7 TYPICAL COLLISION AVOIDANCE SCENARIOS
7.1 General
Typical collision avoidance scenarios for an open-cut mine site include operation between
moving vehicles on haul roads, loading and dump sites, around high-wall and various
bench levels and around other mine site obstacles such as buildings, plant and equipment
etc.
A typical CAS-CAM/RF
®
system would be configured for front and rear and optional left &
right detection zones on all Heavy Vehicles, with fully programmable alarming for each
object type (based on distance, detection location, direction of travel and speed), and a
single detection zone on all Light Vehicles, Stationary Objects, Personnel Tags, Test
Stations and Mobile Plant & Equipment.
The system operation covers the following Heavy Vehicle – Light Vehicle and Heavy
Vehicle – Heavy Vehicle interaction scenarios (ranked from highest to lowest risk):
7.2 Collision Scenarios and Solutions
CAS Scenario Solutions 2005
Reversing HV
Parked
Reversing HV
Parked
Reversing HV receives audible & visual
alarm when within 'AT-RISK' object
programmed detection range. HV
automatically switches to Rear Camera for
blind spot vision on both reverse gear or
when 'AT-RISK' objects are detected at
the rear. 'AT-RISK' objects also receive
audible and visual alarms (no audible
alarm on parked HV).
HV to 'AT-RISK' objects alarming
is two-way. Different HV alarm
ranges possible for different 'AT-
RISK' object types (e.g. HV front,
HV rear, LV, SO, TS, PT) and HV
speed.

Parked
or
Parked
or
HV driving forward receives audible &
visual alarm when within 'AT-RISK' object
programmed detection range. HV
automatically switches to Front Camera
for blind spot vision on both forward gear
or when 'AT-RISK' objects are detected at
the front. 'AT-RISK' objects also receive
audible and visual alarms when the HV is
in gear.
HV to 'AT-RISK' objects alarming
is two-way. Different alarm ranges
for different 'AT-RISK' object types
(e.g. HV front, HV rear, LV, SO,
TS, PT) and HV speed. HV RF
units located on front / rear / right
& left sides for close range start-
up object detection. Personnel
Tag (PT) proto-typed only and
subject to customer requirements.
