The Cooperative Intelligent Transport System is a traffic management system that uses broadcast technology to analyse conditions for exchange of information between vehicles and the road.
Austrian public roads operator Asfinag has selected Siemens Mobility to provide the technology for an intelligent traffic management system that facilitates the exchange of safety information between vehicles and the road.
The Cooperative Intelligent Transport System (C-ITS) is a traffic management system that uses broadcast technology to analyse roadway conditions and disseminates information to motorists relating to traffic jams, accidents, and lane closures.
Asfinag (German acronym for “autobahn and highway financing stock corporation”) claims it is first infrastructure provider in Europe to install a network connecting vehicles and the road.
“The direct connection with our customers provides an important contribution to safe, efficient and sustainable mobility,” said Josef Fiala, managing director of Asfinag.
The process to install the equipment along 2,200km of highway and expressway in Austria is underway. This includes deploying up to 525 Siemens mobility road-side units (RSU), as well as establishing a control centre. 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 supporting automated driving and networked traffic management.
According to Siemens, 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.
“We believe Intelligent communication and technologies that connect vehicles of all kinds with smart infrastructure helps cities, or in this case highway authorities, manage their mobility and improve quality of life, by significantly reducing congestion, accidents and emissions”
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 digitalisation of roadway and traffic management is an essential component of future mobility and we are delighted to partner with Asfinag on this groundbreaking project,” said Markus Schlitt, CEO of Siemens Mobility Intelligent Traffic Systems.
“We believe intelligent communication and technologies that connect vehicles of all kinds with smart infrastructure helps cities, or in this case highway authorities, manage their mobility and improve quality of life, by significantly reducing congestion, accidents and emissions.”
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 centres through an ITS-G5 connection. The latter is 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 utilises 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.
Siemens Mobility said its products and technology do not discriminate against any vehicle type, and the weatherproof RSU has been developed in line with Siemens Mobility security standards.
