Kollektivtrafikdata

Kollektivtrafikdata is a broad term for data related to public transportation systems. It includes static information such as networks, routes, stops, schedules, and fares, as well as dynamic information like real-time vehicle positions, estimated arrival times, disruptions, and service alerts. The data supports journey planning, timetable management, performance analysis, and the development of travel applications.

Data sources typically include transport authorities and operators, and it is made available through public portals and APIs. Common data components are route definitions, stop locations, timetable data, and real-time feeds. Many implementations follow international standards for interoperability, such as GTFS for static schedules, GTFS-realtime for live updates, and exchange formats like NeTEx or SIRI.

Access to kollektivtrafikdata is often provided as open data under permissive licenses, enabling developers, researchers, and planners to reuse the information. Some portals require registration or API keys, and terms of use may specify restrictions on commercial use or redistribution.

Applications of kollektivtrafikdata include consumer journey planners, mobile and web apps, digital signage, and academic research. Authorities use the data to monitor network performance, assess coverage and reliability, and inform planning decisions about service changes or investments.

Governance and challenges include variable data quality, coverage gaps, and timeliness across operators. Harmonization of data formats and licensing remains an ongoing effort to improve interoperability. Privacy considerations apply to any usage of passenger-related data, particularly when combining datasets for analysis.

In Sweden, Trafiklab operates a national portal for kollektivtrafikdata, hosting ResRobot APIs and related datasets to enable open access and standardized data sharing across regions and operators.
