Swift or safe? That may be the question drivers with navigation systems ask themselves in future.
A new study by researchers at the University of Toronto Intelligent Transportation Systems (ITS) Centre and Testbed suggests in-car systems, designed to guide drivers around traffic jams and accidents quickly, could actually cause a temporary surge in the risk of accidents. "Discovering that traveller information systems may be good for travel time but not for overall safety was shocking because they are generally supposed to provide benefits," says Professor Baher Abdulhai, the director of the ITS Centre and Testbed in the Department of Civil Engineering.
Using computer simulations of route guidance systems, Abdulhai’s team found accident risks peaked immediately after drivers were informed of traffic congestion and changed their routes. "There was an increased level of activity as people ’bailed out’ to bypass congestion," says Abdulhai - for example, as drivers left a jammed freeway for city streets and encountered accident-prone intersections. However, because drivers reach their destination sooner, the accompanying drop in accident risk eventually counterbalances the earlier surge.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
