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.

| 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.
