The City of Tartu replaced 320 existing sodium lights in the city centre area of Tartu with energy efficient LED lighting. The new lighting and the traffic and environmental sensors, together with the wireless control units developed by Cityntel OU, form a smart street lighting network.
The City of Tartu aims to increase the overall energy efficiency of city services, which includes installing a smart and energy-efficient street lighting system. LED lights have much greater lifespans and offer considerable energy savings.
Within the framework of the SmartEnCity project, the City of Tartu replaced 320 existing sodium lights in the city centre area of Tartu with energy efficient LED lighting. The new lighting and the traffic and environmental sensors together form a smart street lighting network. Energy efficient street lighting was installed along Pepleri, Pargi, Kuperjanovi, Õpetaja, Tiigi, Vanemuise, Aida, Lao, Kalevi, Tähe, W. Struve, Akadeemia, Kitsas, Soola, Lille, Vallikraavi, Filosoofi, Lootuse, Kastani, Veski, Kooli, A. Haava and Näituse Street, all located within the pilot area of the project.
Cityntel OÜ installed control units in all of the lighting, allowing for the operation of the lighting to be organised remotely. The smart street light control system developed is based on a wireless mesh technology. Smart controllers, capable of network and device-related decision-making, are installed in each of the new 312 LED street lights in Tartu and rely on wireless communication for exchanging information between the controllers and sensors. Unlike competing solutions where all control commands are issued from a server or network controller, this smart control solution requires no permanent…
The smart street light system will be integrated with the City Information Open Platform (CIOP) that has been developed in the SmartEnCity project. The smart street lights send data from luminaires (energy consumption) and sensors to the CIOP for monitoring and analysis purposes. The citizens will also be engaged through the CIOP in the form of a poll that explores the outdoor lighting comfort level. Based on the feedback received from the residents, the brightness level of the street lights will be adjusted.
