This system prevents reckless drivers overtaking when it is not safe and can also aid cautious drivers in overtaking slower vehicles. This is the proposition of researcher ir. Geertje Hegeman, who will receive her PhD on this subject from TU Delft on Thursday 28 February.
Each year in the Netherlands at least 25 deaths are caused by overtaking manoeuvres that go wrong. In many other countries, the statistics are much higher. Researcher Geertje Hegeman has designed a warning system (the overtaking assistant) which displays a green light when it is safe to overtake another vehicle. If it is not safe, a red light is displayed. She has tested this in a driving simulator on a two-lane road. Her conclusion is that the overtaking assistant increases the driver’s sense of ease and can have a positive effect on safety and efficiency.Men and women
One interesting aspect of the study conducted by Hegeman in the driving simulator is the differences in behaviour between men and women. Of the participating 12 men and 12 women, the women overtook more when driving using the assistant, while men in fact overtook less. This reduced the differences in driving behaviour between men and women. Furthermore, when using the assistant, men were less inclined to swerve to one side (they often do this to see whether there is any oncoming traffic), which is also beneficial to traffic safety.Inter-vehicle communication
In addition to GPS, inter-vehicle communication between all vehicles is in Hegeman’s view needed in order to give correct overtaking advice. This is already the subject of a great deal of study (e.g. with a view to anti-collision systems), but according to Hegeman it could be another ten years before the first overtaking assistants are commercially available.

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.
The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....
Researchers at Chalmers University of Technology, Sweden, have discovered a completely new way of capturing, amplifying and linking light to matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery, which was recently published in Nature Nanotechnology, opens up new possibilities in the world of nanophotonics.
Photonics is concerned with various means of using light. Fibre-optic communication is an example of photonics, as is the technology behind photodetectors and...
Fraunhofer IZM is joining the EUROPRACTICE IC Service platform. Together, the partners are making fan-out wafer level packaging (FOWLP) for electronic devices available and affordable even in small batches – and thus of interest to research institutes, universities, and SMEs. Costs can be significantly reduced by up to ten customers implementing individual fan-out wafer level packaging for their ICs or other components on a multi-project wafer. The target group includes any organization that does not produce in large quantities, but requires prototypes.
Research always means trying things out and daring to do new things. Research institutes, universities, and SMEs do not produce in large batches, but rather...
