ASF - 2002 annual report - Vinci

■ Experimenting with radar posts
to check speeds
12 of these perfectly visible posts
will be installed by the “Gendarmerie”,
on an experimental basis,
in areas that are particularly sensitive
to speeding. This experiment
will be accompanied by a vast communication
campaign so that people
know where these posts are
located and what the “rules of the
game” of the system are.
Tunnels
The upgrading of safety in tunnels
continued in 2002: renovation of
the camera surveillance in the
Tunnel de l’Arme and the Tunnel de
Ricard, modification of the speed
limits on the Nice by-pass, installation
of systems to close the accesses
to the Saint-Laurent-du-Var,
St-Augustin, St-Isidore and Nice-
Nord interchanges…
Safety of Customers and Personnel
The renovation of the centralised
technical management of the A8
tunnels was also completed.
Finally, a survey was carried out and
presented to the authorities
responsible for risk analysis in
connection with the transport of
hazardous materials in the A8
tunnels on the Nice by-pass.
ESCOTA creates the “Tunnel
Mission”: this entity is responsible
for conducting operations to
upgrade the safety of the ESCOTA
network tunnels. During the last
quarter of 2002, it signed some
dozen specific survey contracts
to establish programmes to improve
the Tunnel de Mirabeau and the
Tunnel de la Beaume (A51), the
Tunnel de Monaco (A500) and the
tunnels of the Nice/Roquebrune
and Roquebrune/Italian border
sections (A8).
Management and supervision
of the network: 24 hours a day
every day of the year
A considerable amount of road
supervision and management equipment
has been installed on the ASF
network: cameras, automatic data
capture systems, variable message
panels, automatic lane closure devices.
Thanks to the SAE (Système
d’Aide à l’Exploitation), the traffic of
each section is kept under continuous
surveillance in real time. If an
unexpected event occurs, the information
reaches the District PC and is
then coordinated by the Vedène and
Mandelieu Information Centres.
With the aim of improving the uninterrupted
flow of traffic, ASF has
undertaken a review for the enrichment
of its “Mistral” (electronic
means to monitor traffic on connecting
motorways) operating system
while ESCOTA is going to undertake
a new project called “Pastre” (to
improve traffic surveillance on the
ESCOTA network).
