Work zone intrusion detection that buys crews usable seconds.

Highway construction exposure is continuous — not occasional.

Roadside construction and paving crews work metres from live traffic in fast-changing conditions—often with limited reaction time. This exposure persists for extended periods across production phases as lanes shift, equipment moves, and conditions evolve over time. Risk is shaped by speed, duration, fatigue, and unpredictability — not isolated moments.

Cones, signs, and procedures help manage flow, but they don't provide real-time warning when something breaches the zone.

RoadDefender adds an active safety layer inside the work zone through work zone intrusion detection and wearable worker alerts so crews can pause, step clear, or brace before contact occurs.

Layers of exposure

Risk builds through stacked conditions across the zone, so the protection strategy has to account for more than the perimeter.

  1. 01
    Live traffic external risk

    Unpredictable vehicle flow and behaviors.

  2. 02
    Buffer / control zone

    Barrier or buffer set by traffic-control plans.

  3. 03
    Active work zone crews + equipment

    Personnel remain exposed for shift duration.

  4. 04
    Production movement

    Paving, milling, and equipment repositioning.

Active protection inside the work zone

RoadDefender adds a real-time detection and alerting layer inside the zone, where crews need usable warning time rather than post-event awareness.

  • Monitors approaching traffic and internal movement as conditions evolve throughout the shift.
  • Delivers early warning directly through wearables so crews can pause, step clear, or brace sooner.
  • Supports existing traffic-control plans with continuous awareness inside the work zone.

RoadDefender complements existing traffic control plans and training. It does not replace them.

Protection planning

Choose Your Level of Protection

Choose your level of intrusion protection—designed for highway construction and paving operations of any scale. Four protection levels help match coverage to crew size, exposure, and program scope.

Compare Protection Levels

Operational comparison. Each row answers a practical job‑site question to help identify the right level for a specific crew or program.

Swipe horizontally to compare all protection levels.

Single‑Operator Crew Work Zone (ASL Flagship) Multi‑Site (Enterprise)
Who gets alerted when a vehicle enters the area? One exposed worker Crew members Everyone in the work zone Crews across multiple sites
Does it detect dangerous vehicle behavior? — — Starts here (AI‑based) Included across sites
Who can see what happened after an event? Basic awareness Supervisor view Jobsite view Company‑wide view
What size operation does this level support? Lone worker or inspector Small paving crew Active highway work zone Multiple projects or regions
Is there centralized program oversight? — — — Yes — program‑level oversight

— indicates the capability is not provided at this level.

Frequently Asked Questions

Yes. RoadDefender is built for dynamic environments. Detection and alerting logic are evaluated locally at the edge and can align with changes in lane configuration, work‑zone boundaries, and crew positioning as conditions evolve throughout a shift.

Alerts are generated when approaching vehicles exhibit behavior that elevates risk to the work zone, such as unsafe approach speed or unexpected movement toward protected areas. At higher protection levels, additional inputs—including proximity‑based thresholds and behavior triggers—are used to address more complex intrusion scenarios.

Yes. RoadDefender supports a wide range of construction timelines, from short‑duration paving and maintenance work to longer‑term highway projects. Deployment approach and protection level are matched to project duration, exposure, and site complexity—not tied to a fixed project type.

RoadDefender is designed to integrate into live construction environments with minimal disruption. Deployment options include vehicle or equipment mounting, fixed or temporary placements, and rapid setup configurations. During scoping, detection zones and alert behavior are aligned with active workflows rather than forcing operational changes.
