An intelligent traffic system will be deployed on Austrian motorways
The digitization of roads and traffic management is an essential component of future mobility
Austrian public road operator Asfinag chose Siemens Mobility to provide technology for an intelligent traffic management system that facilitates the exchange of safety information between vehicles and the road.
The Cooperative Intelligent Transportation System (C-ITS) is a traffic management system that uses broadcast technology to analyze road conditions and broadcast information to motorists about traffic jams, accidents and lane closures.
Asfinag (German acronym for ‘motorway and highway finance joint-stock company’) claims to be the first infrastructure provider in Europe to install a network connecting vehicles and the road.
“The direct connection with our customers makes an important contribution to safe, efficient and sustainable mobility,” said Josef Fiala, CEO of Asfinag.
The process of installing the equipment along 2,200 km of highways and highways in Austria is underway. This includes the deployment of up to 525 Siemens mobility roadside units (RSUs), as well as the establishment of a control center. The first C-ITS services that will provide hazard warning services are expected to go live within the next 16 months. With further expansion, the focus will then be on supporting automated driving and network traffic management.
According to Siemens, one of the main advantages of C-ITS is that information about traffic disruptions can be exchanged in real time. If a vehicle detects a significant impairment for other road users, it is immediately communicated to other compatible vehicles by radio, and those equipped with C-ITS can have these messages displayed directly in the vehicle.
“We believe that smart communication and technologies that connect vehicles of all kinds to smart infrastructure help cities, or in this case road authorities, manage their mobility and improve their quality of life, by drastically reducing traffic congestion. , accidents and emissions”
C-ITS can also allow emergency vehicles to move faster around the city and public transport more efficiently if, for example, traffic lights are switched intelligently.
“Digitalization of road 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.

The products and technology provided by Siemens Mobility facilitate the direct and secure connection of the infrastructure to the vehicle and the vehicle to the infrastructure, which creates the framework and the conditions necessary for the installation of the C-ITS.
“The digitization of roads and traffic management is an essential component of future mobility”
Specifically, Siemens’ Cooperative Mobility Management System (CMS) and RSU work together to connect vehicles to infrastructure and traffic management centers via 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 on-board unit (OBU), the RSU collects this information and communicates it to the CMS. As a control mechanism, the CMS links and monitors all RSUs and uses the information received to manage traffic more efficiently and in real time. The CMS can send messages to road users via RSUs to alert of hazards and provide the latest traffic information.
Siemens Mobility said its products and technology do not discriminate against any type of vehicle and that the weatherproof RSU was developed in accordance with Siemens Mobility safety standards.
