Traffic Preemption System

DOES YOUR COMMUNITY NEED EMERGENCY VEHICLE PREEMPTION?

1Traffic, stoplights, and other emergency vehicles traveling from other directions all present obstacles for emergency personnel, and cost precious time in an emergency situation where seconds of response time can be the difference between life and death.

The solution to these problems is preemption, and until now, these systems have been expensive and complex to implement for municipalities. Additionally, they have never addressed the issue of Collision Avoidance for emergency vehicles. This is where the Eliminator™ from Collision Control Communications comes in.

The Eliminator™ is a state of the art traffic signal preemption system that overcomes the shortcomings inherent in currently available technologies. Unlike infrared/optical preemption systems, the Eliminator’s capabilities are not limited to line of sight. Preemption is easily triggered irrespective of visual obstructions such as semi-trailers, buses, bridges or overpasses; it works equally well where visibility is reduced by heavy fog, snow, rain or blowing sand/dust.

While GPS preemption systems have overcome many of these drawbacks, the Eliminator™ takes the technology one step further by including an Inertial Measurement Unit, which allows position and track of each emergency vehicle to be calculated in real time without the presence of a GPS signal. This technology allows the Eliminator™ to work where other systems fall short due to their reliance on GPS triangulation for position, and allows us to offer the lifesaving advantage of collision avoidance.

FACTORS TO CONSIDER WHEN CHOOSING A PREEMPTION SYSTEM

  • System and Equipment Cost
  • Cost Savings
  • Benefits of Preemption
  • Lives Saved with Quicker Response Times
  • Improvement of your City’s ISO Insurance Classifications, Reducing Insurance Premiums
  • Improved Safety for Emergency Vehicle Personnel
  • Reduction in Collisions Between Emergency and Passenger Vehicles
  • Reliability of System
  • Installation Cost
  • Maintenance Costs

EMERGENCY VEHICLE PREEMPTION CAN PAY FOR ITSELF

Cost savings analyses conducted in cities already using traffic signal preemption have demonstrated that preemption pays for itself in a relatively short period of time.

In the city of Plano, Texas, for example, preemption decreased response times and allowed Plano’s fire stations to serve 7.5 square miles per station instead of the anticipated 5.6 square miles1. This allows for a greater service area for each station, reducing facility and staff costs.

The benefit to the city is that it is currently operating 10 stations compared to the 13 that had been forecast, resulting in a capital cost savings of approximately $9 million and an annual operating cost savings of approximately $7.5 million1.

The return on investment of the Eliminator™ is the highest in the industry. Minimal hardware requirements and streamlined installation, coupled with the potential life, equipment and cost savings, make the Eliminator™ the best value in preemption. The addition of Collision Avoidance offers something truly priceless – peace of mind for your emergency personnel.

  • Backup Inertial Measurement Unit for when Satellite Triangulation is not available
  • Collision Avoidance warns equipped emergency vehicles of an impending collision
  • Collision Avoidance does not require a traffic signal – works even in rural areas via V2V communications protocol
  • Other preemption systems do not have this feature
  • Preempts traffic signals:
  • - Under adverse weather conditions
    - Reliably in heavy fog/snow/rain/dust
    - Through obstructions: buildings, buses, vehicles, foliage, bridges
    - Around curves in the roadway
  • Does not require realignment after heavy winds
  • Provides 360° protection against collision with other emergency vehicles, even at unsignalized intersections
  • Visual confirmation in the vehicle of preemption status, overlaid on a map
  • System can pro-actively preempt upcoming additional intersections laterally based on the vehicle’s turn signal status

ADVANTAGES OF THE ELIMINATOR™ OVER OTHER GPS SYSTEMS

The Eliminator™ offers features and benefits above and beyond any other preemption system on the market. In fact, we think you will agree that feature for feature, there are no comparable products available on the market.

THE ELIMINATOR™ EASE OF USE

We’ve created the Eliminator™ to be easy to use and understand in an emergency vehicle setting. Our Graphical User Interface allows for easy use of the unit compared to LED based systems, as well as allowing for a greater level of awareness for the types of vehicles in your area. Following are a few different scenarios you may encounter, and how the Eliminator™ handles them.

TRAFFIC SIGNAL ELEMENTS

On Screen A you will see the three basic elements of the display. The GREEN Triangle represents an Intersection equipped with the Eliminator Traffic Signal Control System and Green color specifies that the Eliminator’s™ request for a Green light has been acknowledged by the Traffic Signal Controller.

If a Preemption request cannot be granted by the Eliminator™ due to an overriding priority of another vehicle then a RED Circle will display.

If an equipped intersection does not have an active preemption request then the square will be devoid of color.

Screen B
Screen B

TRAFFIC SIGNAL ELEMENTS

Screen B displays three vehicles and one intersection. Remembering that this display is for the vehicle represented by the IBeam, the traffic signal is Red and there is a Fire Vehicle going through that intersection. Although each city can customize their priority settings, typically a Fire Vehicle gets highest priority as they are the most difficult to stop/slow down. Just below the Fire Vehicle is a Police Vehicle. Since the Police vehicle is going the same direction as we are (we being the IBeam), there is no alert for an impending collision. However, you do have an impending collision with the Fire Vehicle and therefore the IBeam and the Fire Vehicle are both highlighted with a Red Circle. There is also a 9s letting you know the ETA of 9 Seconds to the Fire Vehicle.


Screen C

SCENARIO #1

In this scenario on Screen C you have an impending collision with a vehicle that is off the screen and a Police Vehicle behind you. Vehicles behind you are never considered impending collisions.

You still get a 4s indicator letting you know the ETA to the impending collision.

You can also use the Pan or Zoom buttons (Right Menu) to bring the “off screen” vehicle into the view.

Additionally, you can use the Center button to quickly reset the map back to the default position.


Screen D

SCENARIO #2

In this scenario on Screen D you see Pan functionality. Notice the PAN button is grayed letting you know you are in PAN mode. Additionally notice that your vehicle is no longer aligned in the middle from left to right. You can use the four directional buttons below the PAN button to move the screen. You can also use the ZOOM functionality in PAN or POSITION (POS) mode.

Finally, on Screen E you can see the result of choosing POS and moving the slider down, it moves your vehicle position to the bottom of the screen and allows you to see more of the map in front of you.

ADMIN/TECH SCREENS

We’ve included a full series of admin and tech screens in the Eliminator™ that allow you to easily customize certain parameters, easily check vehicle status and verify a proper installation.

PIN Settings

PIN SCREEN

The Eliminator™ has a very robust set of “Admin” and “Tech” screens that are password protected. This allows city technicians and us to have quick easy access to features, and setup the system. To the left you will see the screen to enter your PIN code to gain access to these screens.


Device Configuration

DEVICE CONFIGURATION

To the left you will see the “Admin” screen that indicates the settings for the “Collision Avoidance Trigger Distance” in feet, and the “Collision Avoidance Trigger Window” in seconds. These can be customized according to the city’s preference.


Collision Distance Setting

COLLISION DISTANCE SETTING

To the left is the “Admin” screen where you can set the “Collision Avoidance Trigger Distance” in feet. A similar screen allows you to set the “Collision Avoidance Trigger Window” in seconds.


Settings

To the left you will see the “Tech” screen that shows the system status of the vehicle hardware (light bar, turn signals, etc.). This screen verifies the operational status of each. It also greatly simplifies the installation process, and verifies that the wiring connections of each vehicle system (light bar, turn signals, etc.) are correctly done. If not, the installer can just tap the user interface to reverse polarity, instead of rewiring. This screen is also a great troubleshooting tool.
