The Socially Aware Mobility project takes a collaborative and dynamic approach to the research process. Along with a multidisciplinary research team, an advisory board comprised of strategic local partners provides feedback and guides the research process. The project works in coordination with the Smart Cities and Inclusive Innovation initiative at Georgia Tech.



A multidisciplinary approach

The Socially Aware Mobility project includes collaborations with faculty from the H. Milton Stewart School of Industrial and Systems Engineering (ISyE), the School of Civil and Environmental Engineering, and the School of City and Regional Planning at Georgia Tech. The project is led by Pascal Van Hentenryck, A. Russell Chandler III Chair and professor at ISyE. He manages a team of post-doctorate and graduate students conducting the primary research for the project. Alongside this team, Van Hentenryck also runs a Vertically Integrated Partnership, “Reinventing Mobility in Atlanta” project, which incorporates undergraduate and senior design students into the research.
