
Select the layout that you would like to view:
Layout: L8
Layout Type: Traditional Road Tubes
Sensors Used: 4 Road Tubes
Spacing: Two Feet
Count Formats: Basic, Volume Only
Data provided: Volume, Gap
Channels: 4 Channels, A, B-A, C, D-C
This layout is mainly used for recording traffic volumes and is essentially the same as the L2 layout, but with the addition of two more tubes for two
additional lanes.

This layout is ideal for recording traffic volume on four-lane divided highways where the TRAX can be installed in the median.

With this layout, you sacrifice some accuracy for the convenience of only having to use one TRAX to record four lanes of data. For greater accuracy,
record each lane separately using an
L4 layout, or each pair of lanes separately using an L2.
