Mobility Real-Life Data Collection Use Case

Climate-Neutral & Smart Cities Mission

The City's Data Pulse

Every day, thousands of vehicles reveal how Thessaloniki really moves.

The City's Data Pulse

The RAISE Suite Mobility Use-Case turns this real-time flow into open, FAIR-by-design research data, built on Thessaloniki's Smart Mobility Living Lab, operational since 2008.

At a glance

Pilot Period

M6 – M40

(Feb 2026 – Dec 2028)

Partners Involved
Domain

Mobility / Smart Cities

Location / Study Sites

Thessaloniki, Greece

Participants / Scale
  • 43 Bluetooth sensors
  • 1,000+ taxis
  • passive participation (city drivers)

Main Goal

To collect and analyze real-life urban mobility data through passive monitoring of city drivers, supporting sustainable smart city planning.

Domain Challenges

  • Varied and heterogeneous data sources (passive IoT sensors, public transport feeds).
  • Privacy and ethical standards when collecting data from city drivers without active participation.
  • Dynamic urban environments requiring continuous adaptation of data relevance and quality.
  • Long-term data quality assurance and reusability for urban planning and policy.

Use Case Implementation Phases

May–December 2026
Data Collection Without RAISE
Real-time mobility data flows continuously into the Living Lab from two heterogeneous sources: GPS traces from ~1,000 taxis (updated every minute) and travel times from 43 Bluetooth sensors (updated every 15 minutes). All data passes internal quality control before publication.
May–December 2026
January–March 2027
SDK Integration & RAISE Onboarding
The RAISE Suite SDK is integrated into the CERTH-HIT central data collection hub, enabling FAIR-by-design ingestion of both live data streams — the key demonstration of how existing smart city infrastructure connects to the RAISE Suite platform.
January–March 2027
From March 2027 onwards
Data Collection with RAISE and FAIR Dataset Publication
Both datasets (fcd-gps and datafusion-traveltimes) are streamed through the RAISE Suite platform and registered as FAIR datasets on the RAISE Suite Portal and EOSC-RAISE Certified Nodes (RCN), making them discoverable and reusable by the wider research community.
From March 2027 onwards

Use Case Outcomes

Rich Mobility Datasets

Granular Flows, Speeds and GPS Traces

Deep datasets combining vehicle flows and speeds from Bluetooth detectors with GPS traces and utilisation rates from 1,000+ taxis across Thessaloniki.

Data-Driven Insight

Monitoring and Analysis for Smarter Planning

These datasets power data-driven monitoring and analysis of urban mobility, contributing to sustainable smart city planning across Thessaloniki.

Sustainable Mobility Impact

Greener Journeys, Better Public Transport

Insights support sustainable mobility initiatives — making public transport a more appealing alternative to the private car.
