6.6 Heavy Vehicle to other RF tagged Vehicles Collision
Avoidance Due to Driver Fatigue
General fatigue management: the Heavy Vehicle Display Unit can be programmed as a
fatigue-monitoring unit where periodic alarms need to be actioned within a specified
response time. All fatigue alarms and operator reactions are data logged (along with RF
tag detections) for compliance monitoring & provides a safety audit trail in the event of an
incident (drivers are less likely to breach procedures knowing that vigilance methods are
being monitored). The CAS system RF tag audible alarms also act to combat fatigue.
HV to HV haul road collision due to driver fatigue: HV approaching another HV
traveling on opposite side of haul road collides with the oncoming HV due to driver fatigue
and driver not being aware of approaching HV and / or not maintaining adequate
clearance. The AMT CAS-CAM/RF
®
system alerts both HV drivers to each other’s
presence (within a programmed detection range up to 200-300m with long-range RF
option) using both audible & visual alarms.
A new extension to the CAS-CAM/RF
®
technology is a Guidance Laser System (CAS-
GLS
®
). The CAS-GLS
®
is a new remote sensing technology fitted to surface mining road
haulage equipment (e.g. Haul Trucks) that will automatically detect the presence of the
edge of the road (windrow), calculate the distance from the side of the Haul Truck to the
start of the windrow and report to the driver when the vehicle is operating within nominated
corridors (too close to edge – normal – warning - danger) using both visual and audible
indicators. Visual indication of whether an approaching Haul Truck is within or outside of
the nominated corridors is also provided for the benefit of oncoming Haul Trucks.
The GLS assists in managing driver fatigue by alerting both the vehicle driver and
oncoming vehicle when the vehicle is not operating within specified safe corridors for both
passing and normal driving operations. This is particularly important when mines upgrade
to larger payload capacity vehicles resulting in wider vehicles operating within reduced
safe operating corridors on existing haul roads.
The GLS can be operated either stand-alone or integrated with the CAS-CAM/RF
®
Display
Unit in the driver’s cabin to provide a fully integrated Collision Avoidance System using a
combination of high quality colour cameras and active RFID tags with programmable
detection zones for automatic object detection.
6.7 Other Applications
There are numerous other Collision Avoidance Applications involving Heavy Vehicles (with
blind spots) interacting with other Heavy Vehicles, Light Vehicles, Stationary Objects,
Personnel and other Mobile Plant & Equipment.
Refer to Section 7.6 for typical surface mining Collision Scenarios and CAS Solutions.
