Abstract:
Transportation is the single largest source of carbon emissions in the US. Decarbonizing it is challenging because it depends on individual behaviors, which in turn, depend on local land use planning. The interdisciplinary field of Computational Mobility (CM), which focuses on collecting, analysing and influencing human travel behavior, can frame solutions to this challenge. Most prior Human Mobility Systems (HMSes) have been purely applied, lacking bidirectional flow between the two disciplines, and focused on study results instead of system design.

In this talk, I introduce the idea of Computational Mobility and link it to e-mission, an extensible platform whose modular architecture, use of virtual sensors, and reproducib
le pipeline form a robust foundation for CM. I present the first empirical evaluation of HMSes that focuses on system design. The architectural evaluation is based on three archetypal real-world deployments, and the power/accuracy/analysis tradeoffs are based on a novel procedure that uses artificial trips and multiple parallel phones to mitigate concerns over privacy, context sensitive power consumption and inherent sensing error. I end by outlining future innovations in both computation and mobility enabled by the platform.
