But importantly, the new study also shows that wind farm noise isn't more disruptive to sleep than road traffic, which was a little more disruptive at the loudest audio level but not at more common levels. Sleep researchers have studied the impact of exposure to wind farm noise during sleep in three new scientific publications to better understand its impact.

Microchips inside the markers transmit information to passing cars about the road shape to help autonomous driving features function even when vehicle cameras or remote laser sensing, called LiDAR, are unreliable because of fog, snow, glare or other obstructions.

To understand additional impacts of this transition, researchers conducted life-cycle comparisons of battery-powered electric vehicle fleets to a gas-powered one, using real-world rideshare data. They found up to a 45% reduction in greenhouse gas emissions from full electrification; however, traffic problems and air pollution could increase.

Researchers report that alcohols in windshield washer fluid account for a larger fraction of real-world vehicle emissions than previous estimates have suggested. Notably, the levels of these non-fuel-derived gases will likely remain unchanged, even as more drivers transition from gas-powered to electric vehicles.

The model can estimate how landing volumes will influence those in consecutive hours -- a critical ability given airport capacity constraints and external events that cause landing delays. Altogether, the model demonstrates that statistical analyses of hourly plane landing volumes can yield valuable insights into airport operations.

The model uses a modified form of percolation theory, and the investigators considered the existing road network and population distribution in Shanghai. They generated trips between various population centers, assigning those trips to roads that provided the shortest travel distance, and discovered that a massive cascading failure of the urban transportation system occurred in a sudden and discontinuous fashion. Tue, 21 Mar 2023 11:26:56 EDT //www.koonmotors.com/releases/2023/03/230321112656.htm //www.koonmotors.com/releases/2023/03/230316140919.htm An increasing number of U.S. interstates are set to try out an invention that could save millions of taxpayer dollars and significantly reduce traffic delays. The invention, a sensor that allows concrete to 'talk,' decreases construction time and how often concrete pavement needs repairs while also improving the road’s sustainability and cutting its carbon footprint. Embedded directly into a concrete pour, the sensor sends engineers more precise and consistent data about the concrete’s strength and need for repair than is possible with currently used tools and methods.

To do so, a researcher used data from a main car-sharing company in Italy as a proxy for overall city traffic. Understanding how different urban zones interact can help avoid traffic jams, for example, and enable targeted responses of policy makers -- such as local expansion of public transportation.

Digital markers refer to variables generated from data captured through recording devices in the real-world setting. These data could be processed to measure driving behavior, performance and tempo-spatial pattern in exceptional detail. 星期四,2023年2月23日13:28:45 EST //www.koonmotors.com/releases/2023/02/230223132845.htm //www.koonmotors.com/releases/2023/02/230205081301.htm Researchers have developed autonomous driving software which distributes risk on the street in a fair manner. The algorithm contained in the software is considered to be the first to incorporate the 20 ethics recommendations of the EU Commission expert group, thus making significantly more differentiated decisions than previous algorithms. Operation of automated vehicles is to be made significantly safer by assessing the varying degrees of risk to pedestrians and motorists.

As our vehicles become more advanced and even autonomous, the ways of detecting and avoiding these collisions must evolve too. Current systems are often complicated, resource-intensive or work poorly in the dark. But now, researchers have designed a simple, power-saving collision detector inspired by the way insects avoid bumping into one another.

The automated system could reduce the time, costs and labor needed to find and repair air leaks, and it could lower the locomotive industry's overall fuel consumption and exhaust emissions.

Participants played out scenarios in virtual reality (VR) and had to decide whether to cross a road in front of a moving vehicle or not. When that vehicle was fitted with robotic eyes, which either looked at the pedestrian (registering their presence) or away (not registering them), the participants were able to make safer or more efficient choices.

To that end, researchers have developed a technique that allows autonomous vehicle software to make the relevant calculations more quickly -- improving both traffic and safety in simulated autonomous vehicle systems.

The artificial intelligence can safely avoid collisions, predict the intent of other aircraft, track aircraft and coordinate with their actions, and communicate over the radio with pilots and air traffic controllers. The researchers aim to develop the AI so the behaviors of their system will be indistinguishable from those of a human pilot.

Researchers have studied how publicly available mobility options in the Karlsruhe region in the future can optimally fulfill the citizens' needs. The result: Widespread availability of pooling and sharing services and improved public transportation will profit both -- and reduce car traffic.

Although the main financial and technological obstacles have been removed, their market share still needs to increase. In a recent study, a team investigated the cognitive factors that still dissuade many people from switching to electric cars. They found that car owners systematically underestimate the capacity of electric driving ranges to meet their daily needs.

This new study evaluated the effect of displaying crash death totals on highway message boards (e.g., '1669 deaths this year on Texas roads'). Versions of highway fatality messages have been displayed in at least 27 US states.

However, rebalancing the number of bikes at each port as time passes is essential, and finding the optimal routing paths for the vehicles in charge of rebalancing constitutes a combinatorial optimization problem. Now, scientists propose an innovative algorithm that can find near-optimal solutions more quickly even for a large number of ports, paving the way for more efficient bicycle sharing systems.

That's why sustainability experts propose a new way to analyze traffic congestion. Using more precise measures to describe the shape of cities and considering other socioeconomic factors, the model, which was applied to nearly 100 American cities, could lead to a better understanding of the link between congestion and land use.

The ability to predict exactly what those impacts will be, and plan for them, would be a major help to both transportation agencies and road users.

Future applications of these effects could include aiding autonomous vehicles in recognizing traffic signs, researchers say. Multiple images, including of a sign created using the material, are available.

These 10-day campaigns have been held twice yearly since 1952. The researchers acquired monthly road death data for 1949--2019 and modeled these 71 years of numbers. They found a 2.5% reduction in daily road deaths in 1952--2019 in the campaign months.
