Travel-time proxy only. No measured clinical outcomes or operational recommendation.
Same selected station pair and demand. Compare delivery strategies on equal footing.
Demand-weighted expected time to blood, including hospital fallback.
Illustrative inputs. Replace with agency and vendor estimates.
What is supplied, what is assumed, and what comes next.
Import a CSV with lat, lon, weight and optional id, name. Weight can represent aggregated incident count or an agreed severity score. Only de-identified geographic demand is needed.

Imported demand stays in this page's memory and clears on reload. The current candidate network is limited to Allegany County. Points outside the local region require review and may need additional stations.
Exact pair enumeration. Explicit assumptions. Reproducible scenario outputs.
Ground minutes = dispatch minutes + 60 × straight-line miles × road factor ÷ mph. Hospital minutes use the same travel estimate to UPMC Western Maryland + assumed scene/receiving delay. Each demand point uses the faster available pathway.
Demand is weighted by incident weight × (1 + remoteness priority × min(H / 30, 2)), where H is hospital time in minutes. The search minimizes this weighted expected time over every eligible station pair. Distance from the hospital alone does not earn a higher score.
Drone time includes launch/handoff and straight-line flight, with a one-way range limit. Unavailable flights fall back to hospital access; hybrid also retains ground delivery. Coverage applies the target separately to available and unavailable states.
Station assignments, speeds, road factors, operating availability, demand weights and all costs are scenario inputs. No road routing, elevation, concurrent calls, blood inventory, replenishment, traffic, staffing or survival model is included. The default hospital is UPMC Western Maryland; the other supplied trauma centers are reference data and are not interchangeable local blood access destinations.
Source records retained, including missing coordinates and co-located services.
