Thanks to the smart system, 75 traffic lights are connected in Vienna, which communicate with car drivers and cyclists via a mobile application, and provide better traffic flow on the 17-kilometer section. It is only a part of a large project of digitalization of traffic in the Austrian metropolis.

Reducing emissions from traffic is a key factor in the fight against climate change. In order to achieve its climate goals, the City of Vienna is investing in expanding its public transport network, offering car, bicycle or electric scooter sharing, and encouraging the switch to electric vehicles.

Smart and networked traffic systems increase road safety and contribute to climate protection. That is why the capital of Austria in cooperation with the company Kapsch TrafficCom, is implementing a pilot project that will, among other things, drastically reduce CO2 emissions thanks to better traffic flow.

The project reduces stress and emissions in urban traffic

In the testing phase, 75 traffic lights were connected on a section whose total length is 17 kilometers, and includes several Viennese, very busy streets. Traffic lights transmit information to users of the mobile application Vienna green wave (Green wave Vienna app) about the duration of the green light and the speed at which it is necessary to drive the “green wave” before the red light on the traffic light turns on. This allows car drivers and cyclists to adjust their speed in real time, while adhering to the limits. The app also shows the duration of the red light which allows the driver to react faster when starting the vehicle. This allows app users to participate in city traffic with less stress and greater fuel savings. Already at this stage of the project, CO2 emissions are expected to be reduced by 15 percent.

In order to avoid traffic jams, the next step should be the flexible operation of smart traffic lights that better regulate traffic and adapt to the actual amount of vehicles passing through the intersection, which should be implemented in the same area by mid-2023.

If the project proves successful, the digitalized traffic management system should be equipped with about 600 traffic lights on Vienna’s main roads in the next few years.
