1.3.2 Express Wash Applications
Express Exterior sites should be designed to provide 9 ft. wide traffic lanes at the
Portals. The traffic control (or barrier) gate should be located approximately 10 ft. from
the center of the Portal and an underground vehicle detection loop is required under
the gate arm. In some cases, it may be desirable to install a 2
nd
loop between the
gate and tunnel entrance (referred to as the merge loop) to properly manage the
vehicle queue.
If the Unitec ReachFree ID (RFID) option is included, the RF Antenna should be
located adjacent to the Portal. Figure 3 provides guidelines for the design of an
Express lane with the Portal, gate and RFID (antenna) option. Refer to the
installation instructions provided with the gate and RFID option for guidance in
installing these devices.
