well as the complexity of the algorithms,
is significant. If you look at EMESRT
scenarios, for example, one scenario
involves an LDV approaching an
intersection with a main road for haul
trucks. For level 7 controls, all you
need to do is alert both vehicles. For
level 8, the system would need to detect
two types of vehicles approaching the
intersection, identify which vehicle has
right of way (in this case the haul truck),
and then notify the LDV that it has to
stop. For level 9, it has to be able to stop
the LDV as well, so it’s extremely complex
to implement.”
At the end of the day, it is the quarry
owner or manager’s responsibility to
ensure that their sites have undergone
risk assessments and comply with the
legislation once the deadline arrives. But
without the cooperation of OEMs and
third-party suppliers, as well as sharing
information within the industry as to
what does and does not work, this task
will be significantly more difficult than it
perhaps needs to be. ■

there are over 40.
