# Rio Tinto: Autonomous Haulage System for iron-ore operations

A central system can drive mine trucks on fixed routes while people supervise and manage exceptions remotely.

Function: Engineering design. Patterns: Exception-based operations; Autonomous with a backstop; Coordination compression. Evidence: reported.

Freshness: watch. Reviewed: 2026-08-23. Updated: 2026-08-22.
Watch status: verify the cited source and deployment condition before reusing this case.

Source quality: 1 primary; publication outcomes are reported.

## Before

1. **Truck operator** — Drives heavy haul truck along mine roads and intersections. (control: Operator judgment and mine traffic rules.)
2. **Dispatcher** — Coordinates vehicle assignments and traffic. (control: Site operations control.)

## After

1. **Autonomous haulage system** — Navigates trucks on predefined GPS courses using fleet position, speed, and direction data. (control: Supervisory system and central controller.)
2. **Central controller** — Monitors fleet flow and intervenes for exceptions. (control: Human operational authority and exclusion zones.)

## Decision rights

The system controls routine driving; central controllers authorize operations, manage traffic, and stop or recover vehicles.

## Exception path

Faults, obstacles, or route anomalies stop the vehicle and escalate to central control and field teams.

## Outcomes

- **Truck operating time and cost** (reported): Conventional human-driven haul trucks. → In 2018 each autonomous truck was estimated to operate 700 more hours on average with 15% lower costs.. Company estimate; mine mix and operating context affect transferability.
- **Driver road exposure removed by automation** (reported): Drivers worked around heavy machinery for routine haulage. → Routine truck operators were removed from the autonomous driving task.. Overall injury rates are not attributed solely to haulage automation.

## Executive lesson

The role redesign is fleet supervision and exception recovery, not simply replacing a driver with software.

## Anti-pattern

Inferring whole-site safety improvement from removal of one exposure pathway.

## Questions for leaders

- What hazards move to controllers and maintainers?
- What is the safe degraded mode?
- Which productivity figures are independently audited?
