Collision Awareness System
The MineAlert™ Collision Awareness System is an early-warning system that alerts equipment operators to potential collisions with other CAS-equipped vehicles, helping to improve operator awareness and reduce vehicle-to-vehicle collisions. Predictive algorithms analyze the location, speed, and trajectory of all vehicles in the monitored vicinity, generating warnings and alarms only when hazardous or potentially hazardous conditions exist.
Unlike other collision awareness systems on the market, Modular focuses on minimizing false alarms (nuisance alarms) to provide operators with critical decision-making safety information only when it matters.
The Collision Awareness System:
- Determines a vehicle's collision risk based on travel speed, instantaneous direction, predicted path, and other factors
- Alerts operators about potential dangers without delay, allowing them to take corrective actions to prevent a collision
- Minimizes false alarms with advanced predictive-path and pattern recognition algorithms
- Addresses the most common vehicle-to-vehicle collision scenarios, including Forward collisions, Take-Off collisions, Head-On collisions, Speed Limit violations, Blind-spots, Overtaking, Intersections, and more
Integration with DISPATCH® Fleet Management System (FMS)
The Collision Awareness System is available as a stand-alone version, or it can be integrated with the DISPATCH FMS for additional functionality, including:
- Event logging
- Exceptions and notifications
- System health status
- Intelligent algorithms to minimize nuisance alarms
- Simple, intuitive in-cab display
- Rugged design, suitable for harsh mining environments
- Immediate Vehicle-to-Vehicle communication
- Configurable Alarm Zones
- No radio or IT infrastructure required
- 360-degree detection
- Forward-looking platform
- Available as a stand-alone system, or integrated with DISPATCH FMS
Intelligent Path Prediction
The MineAlert Collision Awareness System utilizes vehicle velocity, acceleration, and yaw rate to intelligently predict a vehicle’s path. The technology accounts for two vehicles that may approach each other without actually posing a collision risk, helping to minimize false alarms that can desensitize operators to true risks. Path history serves as a “breadcrumb trail” to predict where a vehicle will go, based on its historical movements and patterns.
The Collision Awareness System predicts and address the most common vehicle-to-vehicle collision scenarios, including Forward collisions, Head-On collisions, Take-Off, Speed Limit violations, Overtaking, Blind-spots, Intersections, and more.

Forward Collision Warning (Front-to-Rear):
The MineAlert Collision Awareness System is fully configurable to adapt to specific mine needs, including speed, fleets, and different situations. Typical configuration parameters include speed thresholds, distances, vehicle types, and warning zones.
GNSS Antennas: Global Navigation Satellite Systems (GNSS) antennas are used to determine speed, direction of travel, and trajectory history. Dual GNSS antennas are mounted on the outside of CAS-enabled equipment, providing superior heading accuracy at all times, even on startup when equipment has not yet moved. The dual GNSS antennas also enable directional alarms, such as the Take-off Warning and Intersection Movement Assist, even when the equipment is stationary.
DSRC Antennas: a direct, dedicated vehicle-to-vehicle radio channel handles communication between enabled vehicles via dedicated short-range communications (DSRC) antennas, mounted on the outside of the equipment. DSRC antennas:
- Eliminate need for communication infrastructure
- Can work in most mine settings
- Provide 360-degree detection to avoid radio dead spots on heavy equipment
- Are low latency – direct, two-way communication between vehicles facilitates extremely rapid transmission
Collision Risk Analysis
CAS-Hub: Intelligent path-prediction algorithms determine the risk of collision for specific scenarios, allowing you to leverage scenario-based warnings. The system loaded in each vehicle determines unsafe situations around that vehicle, and then alerts the driver to those potential risks. Scenarios are expandable and adaptable without having to change hardware.
In-cab Mobile Display: A dedicated mobile display warns the operator if an algorithm detects elevated risk. Extensive scenario-risk filtering drastically reduces false alarms, and a simple interface provides visual and audio warnings coupled with easy-to-read symbols.
DSRC Standards: The Modular approach is based on standards, technology, and algorithms developed for the automotive market within the last 15 years. The MineAlert Collision Awareness System has also undergone several years of intensive field trials using these same standards.
