A transparent framework for comparing Thai neighbourhoods on transit access: four equally-weighted sub-factors — station proximity, line frequency & reliability, multi-modal connectivity and network reach — each scored 0–25 for a 0–100 total, benchmarked against Bangkok's BTS, MRT, ARL and SRT commuter-rail network.
Status, upfront: this page defines the Transit Score methodology in full detail. A single simpler 1–10 "Transit" rating is already live inside the BAANLYY Area Score for every neighbourhood. This four-factor, 0–100 breakdown is the disclosed framework for a more detailed version — not yet computed and published per area. We say so plainly rather than implying a score that doesn't exist yet.
| Sub-factor | Points | How it would be measured |
|---|---|---|
| Station proximity | 0–25 | Walking distance and time to the nearest BTS, MRT, Airport Rail Link (ARL) or SRT commuter-rail station. Sub-500m / under-7-minute walks score highest; areas requiring a motorcycle taxi or songthaew feeder trip score lower. |
| Line frequency & reliability | 0–25 | Typical peak and off-peak train frequency on the nearest line(s) — BTS Sukhumvit/Silom and MRT Blue generally run every 3–5 minutes at peak and 5–10 minutes off-peak, versus SRT Dark Red/Light Red commuter lines which run less frequently. Service hours and general on-time reputation are also weighed. |
| Multi-modal connectivity | 0–25 | Whether the area sits at or near an interchange between lines (e.g. Siam, Asok/Sukhumvit, Mo Chit/Chatuchak Park), and how well it connects onward to buses, the Chao Phraya Express Boat, ride-hailing and, increasingly, bike-share and e-scooter parking. |
| Network reach | 0–25 | How many major destinations — CBD office clusters, malls, hospitals, universities, and the airports (Suvarnabhumi via ARL, Don Mueang via SRT) — are reachable within roughly 30–45 minutes and one or fewer transfers from the area. |
Transit Score = Station Proximity (0–25) + Line Frequency & Reliability (0–25) + Multi-modal Connectivity (0–25) + Network Reach (0–25), for a maximum of 100. All four sub-factors are equally weighted by default, the same disclosed, equal-weight approach BAANLYY uses for its Investment Score and Neighborhood Score — every BAANLYY score follows the same transparent-methodology principle, even where the specific factors differ by purpose.
Bangkok's urban rail network spans the BTS Skytrain (Sukhumvit, Silom and Gold lines), the MRT (Blue, Purple, Pink and Yellow lines), the Airport Rail Link connecting the city to Suvarnabhumi Airport, and the SRT Dark Red and Light Red commuter lines serving the northern and western suburbs. Frequency varies by line and time of day — the core BTS and MRT Blue lines generally run every few minutes at peak and somewhat less frequently off-peak, while commuter-rail lines run less often. An area's Line Frequency & Reliability sub-score is set relative to which of these networks actually serves it, not a single city-wide average.
Two areas can both sit 300 metres from a station and still offer very different transit value. An interchange station such as Siam, Asok/Sukhumvit or Mo Chit puts multiple lines, bus routes and — at Sathorn — the Chao Phraya Express Boat within reach of the same address, while a single-line station further from an interchange offers less onward flexibility. Splitting Multi-modal Connectivity and Network Reach into their own sub-factors captures that difference instead of treating "near any station" as interchangeable.
