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.

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...
Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.
Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...
The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
