Gran Canaria’s smart highway is Dark Sky compliant

A motorway with street lights and lots of traffic
The lighting on Gran Canaria’s main motorway is both internet-connected and ‘Dark Sky-compliant’, and features a popular colour temperature of 2700K.

A STATE-OF-THE-ART traffic lighting system has been unveiled onGran Canaria’s main motorway.

It’s internet-connected and ‘Dark Sky-compliant’, and features a popular colour temperature of 2700K.

The new installation also features an energy saving of 80 per cent compared to the previous system.

The local authority says the lighting of the GC-1, the island’s most important highway, preserves the outstanding conditions for viewing the night sky as required by the Canarian Observatories. 

It also helps to respect the island’s biodiversity and reduces CO2 emissions and the island’s carbon footprint without compromising road safety and driving experience. 

The new lighting has already resulted in positive reactions from road users, who report having a better driving experience.
The Gran Canaria South Highway (GC-1) connects the island’s capital Las Palmas de Gran Canaria and its international airport to the tourist destinations on the south side of the island. 

The highway was illuminated in 1990 with the Philips Traffic Vision streetlights. 

As the luminaires reached the end of their lifetime, the island’s council seized the opportunity to improve lighting performance and reduce energy consumption. 

Highway engineers specified Philips DigiStreet LEDs with Interact City connected lighting software. 

With Interact City, the Cabildo de Gran Canarias can monitor the lighting in real time, collect and analyse data, and assign maintenance tasks to technicians. 

The low-glare luminaires improve visual comfort and improve the uniformity of light distribution.
The system allows for planned maintenance, point-by-point management and enables real-time adjustment to deal with any situation on the highway. 

For example, increasing light in an area where an accident has occurred or dimming the lights to 30 per cent when no vehicles are on the road. 

The street lighting system can also offer the council new connected capabilities as time goes on. 

Another important aspect of the project was the local regulations concerning the night sky. 

The Canary Islands have the darkest skies in Europe, offering exceptional conditions to observe the stars and hosting several internationally renowned observatories. 

The luminaires had to comply with the regulations of the Instituto Astrofísico de Canarias (IAC) and the Light Pollution Regulation for the Canary Islands.

‘We have developed a clear and sustainable project for our lighting system. It’s a major revolution in energy efficiency and cost savings,’ said Antonio Morales, President of the Cabildo de Gran Canarias, told Lux. 

‘Upgrading to this system gives us economic savings of installed power with 50 per cent, amortising the cost of installation in less than the luminaires’ lifetime.’
