Shared e-scooters and similar new services are changing how people get around and are reshaping public transit. But who benefits, and who bears the costs?

What they work on

  1. Create a framework that scores the positive and negative effects of emerging systems such as shared e-scooters on different population groups with multi-level utility functions, combined by a social welfare function.
  2. Develop optimization models that preserve fairness under changing operations, solved with a customized Benders decomposition and a specialized procedure for generating and selecting strong Benders cuts.
  3. Estimate the price of fairness, the efficiency lost for a given fairness level, using a data-driven uncertainty set, and analyze tradeoffs in a shared micro-mobility case study with public data.

More about the research

Measuring fairness in these systems is hard because demand, vehicle locations and operations shift constantly, and different groups of people and stakeholders want conflicting things. This collaborative project develops ways to measure and preserve fairness in such emerging infrastructure, with attention to disadvantaged populations.

Why it matters

Cities and policymakers deciding how to regulate e-scooter and other micro-mobility services could use these fairness measures and tradeoff estimates to ensure services do not leave disadvantaged communities behind. They could also judge how much efficiency a fairer design would cost.

Known grants

From NIH and NSF research grants. Labs often have other funding we can't see.
