Bois de la Cambre in Brussels: park or thoroughfare?
VUB and ULB research into traffic preferences shows divide between respondents in centre and periphery Sunday, May 30, 2021 — Traffic in the Bois de la Cambre in Brussels has been the subject of intense debate for some time. Should it be open or closed to traffic? Researchers from VUB and ULB, with the Brussels Studies Institute (BSI), conducted a survey on people's wishes for the park.

New early warning system for self-driving cars
New early warning system for self-driving cars
AI recognizes potentially critical traffic situations seven seconds in advance A team of researchers at the Technical University of Munich (TUM) has developed a new early warning system for vehicles that uses artificial intelligence to learn from thousands of real traffic situations. A study of the system was carried out in cooperation with the BMW Group.

How do you know where volcanic ash will end up?
How do you know where volcanic ash will end up?
A team from the University of Geneva studied the ash from volcanic eruptions and discovered two effects of ash sedimentation that will improve our ability to predict the danger posed by volcanic ash clouds. When the Eyjafjallajökull volcano in Iceland erupted in April 2010, air traffic was interrupted for six days and then disrupted until May.

Rotor head full fairing makes the RACER fly faster
Rotor head full fairing makes the RACER fly faster
Aerodynamic shape optimization for helicopter rotor heads Helicopters are to become faster, greener and quieter. An international team led by Airbus Helicopters (AH) is working on the technology to achieve these goals with the RACER demonstrator. Scientists from the Technical University of Munich (TUM) have designed an aerodynamically shape-optimized rotor head full fairing for the innovative RACER rotorcraft.

A memory without a brain
A memory without a brain
How a single cell slime mold makes smart decisions without a central nervous system Having a memory of past events enables us to take smarter decisions about the future. Researchers at the Max-Planck Institute for Dynamics and Self-Organization (MPI-DS) and the Technical University of Munich (TUM) have now identified how the slime mold Physarum polycephalum saves memories - although it has no nervous system.

Cucumber with twin
Cucumber with twin
Vegetables and fruits often have a long way to go on the supermarket shelf. How can quality be intelligently maintained on long journeys and possible spoilage prevented? In cooperation with Coop, Empa experts are developing a system that keeps an eye on freshness during transport - and at the same time allows optimization.

Getting to Net Zero - and Even Net Negative - is Surprisingly Feasible, and Affordable
Getting to Net Zero - and Even Net Negative - is Surprisingly Feasible, and Affordable
Reaching zero net emissions of carbon dioxide from energy and industry by 2050 can be accomplished by rebuilding U.S. energy infrastructure to run primarily on renewable energy, at a net cost of about $1 per person per day, according to new research published by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), the University of San Francisco (USF), and the consulting firm Evolved Energy Research.

Digital twin for autonomous driving
Digital twin for autonomous driving
Autonomous driving will come about. But how do you make it safe for each traffic situation, what transportation infrastructure will be required, and what will be the impact of future traffic models? Under the leadership of Audi AG, the SAVeNoW consortium is running a simulation on these questions using a digital twin of the urban traffic of Ingolstadt as an example.

ARAS test aircraft successfully completes maiden flight
ARAS test aircraft successfully completes maiden flight
Students of Aerospace Engineering at the University of Stuttgart have developed and built the unmanned testing platform Aircraft for Research and Applied Science (ARAS). In the process, they designed the components for it to be able to withstand high loads. After the mechanical and electronic integration was finished, the "UAStudents Gruppe" (a compound made up of Unmanned Aerial System, another word for drone, and students) carried out extensive ground testing before the aircraft successfully took off for the first time in October.

Nighttime aircraft noise can be fatal
Nighttime aircraft noise can be fatal
Short-term disturbances caused by aircraft noise at night can lead to cardiovascular death within hours. This is shown in analyses by a team of researchers from the Swiss Tropical and Public Health Institute and Empa. The researchers used a dataset covering the years 2000 to 2015 to investigate how mortality rates in the Zurich airport area are related to acute nighttime aircraft noise exposure; they recently published their findings in the European Heart Journal.

Military flights biggest cause of noise pollution on Olympic Peninsula
Military flights biggest cause of noise pollution on Olympic Peninsula
An area in the Olympic Peninsula's Hoh Rain Forest in Washington state for years held the distinction as one of the quietest places in the world. Deep within the diverse, lush, rainy landscape the sounds of human disturbance were noticeably absent.

On the way to optimised approach procedures
On the way to optimised approach procedures
Aircraft also make noise on approach, which is often underestimated. A research project involving Empa has shown that it is quite possible to reduce noise during approach, to avoid particularly loud approaches and at the same time to reduce fuel consumption. In the future, pilots shall receive software assistance to help them better manage the complex relationships between air traffic control, flight mechanics and environmental impact.

Airplane noise at night can trigger cardiovascular death
For the first time, a study demonstrated that loud night-time noise from airplanes can trigger a cardiovascular death within two hours. Researchers from the University of Basel, the Swiss Tropical and Public Health Institute (Swiss TPH) and partners compared mortality data with acute night-time noise exposure around Zurich airport between 2000 and 2015.

Noise and light pollution alter bird reproduction
Noise and light pollution alter bird reproduction
Looking for a bird's'eye view of human impact? A new study provides the most comprehensive picture yet of how human-caused noise and light pollution affect birds in North America, including how these factors may interact with or mask the impacts of climate change. Recent troubling findings suggest that North American bird populations have declined sharply in the last few decades.

Analysis: staying coronavirus safe on trains, planes and automobiles
Many of us rely on public transport to get to work, school, and to meet friends and family. But in the time of Covid-19, Dr Lena Ciric (UCL Civil, Environmental & Geomatic Engineering) asks: is it safe to use these vehicles and is there a difference between them? Transport has contributed to the spread of coronavirus - locally, regionally and internationally.

Volatile for heavy trucks
In future, commercial vehicles will not only have to emit less CO2 but also meet stricter exhaust emission limits. Many experts expect that this could herald the end for fossil diesel. One possible alternative is dimethyl ether: The highly volatile substance burns very cleanly and can be produced from renewable energy.

New Perception Metric Balances Reaction Time, Accuracy
Both elements are critical for applications such as self-driving cars Researchers at Carnegie Mellon University have developed a new metric for evaluating how well self-driving cars respond to changing road conditions and traffic, making it possible for the first time to compare perception systems for both accuracy and reaction time.

The accident preventers
Security software for autonomous vehicles Before autonomous vehicles participate in road traffic, they must demonstrate conclusively that they do not pose a danger to others. New software developed at the Technical University of Munich (TUM) prevents accidents by predicting different variants of a traffic situation every millisecond.

Routing apps can deliver real-time insights into traffic emissions
Routing apps such as Google Maps or Nokia's Here platform could offer a cost-effective way of calculating emission hotspots in real time, say researchers at the University of Birmingham. These apps routinely capture detailed information as motorists use the GPS technology to plan and navigate routes.
