  • Taxiforall Incentivized Taxi Actuation System for Balanced Areawide Service
    Taxi-for-all: Incentivized Taxi Actuation System for Balanced Area-wide Service
    Joe-Wong, Carlee ;
    Noh, Haeyoung
    2021-07-01 | PDF
    This project develops a method to incentivize taxis to travel to different parts of a city so that they sense data or pick up passengers in under-served areas. Taxis' natural movement generally leads to them concentrating in busy locations with many potential passengers. By incentivizing taxis to move towards less busy locations, one can even out t ...
  • Applying Levelized Cost of Storage Methodology to UtilityScale SecondLife LithiumIon Battery Energy Storage Systems
    Applying Levelized Cost of Storage Methodology to Utility-Scale Second-Life Lithium-Ion Battery Energy Storage Systems
    Steckel, Tobiah ;
    Kendall, Alissa
    2021-07-01 | PDF
    The dramatic increase in electric vehicle (EV) sales has led to a rapid increase in deployed lithium-ion battery (LIB) capacity over the last decade. As EV batteries age and are retired from use in vehicles, they will require management. Second-life applications are often proposed as an environmentally and economically preferable management strateg ...

    2021-07-01 | PDF
    Very little research has been conducted on the second (and third, and thereafter) owners of new technologies. For light duty vehicles, the research has been focused on the first owners. In the case of plug-in electric vehicles (PEVs), understanding the secondary market is especially important for many reasons, including the vehicle market developme ...

    2021-07-01 | PDF
    The ability of persons and communities to reliably access transit is a pressing one that has not yet received significant attention in the literature on city planning, in public discourse, or in policy research. This scoping review focuses on factors that negatively impact a person or community’s ability to have reliable access to transit; we call ...

    This project examines commonalities and differences among disadvantaged neighborhoods in mobility and access to opportunities. Our approach is based on the concept of spatial-transportation mismatch (STM), which asserts that spatial distance and poor transportation are potential barriers to opportunities beyond one’s immediate location. The project ...
