Hardware Support - Recommended EZ Belt Layouts
|
Layout: L3
Layout Type: Temporary Installation
Sensors Used: One 26' EZ Belt
Spacing: 4 Inches
Count Formats: Basic, Volume Only
Data Provided: Volume, Gap
Channels: 2 Channels, A to B, B to A
This layout is mainly used for recording traffic volumes on two lanes of traffic, where data must be recorded for
each individual lane.
Vehicles in the inner lane hit the A tube followed by the B tube, but their hits on the B tube are not counted since
they were immediately preceded by a hit on the A tube. Vehicles in the outer lane hit the B tube followed by the A
tube, but their hits on the A tube are not counted since they were immediately preceded by a hit on the B tube.
Layout: L5
Layout Type: Temporary Installation
Sensors Used: One 14' EZ Belt
Spacing: 4 Inches
Count Formats: Basic
Data Provided: Class, Speed, Gap,
Volume
Directions: 1 Direction, A to B
This layout is one of the most commonly used when data for speed or classification is needed. It is designed for
one lane of traffic.
Layout: L6
Layout Type: Temporary Installation
Sensors Used: One 26' EZ Belt
Spacing: 4 Inches
Count Formats: Basic
Data Provided: Class, Speed, Gap,
Volume
Directions: 2 Directions, A to B, B to A
This layout is one of the most commonly used when data for speed or classification is needed. It is designed for
typical two-lane roads with bi-directional traffic.
Vehicles in the inside lane hit the A tune first, then the B tube and are recorded as Direction 1. Vehicles in the
outside lane hit the B tube first, then the A tube and are recorded as Direction 2.
With this layout, you sacrifice some accuracy for the convenience of only having to use one TRAX to record two
lanes of data. For greater accuracy, record each lane separately using an L5 layout, if the road location allows a
TRAX to be installed on each side of the road.
Layout: L9
Layout Type: Temporary Installation
Sensors Used: Two 26' EZ Belts
Spacing: 4 inches
Count Formats: Basic, Volume Only
Data provided: Volume, Gap
Channels: 4 Channels, A to B, B to A,
C to D, D to C
This layout is mainly used for recording traffic volumes and is essentially the same as the L3 layout, but with the
addition of a second EZ Belt for additional lanes.
This layout is ideal for recording traffic volume on four-lane divided highways where the TRAX can be installed in
the median.
Layout: L10
Layout Type: Temporary Installation
Sensors Used: Two 14' EZ Belts
Spacing: 4 Inches
Count Formats: Basic
Data Provided: Class, Speed, Gap,
Volume
Directions: 2 Directions, A to B, C to D
This layout is used when data for speed or classification is needed, and is essentially the same as the L5 layout,
but with the addition of another EZ Belt for additional lanes.
This layout is ideal for recording class or speed data on divided highways, where the TRAX can be installed in
the median.
