Tampere tests intelligent outdoor lighting control system

Anonymous traffic data from Telia and the Tampere.Finland mobile application were deployed to find out locations where most light is required in the city.

The Finnish city of Tampere has carried out a pilot project to make outdoor lighting smarter and more energy efficient by using traffic data.

 

Joint winners of the Enlighten Tampere hackathon, Arcventure, Geniem and Remod, combined their ideas to arrive at a new way to control streetlights by connecting different virtual or physical sensors sensors to the outdoor lighting control system.

 

Anonymous traffic data

 

The aim of the pilot was how to improve illumination in the city’s busiest areas. Anonymous traffic data from Telia and the Tampere.Finland mobile application, developed by Geniem, were deployed to find out locations where most light is required. The real-time API solution was provided by Arcventure.

 

Although crowd insights service resulting from Telia’s Smart Tampere collaboration have previously been utilised in areas such as urban planning and public transport planning, according to city authorities, this was the first occasion that traffic data has been used to control urban infrastructure.

 

In addition to the traffic data, use of Tampere’s 3D city model was tested in the lighting control. Remod’s idea was to control the lights with a 3D model relative to the time when shadowed areas would each receive more light than bright areas.

 

The intention was that the solution would enhance the ‘intelligence’ of the lighting especially at sunrise and sunset. In the solution, the data is filtered through the calculation and converted into a spotlight value for streetlights.

In August 2019, the functionality of the controls was initially tested where it was discovered that the solution needed to be further refined. The lighting control system of the city’s IoT test area is still under development and has not previously been linked to external controls.

 

“We actually did a pilot inside a pilot,” said Maarit Vehviläinen, project manager, from the city of Tampere. “That has brought its own challenges to implementation and schedules.”

 

During the remainder of the year, the city and the companies will ensure that the external controls function within the system. The results of the pilot will also be utilised when it comes to the acquisition of the IoT platform, outdoor lighting control system and urban scene sensing.

 

The pilot project is part of the Stardust and 6Cities IoT projects. Stardust has received funding from the European Union Horizon 2020 research and innovation programme. City IoT is a 6Cities project funded by the European Regional Development Fund.
