liiklusandmeid

Liiklusandmeid refers to the collection, analysis, and dissemination of traffic data, primarily used in Estonia to support city planning, transportation management, and public safety. The term combines the Estonian words for traffic (liiklus) and data (andmeid). Traffic data can include vehicle counts, speeds, travel times, incident reports, and patterns of congestion. It is gathered through a variety of sensors, such as inductive loops embedded in roads, radar and laser speed sensors, and cameras equipped with automatic number plate recognition. Mobile phone positioning data and GPS traces from navigation devices also contribute to real‑time traffic monitoring.

The Estonian government, through the Ministry of Economic Affairs and Communications, coordinates national traffic data initiatives. Data is shared with municipal authorities, emergency services, and public transport operators. The National Institute of Natural Resources (NPNR) publishes periodic reports and provides access to traffic statistics through online portals. The City of Tallinn, for example, uses real‑time traffic feeds to manage adaptive traffic signals and to inform commuters via mobile applications.

Privacy concerns are addressed by anonymising personal identifiers. The General Data Protection Regulation (GDPR) and national laws govern the handling of data, limiting the use of personal vehicle information to aggregated statistics. The Tallinn Mobility Forum and other stakeholder groups discuss how to improve data quality, integrate multimodal transport information, and promote sustainable mobility. Overall, Liiklusandmeid plays a crucial role in creating safer, more efficient, and environmentally friendly transportation networks in Estonia.
