AI Fleet Coordination Reveals Trip-Length and Spatial Inequity in Manhattan, Chicago, and San Francisco

ai-technology · 2026-07-29

A new study from arXiv (2607.24336) diagnoses delay inequity in autonomous vehicle fleet coordination. Using real road-network and taxi-demand data from Manhattan, Chicago, and San Francisco, researchers conducted a distributional audit revealing pervasive trip-length inequity that varies by city and coordinator. Spatial inequity intensifies with demand, especially when trips are grouped by origin. The paper proposes SPARE (Spatially Aware Rerouting), a budgeted online framework that assigns limited replanning capacity to delayed vehicles using observed waiting pressure. SPARE provides per-review decision guarantees and bounds online route updates. Experiments across all three datasets against six baselines demonstrate its effectiveness.

Key facts

  • Study uses real-city road-network and taxi-demand datasets from Manhattan, Chicago, and San Francisco.
  • Audit reveals pervasive trip-length inequity depending on city and coordinator.
  • Spatial inequity becomes more pronounced as demand grows.
  • Inequity is stronger when trips are grouped by origin rather than destination.
  • SPARE framework assigns limited replanning capacity to delayed vehicles.
  • SPARE uses recently observed waiting pressure for rerouting.
  • SPARE provides a per-review decision guarantee.
  • Experiments conducted against six baselines on all three datasets.
