We are developing and testing new (and old) approaches to collecting information about people and the goods, activities, transportation choices, and their social, environmental, and economic context. We embrace mix-method approaches (and theoretical perspectives) to understand the complexity of human interaction in the city.
Benchmarking Vehicle Miles Traveled – PI Clifton (Portland Bureau of Transportation, 2019-2020) – This project will develop a methodology to provide consistent measures of how Portland is progressing towards its climate and transportation performance goals.
NSF Sustainable Urban Systems “New Mobility, Cities and Data” Workshop Report – On July 15-16 2019, a diverse group of university researchers and community stakeholders from Columbus, Ohio and Portland, Oregon participated in a workshop to explore issues surrounding new mobility technologies, sustainable urban systems and data.
