2Description

This section provides a general description of the Opticom™ GPS system and a detailed description of the

intersection equipment.

Opticom GPS System

The Opticom GPS system assists authorized priority vehicles through signalized intersections by

providing temporary right-of-way through the use of common traffic controller functions.

The Opticom GPS system consists of the following matched components:

Vehicle Equipment Components

•Radio/GPS unit containing a GPS receiver and a 2.4 GHz transceiver

•Radio/GPS antenna

•Vehicle Control unit

Intersection Equipment Components

•A traffic pole mounted Radio/GPS unit containing a GPS receiver with antenna and a 2.4 GHz

transceiver with antenna (Model 1010)

•Or a Traffic Cabinet mounted Radio/GPS unit containing a GPS receiver and a 2.4 GHz transceiver

(Model 1012) with a Radio/GPS antenna (Model 1050)

•Phase Selector (Model 764)

•Card Rack/Input File (Model 760)

•Auxiliary Interface Panel (Model 768)

Operation Description

The vehicle equipment is mounted on the priority vehicle. Its GPS receiver acquires position information

from the constellation of GPS satellites. This information is used to compute the location, speed, and

heading of the vehicle. This information, along with a priority request, ID information and the state of

the vehicles turn signal, is broadcast using the 2.4 GHz transceiver.

The intersection equipment receives the radio transmission from the vehicle equipment. The intersection

equipment then compares the information being received from the vehicle to the parameters stored in the

intersection equipment’s memory. If the vehicle is heading toward the intersection in a predefined

approach corridor, is requesting preemption and has met all other programmed parameters, the

corresponding phase selector output is activated. This output is connected to the traffic controller

preemption input. When activated, the controller cycles to grant a green light to the requesting vehicle or

holds the green allowing the vehicle to pass through the intersection.

The card rack/input file provides the power and logic wiring for the phase selector, which plugs directly

into a slot in the unit.

The auxiliary interface panel provides additional connection for monitoring green phases and also provides

additional outputs.

Intersection Equipment Installation Instructions

Intersection Equipment Details

The Opticom™ GPS System intersection equipment has two styles of Radio/GPS units available.

The first is the Model 1010, which is a compact, weather-resistant, Radio/GPS unit containing a GPS receiver

with antenna and a 2.4 GHz transceiver with antenna. This model is typically mounted on a traffic pole near

the traffic cabinet.

The second is the Model 1012 Radio/GPS unit, which contains a GPS receiver, a 2.4 GHz transceiver and a

separate Radio/GPS antenna. This model is mounted in the traffic cabinet with the antenna mounted on the

roof of the cabinet.

Both models of the Radio/GPS unit are connected to a phase selector via an 11-conductor radio/GPS cable.

The phase selector can be installed directly into an input file of a traffic controller equipped with priority

phase selection software. The phase selector can also be installed directly into virtually any other traffic

controller equipped with priority phase selection inputs and related software.

When input file space is not available in the traffic cabinet, a card rack is required.

The phase selector processes the signal from the radio/GPS unit and activates outputs which are connected

to the preemption inputs on the traffic controller. There are four channel outputs accessible on the rear

connector of the phase selector and up to 12 additional channel outputs accessible on the front of the phase

selector.

Each channel output delivers a constant output for high priority activation, and a pulsed output for low

priority activation. A high priority signal received on a channel will override any low priority activation. In

certain modes of operation, outputs may be activated that are dependent on the state of the requesting

vehicle’s turn signal. Another mode provides separate outputs for high priority and low priority. The use of

an auxiliary interface panel is required to access these additional modes and outputs.

Figure 2-1 shows the intersection components including the phase selector, card rack, input file, auxiliary

interface panel, and the wiring harnesses and cables. The 9-pin harness connects the card rack to the traffic

controller. Various communication ports are available to connect the phase selector to a PC or to remote

communication equipment. Additional communication connections are available on the auxiliary interface

panel. The auxiliary interface panel cable connects the phase selector to the auxiliary interface panel. The

radio/GPS cable connects the phase selector to the intersection radio/GPS unit.

NOTE: Illustrations and connections to the traffic controller may not be exactly as shown or described in

this manual. Refer to the controller wiring diagram for correct terminal connections.

3Radio/GPS unit Installation

This section describes the installation of the radio/GPS unit. There are two models of the radio/GPS unit.

See section 3.2 for details on installing the Model 1012 Radio/GPS unit.

3.1 Model 1010 Radio/GPS unit mounting Location Considerations

Read and understand the following precautionary paragraphs before starting the installation.

•The Model 1010 radio/GPS unit should be mounted in a location that has an unobstructed view of all

approaches out to a distance of 2500 feet (762m).

•Blockage of approaches by things such as bridges, buildings, walkways, and trees should be avoided.

•The Model 1010 radio/GPS unit is usually mounted to the mast arm or span wire pole nearest the traffic

controller cabinet. If an appropriate mounting location on a mast arm or span wire pole is not available,

you can mount the unit to a span wire. Try to use a signal head or sign mount to minimize sway.

•The Model 1010 radio/GPS unit should be mounted level and as high as possible. Do not mount the

unit upside down.

•The Model 1010 radio/GPS unit should have an unobstructed view of at least 50% of the sky.

•The mounting location should be such that the cable run from the radio/GPS unit to the phase selector

(located in the traffic controller cabinet) is no more than 250 feet (76m).

•The radio/GPS cable may be run through conduit or attached to a messenger wire. The cable should

not be suspended unsupported.

•The Model 1010 radio/GPS unit should be oriented such that the cable retainer is facing an area from

which vehicles will NOT be approaching. See Figure 3-1.

•Do not paint the Model 1010 radio/GPS unit cover. Metals or metal oxides in the paint may interfere with

GPS reception and/or radio reception/transmission.

•Do not modify the radio/GPS unit circuitry. There are no user-serviceable parts inside.

IMPORTANT NOTE

Modifying the radio/GPS unit may seriously

damage the equipment and void the warranty.

Do not attempt to modify the radio/GPS

circuitry in any way. Modifying the radio and/or

antenna in any way may cause the radio to

violate FCC/IC requirements.

REMARQUE IMPORTANTE

La modification du système radio/GPS risque

d’endommager sérieusement le matériel et

d’annuler la garantie. Ne pas tenter de modifier

les circuits du système radio/GPS de quelque

façon que ce soit. En modifiant le système radio

et/ou l’antenne de quelque façon que ce soit, la

radio risque de ne plus répondre aux exigences

de la FCC/IC.
