The four components behind every neighbourhood's Walkability rating — sidewalks, points-of-interest density, transit access, and the tropical-heat-and-shade factor most walkability indexes ignore — plus the formula, data sourcing, and honest limitations.
The short version: Walkability is scored 0–10 from four equally-weighted components — sidewalks & pedestrian infrastructure, POI density, transit access, and heat & shade coverage — then feeds into the wider 9-factor BAANLYY Area Score as its own Walkability factor.
Each neighbourhood's Walkability rating is built from four equally-weighted components, scored editorially and averaged into a single 0–10 figure.
| Component | Weight | What it measures |
|---|---|---|
| Sidewalks & pedestrian infrastructure | 25% | Whether continuous, usable sidewalks exist along an area's main routes — width, surface condition, obstructions (parked motorbikes, vendor stalls, utility poles) and the presence of covered walkways or skybridges linking buildings |
| Points-of-interest (POI) density | 25% | How many everyday destinations — convenience stores, restaurants, pharmacies, markets, cafés — sit within a genuinely walkable distance of a typical residence in the area, not just how many exist somewhere in the district |
| Transit access | 25% | Proximity to BTS/MRT stations, bus stops or piers that are themselves reachable on foot, since a neighbourhood with great sidewalks but a 20-minute walk to the nearest station is only half walkable |
| Heat & shade coverage | 25% | How much of a typical walking route is shaded — tree cover, covered arcades (like Bangkok's classic shophouse walkways), skywalks and building overhangs — because in Thailand's tropical heat, an unshaded sidewalk is often functionally unwalkable at midday even if it's physically well-built |
Walkability (0–10) = average of the four component ratings above, each weighted equally at 25%. That single 0–10 figure is what appears as the "Walkability" factor inside the wider 9-factor BAANLYY Area Score (see the full Area Score methodology for how all nine factors combine into a neighbourhood's overall 0–100 score). No component is secretly weighted more than another in the default score.
Most walkability frameworks were built for temperate-climate cities and treat shade as cosmetic. In Thailand, ambient temperatures regularly exceed 33–35°C in the hot season (roughly March to May), and an unshaded sidewalk that is otherwise perfectly serviceable can become a genuinely unpleasant or impractical route to walk at midday. BAANLYY's methodology weights tree cover, covered arcades (the classic Bangkok shophouse walkway), skywalks and building overhangs as a full, equal component precisely because ignoring climate would misrepresent how walkable an area actually feels to someone living there day to day, not just how it would score on paper.
