About TransitShield

Superstorm Sandy put a price on the question TransitShield answers: when the climate turns, which parts of the subway fail first, and how many riders does that strand? Aging infrastructure, coastal flood risk, and ridership are spatially mismatched — the most exposed, least reliable stations are not always the ones with the most riders, and hardening budgets are finite.

TransitShield turns authoritative, keyless public data into a transparent, station-level climate-resilience risk score and a ranked, explainable list of the highest-risk stations — with every number traceable to its source and every limitation stated plainly.

Who it's for

Transit-agency capital planners prioritizing station hardening, resilience and emergency-management officers, climate-adaptation and infrastructure-finance analysts, and civic-technology and transportation-equity researchers.
