How RoadDefender Works

Edge-first work zone safety in seconds

RoadDefender turns traffic risk into immediate wearable worker alerts through on-site edge processing, with cloud visibility available when needed.

  1. Detect risk

    Radar and camera sensors continuously monitor approaching vehicles and movement at the work zone boundary.

  2. Decide on-site

    The edge unit evaluates risk locally in real time — no cloud round-trip required for critical decisions.

  3. Alert workers immediately

    Workers receive multi-sensory wearable alerts within milliseconds of a risk threshold being crossed.

What happens in real time

Work zone intrusion detection: How the system works

Sense → Decide → Alert

Every alert follows a local Sense → Decide → Alert path built for speed, with optional cloud visibility that never delays delivery.

Sense

Radar and camera sensors continuously monitor approaching vehicles and movement around the work zone. Detection stays local and uninterrupted.

Decide on-site (edge processing)

Critical decisions are made locally in real time. Edge logic evaluates intrusion risk and urgency without waiting on remote services.

Alert

When thresholds are crossed, workers receive immediate wearable worker alerts designed to cut through noise and visual distraction.

Optional cloud visibility

Aggregated events can sync to cloud for multi-site visibility and traceability. Cloud services are optional and never delay alert delivery.

Key takeaway: Alerts always follow Sense → Decide → Alert; cloud visibility is optional and never delays alerts.

Hardware & Deployment Options

Response reliability

Why Edge-first work zone safety matters

Built for time‑critical decision making

In active work zones, milliseconds matter. Edge processing keeps detection and decisions at the roadside so alerts remain immediate even when network conditions change.

Lower latency

Critical alerts are processed directly on site. By evaluating risk locally, RoadDefender reduces dependency on network round‑trips and minimizes delay between detection and alert delivery.

Works without connectivity

Alerts do not depend on continuous network availability. If connectivity is degraded or unavailable, local detection and alerting continue uninterrupted.

More resilient in real‑world conditions

Work zones are noisy, visually complex, and unpredictable. Edge processing allows the system to operate reliably where centralized or cloud‑dependent systems may struggle to respond consistently.

Key takeaway: Edge processing improves response speed and resilience in noisy, changing work-zone conditions.

Who Gets What: Outputs at Every Level

RoadDefender delivers the right information to the right people at the right time.

Workers — Immediate awareness

Outcome: Workers get direct, personal alerts the moment risk thresholds are crossed.

  • Immediate multi‑sensory alerts on Samsung wearables.
  • Direct individual alerting inside the active work zone.
  • Local delivery path with no cloud dependency.

Supervisors — Local visibility

Outcome: Supervisors get live local context to make immediate work-zone decisions.

  • Current site status and active alert visibility.
  • Decision support to pause, adjust, or resume work quickly.
  • Real-time view focused on what is happening now.

Operations teams — Optional program‑level visibility

Outcome: Operations teams get optional cross-site visibility for oversight and review.

  • Optional cloud aggregation across crews and sites.
  • Traceability for event review and program oversight.
  • On-demand visibility rather than scheduled reporting.

Key takeaway: Workers get immediate alerts, supervisors get live local context, and operations teams get optional cloud-level oversight.

Operational visibility — on demand

From Edge Alerts to a Live Safety Dashboard

Edge units issue alerts locally and immediately, while event data can optionally flow to the Safety Dashboard for operational visibility.

Alerting stays on-device regardless of network state; dashboard visibility is asynchronous and non-blocking.

Conceptual illustration of the live Safety Dashboard showing operational visibility across deployed units

Edge units execute local alerts independently of dashboard connectivity. The dashboard provides centralized visibility into outcomes—not control over how alerts are issued.

What the Safety Dashboard Provides

Operational Activity View

  • Live view of deployed units, active alerts, and recent events.
  • Supports deployment decisions without affecting edge alert execution.

Event Traceability

  • Structured, time‑stamped records of alerts and zone events.
  • Supports post-incident review and operational accountability.

System Health Monitoring

  • Unit-level connectivity and health status across deployments.
  • Supports readiness planning without interfering with edge logic.

Program‑Level Capability

Multi‑Site Program Visibility

  • Consolidated program view across multiple crews and sites.
  • Fleet-level oversight while each unit keeps autonomous alerting.

Key takeaway: The Safety Dashboard is a visibility layer only; local edge alerting remains authoritative for time‑critical outputs.

Dashboard data reflects events as recorded at the edge. Visibility is available on demand; RoadDefender does not rely on scheduled or regulatory reporting.
