Telematics solution to increase traffic safety
Wrong-way drivers driving against the permitted direction of traffic cause almost 2,000 traffic accidents with approximately 20 fatalities on German motorways every year. Attempts to get to grips with the problem through improved signposting or technical measures have not shown the desired effect or rather have failed due to the costs.
The Institutes for Engineering Geodesy from the University of Stuttgart (IIGS) and for Space Technology and Space Exploitation (ISTA) from the Bundeswehr University Munich as well as the company NavCert are now researching a wrong-way driver alert system in the framework of the project “Ghost Hunter“, that is based on a global navigation satellite system (GNSS).
The main causes for wrong-way driving are, among others, consciously turning round on the motorway as well as driving under the influence of alcohol. Added to this is accidental one-way driving whereby the driver simply loses his or her bearings. Wrong-way driving often begins at motorway junctions or in the area of accesses and exits.
Various measures have already been put in place at these neuralgic points in Germany and also in some other countries to prevent wrong-way driving, for instance stop signs, more easily recognisable signposting, road driving claws, induction loops or wireless sensors.
The comprehensive introduction of these safety measures, however, has failed up to now due to the considerable work and cost expenditure. In order to reduce these costs, technical solutions to the wrong-way driving problem have primarily been researched in recent years.
Yet how is it possible to detect wrong-way driving at an early stage and reliably, make wrong-way drivers efficiently aware of what they are doing and warn endangered road users in the surrounding area? In the project “Ghost Hunter“, that is supported by the German Aerospace Centre resp. the Federal Ministry for the Economy and Energy with funds amounting to around 670,000 Euros, scientists are resorting to a selected research method to solve this problem.
This brings the research fields GNSS (including vehicle navigation and sensor fusion) as well as geo-informatics (incl. digital map systems and map-matching technologies) together in order to develop a wrong-way-driver early detection system. The system to be developed is to determine the position of a vehicle with the help of GNSS and other sensors and compare them with a digital map so that the decision can be made as to whether a wrong-way driver is on the road or not.
For this purpose the ISTA will develop a robust (D)GNSS-based algorithm to record exact vehicle trajectories (movement paths) and a wrong-way-driver detection algorithm. The IIGS will investigate data qualities of digital road maps of various map providers and develop a map-matching tool and integrate it in the wrong-way-driver alert system.
Ultimately the new automatic alert system is to be implemented in the European emergency system eCall that will by law have to be installed from 2018 in all new models of cars and light commercial vehicles. By using these modern scientific technical methods the wrong-way-driver alert system is to be enabled in future to protect against wrong-way drivers on motorways and consequently lead to more road safety and fewer accidents.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
