02 Core Concept: How the AI works
The system scores each candidate shelter across six factors:
Recommendations are delivered in plain language via RAG (Retrieval-Augmented Generation) — the AI only references verified public data, never inventing facility details.
/ 01
Distance
Walking distance from where you stand
/ 02
Availability
Open now, with a number to call
/ 05
Safety
Avoids senior pedestrian-accident zones
/ 06
Data reliability
How recent and verified the record is
/ 03
Weather fit
Designated heat- or cold-shelter status
/ 04
Transit access
How close the nearest bus stop is

01 Problem Definition
Map apps point to the nearest pin.
For an older resident in a heatwave, a shelter 250 m away can be the wrong choice — closed, with no air conditioning, or across a pedestrian-accident hotspot.
A shelter 430 m away may be the one that actually keeps them safe.
