Hexagon’s latest Vehicle Intervention System (VIS) is the first open-pit Level 9 solution to pass the University of Pretoria’s (UP) Collision Prevention System (CPS) Technology Readiness Level 4 (TRL4) test. This achievement means mine operators benefit from improved safety, regulatory compliance, and reduced accident risk, as VIS automatically intervenes when hazards are detected.
Originally introduced in 2017 as the first available Level 9 solution, the new VIS features enhanced performance aligned with Minerals Council South Africa requirements. Level 9 systems, according to EMESRT (Earth Moving Equipment Safety Round Table), provide automatic machine intervention if the operator fails to respond to potential collisions, offering the strongest safety protection.
UP conducts independent TRL4 tests of CPS and Collision Warning Devices (CxD) under strict conditions, validating their basic functionality before field deployment. TRL4 certification is vital for South Africa’s MOSH initiative, confirming reliable, repeatable technology performance.
The test specification ensures CxD and TMM (Trackless Mining Machine) solutions meet standards for detection, warning, intervention, ISO21815-2:2021 compatibility, log keeping, and self-diagnostics. VIS has undergone extensive testing since 2017, cementing its ability to automatically manage braking, speed, safe distances, and system failures—minimizing accidents and boosting operational efficiency.
Hexagon’s Mining Division President, Dave Goddard, emphasized the importance of independent validation for future-ready safety technologies and Hexagon’s commitment to zero harm and regulatory compliance.
