Data sources
Our base dataset combines public travel and transport information, operator notices, field checks, and user reports. Instead of relying on a single source, we compare multiple signals to provide more practical guidance.
- We start with official notices and operator information.
- We recheck items that require repeated confirmation.
- Reports are applied after internal review.
Update standards
Information is reviewed regularly, and important changes are reflected as quickly as possible. When something cannot be confirmed immediately, we describe it carefully based on the current level of verification.
- Update timestamps are managed in internal records.
- Unclear information is displayed conservatively.
- Correction requests are reviewed with priority.
