Smart street lighting controls combined with artificial intelligence help the highway authority improve energy efficiency, increase traffic safety, reduce CO2 emissions, and lower operation and maintenance costs

Olympia Odos selects Tvilight’s smart street lighting solution to offer ideal illumination and make the A8 Motorway safer and energy-efficient:


  • Over 200 km highway across Athens-Patras are already equipped with smart controllers (*March 2024)
  • Using Artificial Intelligence, street lights brighten or dim based on predicted traffic and weather conditions
  • LED technology and AI-based adaptive street lighting save up to 75% energy and reduce carbon footprint by 25%
  • The project received the Golden Award in the “Energy Innovation” category
  • Project partners include Sielight for LED streetlights, Vinci Concessions for installation, and Olympia Odos Operations S.A. for operations

Customer Need

An adaptive street lighting system that produces satisfactory outcome

The A8 Motorway (Athens-Patras highway) is one of the most significant projects with strategic importance for the development of the Peloponnese, Western Greece, and Epirus. The motorway connects the three regions and the capital of the country with the most important gate of Greece to Europe, the port of Patras.

Conventional lighting usually results in high energy consumption and a massive carbon footprint. The illumination is also poor with such lighting, compromising road safety and fluidity of transportation system. Plus, the maintenance is always on a higher side. We were aware of these issues and wanted to avoid them altogether for the country’s most important highway,” explained by Olympia Odos S.A., a consortium of six companies responsible for the design, construction, financing, maintenance and operation of the motorway.

With the focus on sustainability, road safety, and environment and the knowledge of the drawbacks of conventional lighting in mind, Olympia Odos searched for an effective smart street lighting solution that could produce satisfactory outcome and decided to invest, above and beyond its contractual obligations, in it.

System Architecture


Cutting-edge IoT street light control system for motorways

Considering it is a motorway, where ideal visibility during different times at night is necessary, IoT-based smart street light control system was selected. It helps adjust the light intensity of LED luminaires to offer the right illumination for improved safety and fluid mobility. It also allows to cut energy waste and CO2 emissions. The openness and flexibility of the system proved to be very beneficial, allowing us to integrate artificial intelligence for adaptive lighting,” explains a spokesperson from Olympia Odos S.A.

Thanks to the easy integration of artificial intelligence in this project, over 7.500 street lights on the motorway brighten or dim based on the predicted traffic, expected weather, and other events on the road, delivering excellent energy savings without compromising road safety. For this unique project, partners include Sielight for LED street lights, Vinci Concessions for installation, Olympia Odos Operations S.A. for operations, and Tvilight for the innovative street light control system.

Currently, the adaptive smart street lighting solution reduces energy consumption by 75% and carbon footprint by 5000 tons annually.
