In high-traffic, high-tonnage open pits, the final layer of protection provided by a vehicle intervention system can be the difference between a near miss and a serious incident. Hexagon VIS is the first and only open-pit Level 9 solution to pass the University of Pretoria\u2019s Collision Prevention System (CPS) Technology Readiness Level 4 (TRL4) test specification.<\/p><\/div>\n
What Level 9 intervention really means<\/strong><\/h2>\nUnder EMESRT\u2019s (Earth Moving Equipment Safety Round Table) nine-level framework for preventing vehicle interactions, controls progress from site-level design and procedures through advisory systems to full automatic intervention.<\/p>\n
Level 9 represents the highest level of control. At this stage, a system can automatically intervene to slow or stop a machine if the operator does not respond to a hazard.<\/p>\n
In practical terms, this means:<\/p>\n
\n- Automatically inhibiting propulsion<\/li>\n
- Applying retarder or service braking<\/li>\n
- Enforcing safe following distances<\/li>\n
- Managing ramp overspeed<\/li>\n
- Bringing a vehicle to a safe state in the event of system failure<\/li>\n<\/ul>\n
These capabilities are designed as a last resort, activating only when a Level 8 warning has not been addressed.<\/p>\n

VIS originally became the first Level 9 solution available to the market when introduced in 2017. Before launch, it underwent more than 10,000 hours of testing in a working mine, establishing a benchmark for open-pit intervention.<\/p><\/div>\n
Independent verification under real-world scrutiny<\/strong><\/h2>\nThe University of Pretoria conducts TRL4 verification testing for CPS and Collision Warning Devices in controlled laboratory and proving ground environments.<\/p>\n
These tests are designed to validate that systems can reliably detect and prevent collisions through scientific, quantifiable, and repeatable testing. The scope includes:<\/p>\n
\n- Independent assessment of detection and tracking<\/li>\n
- Early warning functionality<\/li>\n
- Control functions<\/li>\n
- Logging capabilities<\/li>\n
- ISO21815 compatibility<\/li>\n
- Fail-to-safe and self-diagnostics<\/li>\n<\/ul>\n
Passing TRL4 is a critical stage gate in South Africa\u2019s MOSH (Mining Industry Occupational Safety and Health) initiative. It ensures technologies demonstrate reliable, repeatable performance before full integration into live operations.<\/p>\n
For customers, this independent validation provides confidence that VIS has been objectively tested against one of the industry\u2019s most stringent specifications.<\/p>\n

Building on a proven foundation<\/strong><\/h2>\nVIS originally became the first Level 9 solution available to the market when introduced in 2017. Before launch, it underwent more than 10,000 hours of testing in a working mine, establishing a benchmark for open-pit intervention.<\/p>\n
The latest generation of VIS builds on that operational heritage with enhanced architecture and performance aligned to current Department of Mineral and Petroleum Resources, and Minerals Council South Africa requirements.<\/p>\n
This evolution reflects a broader shift in mining safety:<\/p>\n
\n- From reactive reporting to proactive prevention<\/li>\n
- From siloed warning systems to integrated safety platforms<\/li>\n
- From manual compliance to digitally verified assurance<\/li>\n<\/ul>\n
As Dave Goddard, President of Hexagon\u2019s Mining Division, noted, the TRL4 verification \u201cgives our customers confidence that our next-generation Level 9 intervention solution has been independently verified in a controlled environment before moving to integrated site testing\u201d.<\/p>\n

<\/p>\n
Safety as a foundation for the digital mine<\/strong><\/h2>\nWhile VIS is a safety system, its impact extends beyond collision prevention. Hexagon is focused on connecting physical reality and digital intelligence into a continuously evolving system. Every interaction with the ore body is an opportunity to reduce uncertainty and carry forward knowledge across the value chain.<\/p>\n
At the centre of this vision is a living digital twin of the mine, a real-time, time-aware representation spanning exploration, extraction, processing and closure.<\/p>\n
In this context, VIS contributes in three important ways:<\/p>\n
\n- Trusted intervention enables trusted autonomy
\n<\/strong>Autonomy depends on confidence in detection, decision-making, and actuation. Level 9 intervention demonstrates that machines can respond deterministically and safely when required, a foundational capability for autonomous and semi-autonomous operations.<\/li>\n- Logging turns events into insight
\n<\/strong><\/strong>TRL4 verification includes logging capabilities. These data streams do more than document compliance. They feed the digital twin, enriching operational context and supporting continuous improvement.<\/li>\n- Safety supports productivity and value
\n<\/strong>Mining moves from reacting to variability to mastering it when decisions are synchronised across geology, planning and execution. A safer pit is a more stable pit. Fewer incidents mean fewer disruptions, more predictable production and stronger economic outcomes.<\/li>\n<\/ol>\nIn short, safety is not separate from productivity. It is a prerequisite for it.<\/p>\n
From compliance to competitive advantage<\/strong><\/h2>\nAcross global mining jurisdictions, regulatory frameworks are tightening. In South Africa, alignment with the Minerals Council framework and MOSH stage gates is essential. But leading operations view compliance as a baseline, not the goal.<\/p>\n
A verified Level 9 system helps mines:<\/p>\n
\n- Demonstrate regulatory alignment<\/li>\n
- Reduce risk exposure<\/li>\n
- Strengthen workforce trust<\/li>\n
- Accelerate digital transformation initiatives<\/li>\n<\/ul>\n
Because VIS is designed to integrate within Hexagon\u2019s broader ecosystem, including Fleet Management Systems and connected analytics, it becomes part of a wider, OEM-agnostic, open-platform approach consistent with Hexagon\u2019s focus.<\/p>\n
Rather than operating as a standalone safeguard, it becomes a key ingredient in a connected safety and productivity architecture.<\/p>\n
Advancing toward zero harm<\/strong><\/h2>\nThe industry\u2019s aspiration for zero harm requires more than policies and procedures. It demands systems that are measurable, verifiable, and engineered to act when humans cannot.<\/p>\n
By becoming the only open-pit Level 9 solution to pass the University of Pretoria\u2019s TRL4 CPS test, Hexagon VIS has cleared a critical stage gate on the path to integrated field deployment. It reinforces Hexagon\u2019s long-standing commitment to safety as foundational to mining\u2019s future, and integral to the broader transformation from ore to value.<\/p>\n
