The ELiMiNATOR® Emergency Vehicle Preemption System

A GPS and 900 MHz radio-based EVP/TSP platform that gives first responders and transit fleets a clear, predictable path through key intersections—without pushing every decision through a cellular connection.

How the ELiMiNATOR® Works

The ELiMiNATOR® EVP System is built around two core components: an in-vehicle unit and a cabinet unit at the intersection. The vehicle unit combines GPS and an inertial measurement unit (IMU) to determine location, speed, and heading. That information, plus vehicle class and priority request, is transmitted multiple times per second over a licensed 900 MHz radio channel.

At the intersection, the cabinet unit receives these requests and communicates with the traffic signal controller. Each preemption request follows the rules your traffic team configures, so signals behave consistently from intersection to intersection and across entire corridors as you expand the system.

Key System Benefits

Agencies use the ELiMiNATOR® to improve response times, reduce intersection risk, and give crews a more predictable experience in the field. These cards highlight the core behaviors the system delivers on every equipped corridor.

Detects vehicles earlier

Detects equipped vehicles earlier as they approach high-risk intersections, giving the controller time to safely serve the priority movement.

Sequences safe green time

Requests and sequences green phases while protecting pedestrians and cross traffic according to your existing timing plans.

Creates predictable behavior

Creates predictable, repeatable behavior at every EVP-equipped intersection so drivers know what to expect.

Captures data for review

Captures event logs and performance data to support after-action review, reporting, and compliance with your agency’s policies.

How the ELiMiNATOR® Compares

When agencies evaluate EVP options, the decision often comes down to three families of systems: optical / infrared, GPS-based, and cellular / cloud-based. The tables below highlight how the ELiMiNATOR® platform compares to typical GPS and cellular-centric approaches.

The ELiMiNATOR® advantages vs other GPS systems

Concern ELiMiNATOR® Competitor
Collision avoidance (V2V and unsignalized intersections)
GPS + IMU backup (keeps working without GPS)
Touch-screen GUI (operator-friendly)
Easy installation; abuse-proof settings
Wireless management (laptop/cloud) + API
Cost is a fraction of other GPS systems
~13,500 ft radio range (~2.5–2.7 mi)
Transit/management integration options
“Intelligent Preemption” (time/day/route)
Abuse-proof to prevent non-emergency use

Advantages of the ELiMiNATOR® vs Cellular

Concern ELiMiNATOR® Cellular
Scalability for dense environments.
Can function in adverse weather or disaster scenarios where cellular may be compromised.
Does not incur recurring cellular data costs.
FHSS guarantees security of the network.
Does not rely on carrier infrastructure or cellular coverage.
Highly resistant to interference, multipath fading, and jamming.
Mesh-style network for inter-communication of all devices in real-time.
Lower latency and faster acquisition/confirmation.

Designed Around Real-World Traffic Conditions

The ELiMiNATOR® was designed around the realities of actual corridors: congested approaches, limited sightlines, distracted drivers, and intersections that don’t always have textbook geometry. Radios and GPS hardware were selected with those conditions in mind.

Because the system uses licensed-band 900 MHz radio for range and penetration, it can continue to function even in bad weather, during large-scale incidents, or when cellular networks are overloaded.

Integrates with Your Existing Infrastructure

Cabinet units are designed to integrate with your existing signal infrastructure and controller types. The system can coexist with many legacy optical or cellular-based systems, allowing agencies to migrate corridors one step at a time instead of all at once.

Event logs capture preemption activity and can be used to support training, performance review, and data-driven decision-making for your engineering staff and leadership teams.

Warranty & Lifecycle Support

Deploying EVP is a long-term investment. The ELiMiNATOR® platform is backed by standard 7-year warranty and automatically extended to 10 years with minimal maintenance agreement.

We work with agencies to align warranty coverage with their capital and maintenance planning, and we can provide a separate written warranty overview for procurement teams and legal review. For the most current terms, just reach out and we’ll share the latest documentation.
