Pushing clocks back Down Under does not increase road traffic accidents
As Australia moves to ST, losing an hour of light at the end of the day, a study suggests there is no evidence that the time change increases road accidents. This Sunday marks the end of -Daylight Saving Time- (DST) in eastern Australia as states revert to -Standard Time- (ST) losing one hour of light at the end of the day.

Vehicle exhaust filters do not remove ’ultrafine’ pollution - new study
Filters fitted to vehicle exhaust systems to remove particulate matter pollution have limited impact on ultrafine particles, new research shows. o 3 minute read Airborne particles from vehicle emissions are a major contributor to air pollution levels. Exhaust filters designed to mitigate this pollution have been a legal requirement in new cars since 2011, and in heavy duty vehicles since 2013.

Using Modeling to Limit Infectious Disease Transmission at Airports and Train Stations
In crowded places, such as airports and train stations, social distancing is difficult to maintain and the risk of infectious disease transmission is increased. In order to reduce this risk, it is essential that we improve our understanding of the dynamics of disease transmission within such places and the effective mitigation measures that can be implemented at low cost.

Minimizing electric vehicles’ impact on the grid
Careful planning of charging station placement could lessen or eliminate the need for new power plants, a new study shows. Close National and global plans to combat climate change include increasing the electrification of vehicles and the percentage of electricity generated from renewable sources. But some projections show that these trends might require costly new power plants to meet peak loads in the evening when cars are plugged in after the workday.

Cheap charcoal air filters offer improvements to in-vehicle air quality
A cheap charcoal air filter can reduce nitrogen dioxide (NO2) inside vehicles by as much as 90%, compared to levels outside the vehicle. Research presented in a report by WM Air, the West Midlands Air Quality Improvement Programme at the University of Birmingham, shows that charcoal filters, which costs around £10-£20, can effectively remove NO2 from the air within vehicle cabins.

Where do stolen bikes go?
An experiment in Amsterdam reveals how pilfered bicycles are put to use. Close Amsterdam is one of the most bike-friendly major cities in the world. That also means the city is a happy hunting ground for thieves, who steal tens of thousands of bikes per year - a substantial chunk of the estimated 850,000 or so that Amsterdam residents own.

Calculate collision risks: The standing bearing as a basis
Prof. Darius Burschka learned it from sailors Calculate impending collisions of flying drones or cars in traffic in advance and thus avoid them: That is the goal of Darius Burschka. To do this, the professor at the Technical University of Munich (TUM) tracks every point of an image taken by the cameras of a drone in the air or a vehicle on the road.

Traffic flow on A4 Leiden improved by driving advice
Faculty of Civil Engineering and Geosciences Building 23 Stevinweg 1 2628 CN Delft Room: 4. Will traffic flow improve when motorists are assisted in their choice of main or parallel lanes? The answer is yes. Rijkswaterstaat, TU Delft and Zuid-Holland Bereikbaar conducted a pilot project in collaboration with Flitsmeister in the past months.

Autonomous steering system keeps human drivers engaged
Researchers from EPFL and JTEKT Corporation have developed an automated driving system based on the concept of 'collaborative steering', which aims to increase transportation safety, efficiency, and comfort by encouraging active interaction between autonomous vehicles and their human drivers. Autonomous driving technologies have already been integrated into many mass-produced vehicles, providing human drivers with steering assistance in tasks like centering a vehicle in its lane.

Is it safe? Why some animals fear using wildlife crossings
UCLA-led research on deer and elk could point the way toward crossing structures that are more effective for all species UCLA-led research on deer and elk could point the way toward crossing structures that are more effective for all species In recent years, humans have built wildlife crossings in high-traffic areas to prevent road accidents and give animals access to expanded habitats for mating and resources.

World’s first net zero transatlantic flight to fly from London in 2023
Researchers will work with Virgin Atlantic to launch the world's first transatlantic flight powered solely by sustainable aviation fuel. The passenger flight from London to New York will be fuelled by 100 per cent sustainable aviation fuel (SAF), combined with carbon removal through biochar credits - a material that traps and stores carbon taken from the atmosphere - making the flight net zero.

Most nitrogen deposition from aviation comes from high altitude
Aircraft emit nitrogen oxides and other emissions during both the LTO-phase (taxiing, take-off and landing) and when flying at high altitudes. These emissions return to the ground, resulting in nitrogen deposited over land and water bodies. Using an atmospheric model, researchers at TU Delft have quantified - for the first time - that in 2019 aviation was responsible for just under 1.2% of total global nitrogen deposition from all sources (anthropogenic and natural).

A prototype system which warns of natural phenomena dangerous for aviation developed
The ALARM research team, a European scientific project coordinated by Universidad Carlos III de Madrid (UC3M), has developed a new prototype early warning system to monitor natural phenomena that threaten the safety and efficiency of aviation. This system, currently capable of predicting the dispersion of volcanic ash or the progress of certain thunderstorms, also identifies the areas where the passage of aircraft has the greatest impact on climate change.

New test facility: How cold can fuel for diesel engines get?
In extreme cold, fuels can no longer be used - but how do you measure the possible minimum temperature? A test facility has now been developed for this purpose at the Vienna University of Technology . When it gets too cold, the car won't start. Certain components of fuels can precipitate at low temperatures, the fuel becomes cloudy and can no longer be used.

Lake Geneva consumers surveyed as part of a study on climate change
Over 10,000 people in both the French and Swiss parts of the Lake Geneva region have been surveyed on their transportation habits, as the first element of a broader EPFL study on consumer lifestyles and behavior. The study is being spearheaded by EPFL's School of Architecture, Civil and Environmental Engineering (ENAC), working in association with the Canton of Vaud, the Canton of Geneva and Greater Geneva.

UT improves wind tunnel measurements for low noise aircraft design
Aircraft noise is an irritating source of ambient noise and a significant cause of stress for local residents and animals in the vicinity of airports. Reducing aircraft noise is a major social issue in the Netherlands, as evidenced by the discussions on the permitted number of flight movements at Schiphol.

Playing Nice: How Self-driving Cars and Human-driven Cars Could Share the Road
Akin to when Model Ts traveled alongside horses and buggies, autonomous vehicles (AVs) and human-driven vehicles (HVs) will someday share the road. How to best manage the rise of AVs is the topic of a new Carnegie Mellon University policy brief, " Mixed-Autonomy Era of Transportation: Resilience & Autonomous Fleet Management." Debate continues as to when AVs will dominate the streets, but one of the brief's authors, Carlee Joe-Wong , said, "Once AVs begin to deploy, there's probably not going to be any going back.
