{"name": "Izochrony AZO (PSP)", "package_name": "azo_izochrony", "description": "Drive-time service areas (isochrones) for fire & rescue units \u2014 offline network analysis (Dijkstra + decreasing buffer), no API. (PL: izochrony czasu dotarcia jednostek stra\u017cy)", "about": "Adds Processing algorithms for fire & rescue accessibility (\"AZO\"): time-to-arrival-on-scene zones = turnout/dispatch time (per unit type, e.g. professional 3 min / volunteer 10 min) + driving along roads (speed by road class from an in-dialog table \u2014 no network preparation) + off-road approach. Method: graph + Dijkstra (minimum time to the nearest unit) + a DECREASING BUFFER (radius shrinks with the remaining time budget, with a hard R_max), densified along the network and optionally clipped by barriers (rivers, railways, water bodies). Single super-source Dijkstra \u2014 fast even at region/province scale, run in a background thread via Processing (responsive GUI, progress bar, cancellation). Also computes a population-coverage indicator on demand points. Fully offline, no API keys \u2014 suitable for sensitive emergency-service data. Built around the Polish State Fire Service (PSP) and volunteer units in the national rescue system (OSP-KSRG), but applicable to any region. Indicative/educational material; for official use substitute an authoritative road network (e.g. BDOT10k) and official unit data.
