PART B PLANNING
9 APPLICATIONS
9.1 INTRODUCTION
The LR-2000 reader is especially designed for Automated Vehicle Identification (AVI). The chief variables that must be considered
in planning the readers and credentials for the system are –
• Lane characteristics • Reader location
• Vehicle types • Credential characteristics
The most important factors in planning a system are listed in Section 3.2. These must be considered carefully when laying out the plan
for the installation.
The following paragraphs describe particular applications and recommend reader location and tag type for each application.
9.2 SMALL VEHICLES ONLY
If the reader is beside the lane, mount the reader as close to the edge of the lane as possible without damage to the reader. Choose the
left side of the lane when possible, because this side is easier for the driver (in right-lane-driving countries) to judge the vehicle’s
location relative to the left edge of the lane. Mount the reader on an adjustable bracket at a height of about 7 feet (for small cars, 6 feet
may suffice). Attach or hold a UHF card or tag on the same side of the vehicle as the reader. Aim the reader at the tags when they are
at the “sweet spot” – about 10 to 15 feet direct measurement from reader to tag as the vehicle approaches the reader. See Figure 4.

If the reader is centered above the lane, as inside a parking structure, mount the reader on an adjustable bracket at the lowest height
that assures safe clearance between the reader and the highest vehicle. Hook a HT-UHF Hangtag over the inside
rear-view mirror’s stem, or attach a UHF card to the back of the mirror facing the reader, or adhere a WS-UHF Windshield Tag
to the upper center of the windshield, behind the mirror. Aim the reader at the tags when they are at the “sweet spot”. See Figure 5.

9.3 MIXED PASSENGER CARS, PICKUPS, VANS AND SUVs
This application is a variation of Section 9.2. The reader beside the lane should be at about 7 feet height; the reader above the lane
must be raised to clear the higher vehicles. Mount the tags and cards in small vehicles (sports cars) higher than in larger vehicles
(SUVs). This places the tags and cards for all vehicles at about the same position relative to the reader. See Figure 4 and Figure 5.
