Scenari
L’esercizio del rinnovamento
Il tasso di incidentalità globale in
autostrada del Brennero dal 2001
a oggi è sceso di oltre 30 punti.
Nel 2022 la Società ha conseguito
il dato record di 14,81, metà della
media nazionale ferma a 27,04

Il futuro della mobilità
è digitale. E sensori
e telecamere hanno
reso smart il mondo
dell’automotive.
Se nel corso degli ultimi vent’anni
Autostrada del Brennero ha
più che dimezzato il tasso di incidentalità
globale il merito è di
un’azione condotta a 360 gradi
dalla concessionaria per incrementare
la sicurezza dell’arteria
e dei viaggiatori, che passa da
investimenti costanti ed elevati
in manutenzioni alla programmazione
oculata dei lavori fino
alla scelta di materiali, come l’asfalto
fonoassorbente e i sicurvia
in Cor-ten. Nel tempo la curva
si è appiattita perché deve fare i
conti con una causa incomprimibile
degli incidenti, ossia il fattore
umano. Per poter incidere anche
su questo elemento del calcolo
la via da percorrere è quella della
guida autonoma, che rappresenta,
a tutti gli effetti, il futuro
della mobilità. Il settore dell’automotive
ha già abbracciato con convinzione la
sfida, producendo veicoli capaci di guidarsi quasi
da soli grazie a sensori (radar, telecamere, lidar)
sempre più sofisticati e precisi, i cui dati
vengono elaborati in tempo reale da una Intelligenza
Artificiale in grado di prendere decisioni
in scenari differenti. Ma le strade e le autostrade
a che punto sono? Perché infatti auto e camion
smart possano esprimere tutte le loro potenzialità
è necessario che le infrastrutture viarie siano
attrezzate con una tecnologia adeguata a dialogare
con loro.

THE ACCIDENT RATE ON THE BRENNER MOTORWAY HAS
FALLEN BY MORE THAN 30 POINTS SINCE 2001. IN 2022,
THE COMPANY ACHIEVED A RECORD FIGURE OF 14.81
POINTS, HALF THE NATIONAL AVERAGE OF 27.04
The merit for this is an all-round effort by the company
to increase the safety of the road and those using it by
means of constant high investment in maintenance, careful
planning of work and choice of materials, such as
sound-absorbing asphalt and Corten safety barriers.
Over time, the curve has flattened because it has to
cope with a cause of accidents which is very difficult
to reduce, namely the human factor. Impacting on this
element in the equation means self-driving cars which
is, to all intents and purposes, the future of transport.
The automotive sector has already taken up the gauntlet,
producing vehicles capable of virtually driving
themselves thanks to increasingly sophisticated and
precise sensors (radar, cameras, lidar) whose data are
processed in real time by Artificial Intelligence capable
of making decisions in diverse scenarios. But what
point are we at with roads and motorways? For smart
cars and trucks to reach their full potential, road infrastructure
must be equipped with appropriate technology
capable of communicating with them.
Autostrada del Brennero, the company managing the
314 kilometres of the A22, has been pursuing this for
years now, joining and leading numerous international
research projects in the field, including C-Roads Italy,
coordinated by the Italian Ministry of Infrastructure
and Transport (MIT) and co-funded by the European
Commission. Its third edition ended in December 2023
and saw Autobrennero implement and supplement the
work done with C-Roads Italy. From the outset, the
project aimed to study and then test C-ITS (Cooperative
Intelligent Transport Systems) under real traffic
conditions. It is a Copernican revolution in traffic management:
the one-to-one relationship between the traffic
control centre, called CAU (User Assistance Centre)
in the case of the A22, which sends information to variable
message signs, in particular, is gradually being
supplemented by a C-ITS infrastructure which enables
communication primarily between infrastructure and
vehicles (I2V), but also between vehicles and infrastructure
(V2I). The axis around which this important
transformation revolves is georeferencing. That
is, in contrast with the past, the information that vehicles
and roads send to one another is constantly updated
and geolocalised, with the entire road mapped in
real time. The expected positive effects are manifold:
knowing the speed vehicles on the road are travelling
at, traffic conditions at each point and the volume of
cars and trucks present at all times makes regulating
traffic flows and speeds, increasing motorway capacity,
reducing stop&go phenomena and consequently
lowering the road’s accident rates and emission impact
on the environment. In C-Roads Italy, Autostrada del
Brennero developed and implemented the entire basic
infrastructure underlying this, drawing up the specifications,
creating a C-ITS server and equipping the
