For travellers
- Door-to-door planning. One plan can combine walking, shared bikes, trains and buses, even across operators and borders.
- Better information. Delays and disruptions can reach many apps, not only the operator's own.
- More choice of apps. Open data lets many services compete on quality instead of on who has the data.
For operators and authorities
- Publish once, reached by many. Instead of many separate data deals, data goes to a National Access Point and is available to all.
- Visibility. Services that are easy to find in journey planners are easier to use.
- Common formats. Standards such as NeTEx and SIRI reduce one-off integration work.
For developers and researchers
- A known place to look. The National Access Point and its metadata make datasets discoverable.
- Reusable data. Common formats mean code written for one country can often be reused for another. See how to use transport data.
- Better evidence. Open data supports analysis and policy-making.
For competition and the single market
When data access does not depend on private deals, new and small players can compete with large ones. A shared framework also supports cross-border travel services within the EU single market.
What it takes
The benefits depend on data being accurate, up to date and well described. That is why metadata and licences and good data maintenance matter as much as the legal requirement itself. See how to publish transport data.
