MediaTransports, leader in transport advertising

A subsidiary of the Publicis Group, MediaTransports is the main operator of advertising spaces in French public transport (subway, buses, railway stations). Through its entities Metrobus and Mediagares, the company connects brands with millions of commuters every day.

The Challenge: Regulatory compliance & energy performance

Following the Energy Resilience Law (August 22, 2021), which mandates the night-time shut-off of illuminated advertisements, MediaTransports needed to rethink the management of its installations. Objectives:

  • Strict compliance with regulatory schedules.

  • Reduction of energy consumption and carbon footprint.

  • Remote management of a fleet distributed across vast geographical areas.

Without automation, manual management would have generated significant operating costs and complex compliance processes.

The Answer: An IoT solution designed for efficiency

DFM-Europe, in collaboration with Orange Business, designed a tailored IoT solution incorporating connected sensors and a supervision platform. RSO technology enables:

  • Centralized and automated control of switching on/off cycles.

  • Immediate reduction in energy consumption.

  • Proactive alerts in case of malfunction.

  • Real-time visibility across the entire fleet.

The Results: More control, less consumption

  • Regulatory compliance guaranteed across the entire fleet.

  • Significant reduction in energy costs.

  • Measurable reduction in CO₂ emissions.

  • Improved operational efficiency, with fewer on-site interventions.

  • Enhancement of MediaTransports' image as a responsible and committed actor.

The technology behind the success: RSO

RSO is our intelligent energy management system:

Key features: 

  • Real-time tracking of consumption. 

  • Remote management via an intuitive interface.

  • Automatic optimization of activation schedules. 

  • Data analysis for strategic recommendations.

With RSO, MediaTransports controls, optimizes, and anticipates, all while aligning with a sustainable energy transition approach.

National recognition

This project was awarded at the IoT Business Hub 2024 in the Energy Management category, confirming the tangible impact of our solution on environmental and operational performance.
