The study authors highlight that neighborhoods with predominantly Black, Hispanic and Latinx residents would benefit the most -- potentially reducing disproportionate pollution and health burdens in historically marginalized areas.

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.

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.

Now, researchers have built the first open-source tool to let planners do just that. Researchers have built TILE2NET, an open-source tool that uses aerial imagery and image-recognition to create complete maps of sidewalks and crosswalks. The tool can help planners, policymakers, and urbanists who want to expand pedestrian infrastructure.

In contrast, the share of transit, non-motorized, and taxicab (including ride-hailing) trips has steadily increased.

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.

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.

The surprising result, based on new hyper-local vegetation maps, points to the underappreciated importance of urban greenery in the carbon cycle.

The increase appears to be driven by well-documented increases in crash-related deaths during large motorcycle rallies. Researchers say that the findings should serve as an alarm bell to rally organizers to increase safety measures, and that health care system should be prepared to handle heightened demand for trauma care as well as organ transplantation around motorcycle-rally days.

This is apparent from the comparison of two measurement campaigns carried out by the German research aircraft HALO in 2017 and 2020. A new study suggests that around 40 percent of the reduction can be attributed to a decrease in anthropogenic emissions. These findings reflect the major impact of human activity on air quality and the significance of soot as an important air pollutant and climate driver in the Anthropocene, researchers report. 妈,08年2022年8月16:22:06美国东部时间 //www.koonmotors.com/releases/2022/08/220808162206.htm //www.koonmotors.com/releases/2022/07/220719130225.htm Research suggests a trio of roadway treatments would enable people age 65 and older to travel on foot more safely.

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.
