CityPulse Smart City Datasets (Aarhus and Others)

Overview

The CityPulse Smart City Datasets collection provides multiple real-world data streams from smart city deployments, primarily in the city of Aarhus, Denmark, gathered in the EU CityPulse project.[web:111][web:114][web:116]

Key Data Streams

• Vehicle Traffic: Flow measurements between sensor pairs at 449 observation points over several six-month periods, with data available in raw CSV and semantically annotated formats.[web:111]
• Parking Data: Occupancy information from eight parking lots in Aarhus over about six months, including metadata about lot locations.[web:111]
• Weather Data: Meteorological observations for Aarhus (and Brasov) over multiple periods, again available as raw and annotated datasets.[web:111][web:114]

Structure and Formats

• Data are organized as separate CSV files for each stream, with additional RDF/Turtle files providing semantic annotations using the CityPulse information model.[web:111][web:116]
• Traffic, weather, pollution, parking, and event datasets can be downloaded either as combined archives or individually via the web interface.[web:111]

Use Cases

• Urban computing and multi-source data fusion across traffic, environment, and events.[web:111][web:114]
• Smart city services such as congestion prediction, parking recommendation, and context-aware applications.[web:111][web:110][web:116]
• Semantic IoT research using annotated data streams and Linked Data models.[web:111][web:116]
