Green Light for Vehicle-to-Infrastructure Communications

24.09.2015

In the context of an EU project that began in 2013 and will end in 2015, Siemens and its partners are testing ways in which the exchange of information between drivers and traffic lights can make traffic safer and more efficient.

A number of vehicles and traffic lights along two main traffic arteries in Newcastle, U.K, were recently equipped with communication units. Drivers receive information on the duration of the current light phase and an indication of the speed at which they are most likely to reach the green phases or whether they should turn off their engines at a red light.


The Communicating Cars initiative demonstrates the practical benefits of intelligent transport systems (ITS) and their suitability for everyday use on the roads of Europe.

Whenever possible, the test vehicles also receive a green signal from the control center. Data on the flow of traffic and exhaust emissions will be collected until the end of this year. This information is expected to show that the technology can make traffic at intersections safer, more fluid, and more energy-efficient while lowering emissions. Newcastle University is heading the project, with Siemens and the city government as part of the team.

Experts believe that networking cars with each other and with traffic control centers is an important way to avoid congestion and accidents in urban traffic. The real-time exchange of warnings and information on traffic flow allows drivers to prepare for potentially challenging conditions.

Control centers can use the resulting data to fine-tune the switching patterns of their signaling systems. They can also grant priority to certain vehicles, such as emergency teams. Networked communication among cars and infrastructure is generally creating the conditions necessary for the future automation of urban traffic.

Real-Time Networking

The Newcastle tests are part of the EU’s Compass4D project. The project has been evaluating different applications of cooperative, intelligent traffic systems in seven cities. Siemens, one of the Compas4D partners, has long developed hardware and software solutions for cooperative traffic systems with Corporate Technology, its corporate research department, as well as the Mobility Division. Siemens is also involved in a number of European test fields.

In Newcastle, twelve vehicles belonging to an ambulance service, two electric cars provided by the university and 20 signaling systems were equipped with communication units. Ten times per second, on-board units in the vehicles transmit status messages to so-called roadside units, which are integrated into the traffic lights. The roadside units forward the information to the traffic control center. Communication takes place using a WLAN standard that was specially developed for intelligent traffic systems. Drivers can use an app to display the information from the control center on a tablet. They can check the countdown to the next light change and receive tips on the best route to take under current driving conditions. When a test vehicle reaches a point 200 meters from a traffic light, the light turns green whenever possible.

From Industrial Environments to Traffic Light Management

In the Newcastle project, Siemens is primarily responsible for the roadside units and the exchange of data between cars and the traffic control center. This includes integrating the roadside units with the app, the on-board unit and the traffic control software. The roadside units are based on Scalance systems, which were originally used for communications in industrial plants. In recent years, researchers with Corporate Technology have adapted these units for intelligent traffic systems and developed entirely new software for them. The Scalance systems have since been deployed in a number of test fields.

Im Focus: New Pitt research finds carbon nanotubes show a love/hate relationship with water

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.

New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...

Im Focus: Magnets for the second dimension

If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it. What happens is that the magnets always arrange themselves in a column sticking out vertically from the magnetic board. Moreover, it's almost impossible to join several rows of these magnets together to form a flat surface. That's because magnets are dipolar. Equal poles repel each other, with the north pole of one magnet always attaching itself to the south pole of another and vice versa. This explains why they form a column with all the magnets aligned the same way.

Now, scientists at ETH Zurich have managed to create magnetic building blocks in the shape of cubes that - for the first time ever - can be joined together to...

Im Focus: Distorted Atoms

In two experiments performed at the free-electron laser FLASH in Hamburg a cooperation led by physicists from the Heidelberg Max Planck Institute for Nuclear physics (MPIK) demonstrated strongly-driven nonlinear interaction of ultrashort extreme-ultraviolet (XUV) laser pulses with atoms and ions. The powerful excitation of an electron pair in helium was found to compete with the ultrafast decay, which temporarily may even lead to population inversion. Resonant transitions in doubly charged neon ions were shifted in energy, and observed by XUV-XUV pump-probe transient absorption spectroscopy.

An international team led by physicists from the MPIK reports on new results for efficient two-electron excitations in helium driven by strong and ultrashort...

Im Focus: A Memory Effect at Single-Atom Level

An international research group has observed new quantum properties on an artificial giant atom and has now published its results in the high-ranking journal Nature Physics. The quantum system under investigation apparently has a memory - a new finding that could be used to build a quantum computer.

The research group, consisting of German, Swedish and Indian scientists, has investigated an artificial quantum system and found new properties.
