Priority Truck Stops

Where intervention is most urgent, ranked by AM-baseline deficit — not synced to the live scenario controls.

Fleet size is set in below.

Equity-weighted ranking

Stations near NYCHA or a school, or beyond the subway gap, rank higher and may displace others in this list.

Scenario Planner Adjust weather or equity thresholds — the map updates live. Weather projections carry a PROJECTED tag. No effect in Live Docks mode.

Equity Gap

Compares stations currently reporting 0 bikes or 0 docks (live GBFS), grouped by whether they're within your current NYCHA, school, and subway-gap thresholds — a snapshot, not a historical frequency.

Fleet & Routing

Fleet sizing is the operator's decision — included here for completeness.

Fleet size: 1 truck(s)

Stations cleared per truck added

Checked against real data, not assumed: added trucks do not show smoothly diminishing returns at this scale. Every truck hits its own 45-stop shift cap before ever running out of flagged stations, so the binding constraint here is each truck's per-shift stop budget, not overall demand.

Glossary

Double-outage: A station with 0 bikes or 0 docks that also has another empty/full station within 500 m — a compounding failure, not just one broken station.
Net Daily Flow: A station's average net arrivals minus departures at a given hour, in bikes/day — averaged across the days observed, not a 24-hour total.
Elasticity: How much a station's bike flow shifts with temperature and precipitation, fit from a real regression against a full year of historical weather and ridership.
Equity Gap: How much worse live service is at stations near NYCHA housing, schools, or far from a subway, compared with other stations right now.
Typology: A station's behavioral archetype — e.g. “Commuter core” or “Residential feeder” — from clustering real hourly flow patterns, not from neighborhood or borough.
Service Availability (Now): The share of stations not currently in double-outage — an instant reading, not the 60-minute measurement the underlying contract actually defines.
