Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory are partnering with the City of Oak Ridge to develop UrbanSense, a comprehensive sensor network and real-time visualization platform that helps cities evaluate trends in urban activity.

The project, initiated by ORNL’s Urban Dynamics Institute, centers on addressing cities’ real-world challenges through applied urban science. Oak Ridge is the first city to test the new technology, which uses open-source, anonymous data from virtual and physical sensors.

“Preparing for urban growth and planning for future infrastructure development and resource demands are global problems, but cities need ways to be proactive on a local level,” said UDI Director Budhendra Bhaduri. “Our goal in bringing science to cities is to put the right tools and resources in the hands of city managers and urban planners so that they can assess local impacts and make strategic decisions to get the best return on future investments.”

UDI researchers Teja Kuruganti and Gautam Thakur from ORNL’s Computer Science and Engineering Division are collaborating with Oak Ridge Director of Administrative Services Bruce Applegate on the design and deployment of UrbanSense.

The prototype designed for Oak Ridge monitors population density, traffic flow, and environmental data including air and water quality, with a total of seven sensors to be installed in the city. “The longer they are in place and the more data they collect, the better the city’s sense of its trends will be,” Thakur said.

ORNL: High-resolution modeling assesses impact of cities on river ecosystems

A new study from Oak Ridge National Laboratory shows the far-reaching impacts of U.S. cities’ energy consumption on regional ecosystems. Urban areas cover only about 5 percent of the Southeast’s landscape, but cities’ water and energy infrastructures often extend well beyond urban areas as power plants (represented as black dots) are distributed throughout the entire region.

New mapping methods developed by researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory can help urban planners minimize the environmental impacts of cities’ water and energy demands on surrounding stream ecologies, a press release said.

In an analysis published in Proceedings of the National Academy of Sciences, an ORNL-led team used high-resolution geospatial modeling to quantify the effects of land, energy, and water infrastructures on the nation’s rivers and streams.

Using streamflow data from the U.S. Geological Survey, the researchers mapped changes to natural hydrology to assess how infrastructure development and competition over water resources affects the environment at a national scale. Their data-driven approach sheds light on the extent to which water resources and aquatic species are affected by urban infrastructures and could help cities curb their burden on regional ecosystems, the press release said.

The results indicate that urban land transformation and electricity production together affect 7 percent of U.S. streams, which influence habitats for more than 60 percent of all North American freshwater fish, mussel, and crayfish species, the release said. [Read more…]

Leading experts present challenges during ORAU annual meeting

Today’s scientists working with big data to identify the next breakthrough in medical care, environmental solutions, or other critical areas need to be skillful in data analytics but also adept at communications. That was one of the key insights attendees heard recently at ORAU’s 70th annual meeting of its Council of Sponsoring Institutions, titled “Big Data Analytics: Challenges and Opportunities.”

“For science to prosper, the science-society relationship must be positive and strong,” said keynote speaker Alan Leshner, chief executive officer emeritus for the American Association for the Advancement of Science, or AAAS. Leshner, who holds a doctorate in physiological psychology from Rutgers University, told the audience that many scientists are not prepared to talk about their work and its implications with the public.

Researchers at Oak Ridge National Laboratory have developed a population distribution model that provides unprecedented county-level predictions of where people will live in the United States in the coming decades.

Initially developed to assist in the siting of new energy infrastructure, the team’s model has a broad range of implications from urban planning to climate change adaptation. The study is published in the journal Proceedings of the National Academy of Sciences.

“We do a census every 10 years because those data help us do long-term socioeconomic planning,” said Budhendra Bhaduri, who leads ORNL’s Geographic Information Science and Technology group. “Population projection numbers are important, but many pressing societal needs also require an understanding of where people are going to be. This has always been a challenge; we’ve never had a good method to make future projections spatially explicit.” [Read more…]
