Smart traffic. Local control.
No cell signal required.

What Is Smart City Traffic Technology?

Smart City traffic technology is about signals, sensors, vehicles, and software working together to move people more safely and efficiently. Connected intersections share information, adapt to real-time conditions, and give priority to the vehicles that matter most—fire, EMS, police, transit, public works, and school fleets.

The ELiMiNATOR^® fits directly into that vision as a smart, connected device in the cabinet and in the vehicle. It uses a Zigbee-compliant mesh network in combination with GPS and 900 MHz radio to exchange information between intersections and vehicles in real time, without forcing every signal through the public cellular network.

• Smart signals and controllers that adjust timing based on demand and priority.
• Connected vehicles and field devices that announce their presence and intent.
• Standards-based communications, including Zigbee-compliant mesh, to knit corridors together.
• Software and analytics tools that turn real-world data into safer, more efficient corridors.

How Smart City Traffic Systems Typically Work

Most Smart City platforms follow the same rhythm: Sense, Decide, and Act. Detectors, cameras, and connected vehicles report position, speed, and congestion. Local controllers and/or a traffic management center decide which movements get green next. Signals change phase and timing to move priority vehicles first and keep everyone safer.

The ELiMiNATOR^® plugs into this model as a trusted, local decision-maker. At the vehicle, an onboard ELiMiNATOR^® unit requests priority. At the intersection, the cabinet unit receives that request via direct communication over a secure, Zigbee-compliant 900 MHz mesh network. This allows the traffic controller to preempt the intersection at a precise distance—without the lag, jitter, or dependency of a cellular or cloud-only path.

• Sense: Intersections and vehicles detect approach, speed, and direction.
• Decide: Local logic at the cabinet weighs priorities and safety rules.
• Act: The controller serves the right movement and clears conflicting traffic.

Why No-Cell Matters for Critical Corridors

Many Smart City solutions depend on cellular or broadband for every interaction. That can add carrier fees, latency, jitter, and single points of failure—especially when traffic is heavy or a storm or outage hits.

With the ELiMiNATOR^®, your core safety functions do not depend on a remote cloud server. When a vehicle needs priority, the request is handled right at the intersection, according to your rules—even if cell coverage is weak, a wide-area network link is down, or a carrier is congested.

• Built on a widely adopted, standards-based protocol.
• Designed for low-power, resilient, multi-hop field networks.
• Lets intersections share information without relying on cellular.
• Can coexist with other Zigbee-based Smart City devices (lighting, sensors, etc.).

Smart Priority Without Giving Green to Everything

Emergency Vehicle Preemption (EVP) is one of the most powerful Smart City tools—as long as it’s applied thoughtfully. With the ELiMiNATOR^®, onboard units in fire and EMS vehicles automatically send a preemption request as they approach a corridor. Intersection units receive those requests and talk directly to the traffic controller over the Zigbee-compliant 900 MHz mesh.

Signal timing is adjusted according to your agency’s rules: minimum pedestrian clearance, rail or mainline priority, left-turn rules, and more. Drivers see predictable, consistent behavior at each intersection, which reduces the need for risky maneuvers and “hope for the best” decisions.

Transit, Freight, and Smart Corridors

The same platform that protects fire and EMS can also support transit signal priority, freight routes, and special-event plans. You can equip buses or key city vehicles with onboard units that request priority only where it makes sense, and only when needed.

Zigbee-compliant mesh networking and 900 MHz radio give you a standards-based way to coordinate signals along the corridor, while traffic engineering teams fine-tune green time, priority rules, and coordination plans.
