ASF - 2002 annual report - Vinci

Maintaining the road surfaces
to give the motorway a comfortable
line with good road
holding.
The increase of traffic accelerates
the normal wear and tear of the surfaces.
At the time of repair work of
the surface course, the Group’s
teams take the greatest care to
select the surfacing that is the best
suited to the traffic density, the climate,
etc.: surfacing with a high
level road holding resin base, draining
surfacing avoiding projections
of water behind vehicles in rainy
weather.
In order to minimise the disturbance
caused by the work, ASF has a
computer system of planning and
management of construction sites.
In 2002, close to 300 km were handled
over the whole of the ASF network.
Generally carried out in successive
sections of 4 to 6 km with a
switch from one road direction to
the other, and by night for the
Comfort and Service Areas
busiest sections, the public was
kept constantly informed of this
work.
Regularly sounding out the
civil engineering works to
anticipate repairs
ASF has equipped itself with a
powerful geographical information
computer system, called SIGAL,
which provides comprehensive
information about the state of the
structures in order to ensure their
optimal management. This system,
which can also communicate with
other databases about the civil
engineering works, the roadways or
the operating equipment, optimizes
the programming of maintenance
operations.
Extending the area of coverage
of Radio Trafic to inform all
customers, wherever they may
be on the network
In 2002, Radio Trafic undertook the
conquest of the Centre of France.
This extension corresponds to the
launch of the third phase: the
new listening areas will represent
around 950 extra kilometres. They
will be in addition to the 1,600 km
currently covered (east and west
areas). They are scheduled to be
brought into service gradually from
end 2002 to 2004.
Radio Trafic is now principally, and
soon will be totally, broadcast by
the Sesat satellite (Eutelsat group).
