The Challenge

Cities across Europe face mounting challenges driven by urbanization, climate change, and increasing demand for smarter, more efficient infrastructure. Key concerns include traffic congestion, retail downturns, real estate vacancies, safety during large events, and the need for sustainable development, all of which require timely and actionable insights. Traditional planning methods often fall short in providing the real-time data necessary for smart decision-making.

The Solution: Ariadne’s Smart City Analytics Platform

Ariadne offers a powerful analytics solution designed for cities, retail districts, and public venues. By combining advanced movement tracking technologies with real-time data processing and visualization, Ariadne enables municipalities and their partners to:

• Measure pedestrian frequency using GDPR-compliant anonymous data
• Visualize movement through heatmaps and dashboards for actionable insights
• Monitor events and traffic flows in real-time for safety and efficiency
• Integrate with smart city platforms like Frankfurt’s UDP for live control and analysis
• Optimize marketing, real estate planning, and infrastructure management

Technologies used include WiFi tracking, LiDAR, RFID, beacons, and sensors, all installed cost-effectively and non-invasively across public and private spaces.
