In a pilot project in Finland, anonymous traffic data has been used to make outdoor lighting smarter and more energy efficient.
The joint winners of the Enlighten Tampere hackathon, Arcventure, Geniem and Remod, combined their ideas to develop a new way to control street lights in Tampere’s Internet of Things (IoT) test area by connecting different sensors to the outdoor lighting control system.
In particular, the project explored how to get more light in places where people actually move around. Anonymous traffic data from Telia and the Tampere.Finland mobile application developed by Geniem were utilised to identify locations where the most light is needed.
The real-time API solution was provided by Arcventure.
“In the solution, the data is filtered through the calculation and converted into a spotlight value for street lights,” explained Leo Salomaa from Arcventure.
While crowd insights from Telia’s Smart Tampere collaboration have already been used for urban planning and public transport planning in the city, this is the first time traffic data has been used to control urban infrastructure.
In addition to traffic data, the partners tested street lighting control using Tampere’s 3D city model. Remod’s idea was to enhance the intelligence of the lighting especially at sunrise and sunset by controlling the lights relative to the time when certain areas are in shadow.
The solutions from Arcventure and Remod demonstrate how lighting control can be enhanced by combining information from different sources.
“The more different virtual or physical sensors can be connected to the system, the smarter the lighting,” the City of Tampere said.
During the rest of the year, the city and the companies will work to ensure that external control functions properly within the system.
