ASFiNAG has currently initiated
the process to install the equipment along Austria’s highways, this includes up
to 525 Siemens Mobility Road-Side
Units (RSU), as well as establishing a control center. The first
C-ITS services that will provide hazard warning services are expected to go
into operation within the next 16 months. With further expansion, the focus
will then be on the support of automated driving and networked traffic
One of the main advantages of
C-ITS is that information on traffic disruptions can be exchanged in real time.
If a vehicle detects an impairment that is important for other road users, this
is immediately communicated to the other compatible vehicles via radio, and
those equipped with C-ITS can have these messages displayed directly in the
vehicle. C-ITS can also enable emergency vehicles to navigate through the city
more quickly and public transport more efficiently if, for example, traffic
lights are switched intelligently.
The products and technology being provided by
Siemens Mobility facilitate the secure and direct infrastructure-to-vehicle and
vehicle-to-infrastructure connection, which creates the necessary framework and
conditions for the installation of C-ITS. Specifically, the Siemens Mobility Cooperative Management System (CMS) and RSU work together to link vehicles with infrastructure and traffic
management centers through an ITS-G5 connection. A broadcast technology that
provides secure communication between vehicles and the road.
As vehicles report their current position, speed,
and direction of travel via their Onboard Unit
(OBU), the RSU collects this information and communicates it to the CMS.
As the controlling mechanism, the CMS links and monitors all RSUs and utilizes
the received information to manage traffic more efficiently and in real time. The
CMS can send messages to road users via RSUs to alert on hazards and provide
latest traffic information. The bidirectional information exchange between RSUs
and OBUs is protected by a C-ITS specific Public Key Infrastructure, which
ensures a high level of security and privacy related requirements.
The Siemens Mobility products and
technology do not discriminate against any vehicle type, and the weatherproof RSU
has been developed in line with the very high Siemens Mobility security
