liikennetietopalvelut

Liikennetietopalvelut refers to a set of services that collect, process and disseminate information about traffic and transport conditions to support safe and efficient mobility. They cover real-time traffic data, incidents, roadworks, closures, weather-related conditions, and travel time estimates for motorways and local roads, as well as public transport status.

Data sources include road sensors, cameras, vehicle probe data, public transport tracking, crowdsourced reports, weather data, and planned works schedules. Data is produced by national and local authorities, road operators, and private providers, and is often shared through standardized formats to enable interoperability.

Deliveries channels include online portals, mobile apps, in-vehicle navigation systems, APIs for developers, and road-side dynamic signs. In Europe, common data formats and exchange standards such as Datex II and GTFS-realtime are used to enable integration across platforms.

Users and uses span individual travelers and fleets who rely on up-to-date routing and travel times, traffic managers who monitor conditions and coordinate responses, and planners who analyze trends for infrastructure and service planning. Public transport operators also use traffic information to adjust schedules.

Governance and access are typically managed by national authorities or designated agencies; in Finland, Liikennetietopalvelut dataflow involves Traficom and Väylävirasto, with open data portals and licensing that encourage reuse while respecting privacy and safety requirements. Open data and standardized interfaces aim to support innovation in navigation, travel planning, and transport research.
