Hong Kong–Shenzhen Index Method, Sample Size and Anonymous Data Note
Verified public data: This edition uses 230 daily observations for five control points, one live status snapshot and 2024 category totals for five road crossings; these are not trip-level vehicle-time samples.
Sample / Collection period
| Data layer | Sample | Collection period | What it answers |
|---|---|---|---|
| Daily passenger traffic: 4 Checkpoint + Airport control point | 920 + 230 daily aggregates | 2026-01-01 to 2026-08-18 | Traffic scale and traffic P50/P90 |
| Live status snapshot | 1 | 2026-08-19 22:30 HKT | Public status category at observation time |
| Vehicle category: 5 Checkpoint | 5 annual aggregates | 2024-01-01 to 2024-12-31 | Official vehicle-category counts and shares |
| Vehicle clearance time (minutes), Flight-level delay share, Airport landing-to-driver meeting wait P50/P90, Booking scenario | 0 public trip-level samples | Not publicly published; cannot be computed rigorously | Not publicly published; cannot be computed rigorously |
Percentile definition
Daily passenger trips are sorted by date and P50/P90 are calculated with linear interpolation; the table unit is passenger trips. Vehicle clearance P50/P90 requires valid start/end timestamps within the same checkpoint, direction and date-type layer.
Source layers
- Official daily passenger CSV: reproducible by date and control point, but not a vehicle-time log.
- HKeMobility live status: a status category refreshed about every 15 minutes; it represents the observation moment only.
- Transport Department annual vehicle statistics: aggregated by crossing and vehicle category, without booking scenarios or vehicle configurations.
- HKTDC expo dates: a reproducible event-date layer, not proof of causation.
Anonymisation and privacy
The public aggregates contain no names, phone numbers, plates or order IDs. Any future internal-log release should use random event IDs, time bands and removal of direct identifiers.
A real time index needs anonymised vehicle-level start and end timestamps; passenger counts cannot substitute for them.
