Primes

• Access Catchment
  • Public health and education. Hospital service areas, ambulance-response polygons, vaccination-clinic catchments, and school-attendance zones are defined over the actual network rather than Euclidean radius, with equity analysis comparing catchment populations by demographic.

    This sourceIntroduces the two-step floating catchment area (2SFCA) method computing health-service catchments over the actual travel network and comparing catchment populations for equity, the standard public-health catchment instrument.

    Supported in partVerified against the work's full text

    Luo and Wang define physician catchments from road-network travel times rather than straight-line distance, for primary care only; equity by demographic is explicitly left to future work, and ambulance and school zones are absent.

    “Unlike most of prior work using straight-line distances, this research uses travel times to measure the spatial barrier between residents and physicians.”

Verification

Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.

Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
