Facing a critical obstacle to better predictions of vehicle pollution, a research team from NAU turned to an untapped data source: Arizonans. And to encourage data collection, they\u2019re kickstarting a monthlong competition for middle and high school students throughout the state.<\/span>\u00a0<\/span><\/p>\n

Led by professor Kevin Gurney<\/strong>, members of the <\/span>Gurney Lab<\/span><\/a> in the School of Informatics, Computing, and Cyber Systems (SICCS) built the mobile app Hestia Traffic, which has both manual and AI-enabled versions. Anybody can use Hestia Traffic to collect crucial data about the size and distribution of vehicles on roads throughout Arizona.\u00a0<\/span>\u00a0<\/span><\/p>\n

\u201cExisting information about vehicles on roads was simply too coarse for the type of modeling we are doing,\u201d said Helen Rowe<\/strong>, an associate research professor in the School of Earth and Sustainability and lead scientist on the project. \u201cThe traffic app provides information at the scale of individual roadways, where people experience pollution and extreme heat.\u201d<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

After preliminary collection of data and beta testing, the team is now turning to K-12 students\u2014and creating a friendly competition\u2014to assist with data collection.<\/span>\u00a0<\/span><\/p>\n

\u201cWe\u2019ve created a new curriculum to inspire the next generation of community scientists,\u201d said Edgar Ochoa, a sixth-grade teacher at Ed & Verma Pastor Elementary School in Phoenix and the lead in propagating the competition to teachers across Arizona. \u201cThis curriculum will inspire the next generation to engage and participate in science, collecting data that improves our understanding of natural and built environments.\u201d<\/span>\u00a0<\/span><\/p>\n

Participation also gives students experience and skills with technical tools that will benefit them throughout their education and in Arizona\u2019s increasingly tech-focused workforce.<\/span>\u00a0<\/span><\/p>\n

\u201cThe project allows students to learn by hands-on interaction with the world around them while still using the technology that has become such an integral part of their lives,\u201d said Anna Kato<\/strong>, a research scientist in SICCS who helped design the app.<\/span>\u00a0<\/span><\/p>\n

The statewide competition will recognize the individual student and school that can earn the most \u201cpoints\u201d through the app. The competition runs from Oct. 20 to Nov. 21, and all students from 6<\/span>th<\/span> to 12<\/span>th<\/span> grade are eligible to compete for the individual award. To further engage the entire school community, teachers, other school staff and parents can earn points that will go toward each school\u2019s total. The goal is to encourage as many people as possible to gather data for their community.<\/span>\u00a0<\/span><\/p>\n

The project is part of a larger U.S. Department of Energy-funded initiative across Arizona called the Southwest Urban Integrated Field Laboratory (SW-IFL), which addresses extreme heat, air pollution and climate change in Arizona cities through research led by the three public universities in Arizona, two national laboratories and various industry partners.<\/span>\u00a0<\/span><\/p>\n

Gurney<\/span><\/a>, a co-lead of the SW-IFL project, has authored more than 175 scientific publications, including a recent U.S. National Academy Report, \u201cGreenhouse Gas Emissions for Decisionmaking.\u201d He has been involved with the United Nations Climate Change Framework Convention and the Kyoto Protocol for more than 25 years and is a lead author for the Intergovernmental Panel on Climate Change.<\/span>\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
