TRANSPORT & TRANSIT CONNECTIVITY METHODOLOGY
Transit Proximity & Connectivity Index
We calculate transport accessibility by measuring proximity to railway stations, London Underground lines, bus stops, and EV charging points using OpenStreetMap and NaPTAN datasets.

Transport Score Breakdown
| Score Tier | Transit Characteristics |
|---|---|
| 9.0 – 10.0 | Underground or major rail hub < 500m; frequent urban bus network. |
| 7.0 – 8.9 | Railway station < 1.5km; multiple bus stops within 5-minute walk. |
| 5.0 – 6.9 | Suburban bus routes nearby; nearest station 2km – 5km. |
| 1.0 – 4.9 | Rural location; car dependency; nearest station > 5km. |
Important Technical Limitations
- Straight-Line Distances: Proximity is calculated as Euclidean/Haversine distance from centroid; pedestrian walking routes may differ.
- Timetables Not Modeled: We measure physical infrastructure presence, not live timetable service frequency.
Data Attribution
