How drive times are measured
Every 2020 census block group (about 240,000 neighborhoods) starts from its population center and drives the OpenStreetMap road network to the nearest of the emergency rooms. Speeds come from posted limits where they are mapped and typical speeds by road type elsewhere, with a small delay at each intersection. They are free-flow times: no traffic. Ferries count at their scheduled duration.
Counties and tracts show the population-weighted median of their block groups, so half of residents are at or under the time shown. Searches stop at 3 hours. Puerto Rico and a few dozen roadless places in Alaska aren't covered.
