P2P traffic control

Wireless technology could reduce congestion, accidents

Could a concept from information technology familiar to online file sharers be exploited to reduce road congestion and even traffic accidents? That is the question answered in the affirmative by researchers in California, writing in the International Journal of Vehicle Information and Communication Systems.

Trevor Harmon, James Marca, Pete Martini, and Raymond Klefstad of the University of California, Irvine, explain that one of the key failings of modern transport systems is the inept collection and distribution of usable traffic information. According to one US survey, they point out that less than a third of signaled intersections on arterial roads had any form of electronic surveillance. In other words, around 70% of all traffic lights have no electronic monitoring and this does not take into account the regions between traffic signals.

"The unfortunate consequence is," they say, "that, even if every highway were fully and accurately monitored, drivers attempting to plot an alternative route around an incident would have virtually no information about conditions on the arterial street network."

They explain that there is research currently underway to address this issue using local-area wireless technology. This technology will allow vehicles to form an ad hoc network that can exchange timely information about traffic conditions, incidents, and accidents. The research team has a vision for such a traveler-centric, zero-infrastructure system they have named Autonet. This network would share information through a peer-to-peer (P2P) system akin to those used by file sharers on the internet but exchanging useful traffic information rather than music and video files.

The team has already carried out a validation of the Autonet system. In the prototype based on readily available 802.11b wireless technology, they explain, an in-vehicle computer "client" with an informative graphical user interface (GUI) continuously monitors other nearby clients on the wireless network, exchanging knowledge about local road conditions.

The system can handle measurements for approximately 3,500 traffic incidents for two vehicles passing each other at highway speeds, the team asserts. They point out that not all the wireless clients in the network need be vehicles, roadside monitoring posts could be embedded in the network too.

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

Im Focus: The first precise measurement of a single molecule's effective charge

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
