Methodology · scoring
Transport score
Access to rail, metro and public-transport job clusters from this neighbourhood's centroid.
Formula
The maths
transport = 0.40·rail_access + 0.20·metro_access + 0.40·pt_jobs_access
Weights
Why each input gets the weight it does
| Input | Weight | Rationale |
|---|---|---|
| Rail walk-time | 40% | Walking distance to the nearest National Rail station, capped at 30 minutes (≈2km). |
| Metro walk-time | 20% | Walking distance to the nearest tram, tube, light-rail or metro stop. |
| PT jobs access | 40% | Public-transport time to areas with 5,000+ jobs (DfT Journey Time Statistics methodology). |
Data sources
What feeds this score
- OS National Rail station fileStation-level + local-area centroid
- TfL Open Data (London) + OSM Overpass (regional metros)Stop-level
- DfT Journey Time Statisticslocal area → key services
Limitations
What this score doesn't capture
- The score doesn't yet account for service frequency or off-peak coverage — a station with one train per hour scores the same as a station with twelve.
- Bus access is implicit in the DfT JTS public-transport job access; we don't surface a standalone 'bus' metric.
