Opticom™ GPS Priority Control System
What Is It• 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.
Opticom™ GPS Priority Control System
Vehicle Equipment• Radio/GPS unit
• Radio/GPS antenna
• Vehicle Control Unit
Opticom™ GPS Priority Control System
Intersection Equipment• Radio/GPS Unit • Phase Selector• Card Rack
Opticom™ GPS Priority Control System
How Does it Work• Vehicle radio obtains position, speed, heading
and turn signal status from GPS satellites
• Vehicle radio transmits this information and ID to intersection
• Intersection radio receives information and sends a priority request to the equipment in the traffic controller cabinet
• The traffic controllers is programmed to provide a green light for the approaching vehicle
• Activity is logged

How Does it Work
Opticom™ GPS Priority Control System
How Does it Work• First-come, first-served
– Whichever vehicle is in range first will be granted the priority request
– Second vehicle will be serviced when the first clears the intersection
• Multiple vehicles traveling in the same direction will all be granted the green light
– Will hold for six seconds after vehicle enters the intersection
• Drive as though the system is not there
• Drive the green lights
Opticom™ GPS Priority Control System
Turn Signal Use• Always use your turn signal
• System will relay your request around the corner to the next equipped intersection but only if turn signal is used
• Activate turn signal as far in advance as possible
Opticom™ GPS Priority Control System
Vehicle transmits location,speed, heading, IDinformation and turn
signal status to OpticomGPS equippedintersection A
Intersection A relays priorityrequest to the next OpticomGPS equipped intersection(B) in the direction of the
approaching vehicle's turnsignal

Opticom™ GPS Priority Control System
How Far Back will it Activate• Opticom GPS has a 2,500 ft minimum range
• Most intersections set to activate at:
– 30 seconds OR 1000 ft• Whichever threshold is achieved first
• Actual time to display green will vary based on point in controller cycle when green is requested– Should always see green before entering intersection
• Will go all red prior to displaying green– May not see
Opticom™ GPS Priority Control System
Intersection Signal Timings• Example: A signal can have a 24-second delay
before turning green– 6 seconds – Minimum green– 12 second – Pedestrian clearance – 4 seconds – Minimum yellow– 2 seconds – All red clearance– Equals a 24 second delay

How Will Other Drivers React
• If light just went red, drivers may not expect it to turn green so quickly and hesitate before moving again
• Other emergency drivers may assume they have control
• Drive defensively
Opticom™ GPS Priority Control System
Activation Lights
• Activation lights are intended to let you know that the system has been activated
• Confirmation lights are blue globes or the old lights• Confirmation lights will illuminate during
preemption– You may not see them
• Another vehicle may have activated the system and may get the green before you
• Drive the signal lights not the activation lights!

Troubleshooting• Is problem present in all vehicles or only certain
vehicles?
– If no vehicles activate a specific intersection, problem is likely in the intersection
• Is problem present at all intersections?
– If specific vehicle will not activate any intersection, problem is likely in vehicle
• Notify BC Aston for vehicle problems
• Notify the 40hr BC for intersection problems
