Abstract
Japan Highway Public Corporation (referred to below as JH) is
introducing a CCTV surveillance system in long tunnels and tunnels
in which traffic is heavy as part of its emergency tunnel equipment
on the expressways that it manages, and operation supervisors are
detecting accidents and fires occurring inside the tunnels from
control rooms located in operation offices.
At the same time, JH is reducing the number of control rooms and
advocating broadening the surveillance area of each control room
with the aim of providing more efficient maintenance of the various
types of equipment used.
Broadening the surveillance area will mean an increase in the
number of long tunnels that must be managed from each control room
and there are fears that the increased workload will exceed the
level of monitor surveillance able to be provided by the operation
supervisors.
Agaisnt this background, JH has been detecting irregular
movement of vehicles (vehicles traveling at low speed, stopping or
changing lanes) using image processing technology and has been
promoting research into automatic incident detection systems which
detect any irregular incidents occurring in tunnels.
In this paper, we will discuss the proposal of a standard
architecture for image processing systems which will enable
automatic incident detection systems to be introduced into any of
the diverse range of tunnels managed by JH, and we will also
discuss the measurements conducted using a prototype image
processor which was produced based on the proposed
architecture.
