Satellite data and digital maps are to protect against wrong-way drivers

23.10.2015

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.


Wrong-way drivers at motorway junctions

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.

Im Focus: New measurement exacerbates old problem

Two prominent X-ray emission lines of highly charged iron have puzzled astrophysicists for decades: their measured and calculated brightness ratios always disagree. This hinders good determinations of plasma temperatures and densities. New, careful high-precision measurements, together with top-level calculations now exclude all hitherto proposed explanations for this discrepancy, and thus deepen the problem.

Hot astrophysical plasmas fill the intergalactic space, and brightly shine in stellar coronae, active galactic nuclei, and supernova remnants. They contain...

Im Focus: Biotechnology: Triggered by light, a novel way to switch on an enzyme

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".
