Street lights that tell local authorities when to grit frozen roads have been unveiled in Hampshire.
The new lamps are fitted with a smart control central management system, which is able monitor weather and road surface temperatures.
A council usually takes the decision to send out gritting wagons, based on weather forecasts provided by the Met Office.
However, these forecasts can be inaccurate and are often based upon large areas, rendering them unreliable when attempting to predict localised temperature levels, which often vary.
The streetlights, however, are able to predict and monitor localised road surface temperatures, producing bespoke information to assist those working on the ground.
Mistakes are often made, with salt either being spread unnecessarily or in the wrong areas.
Gritting orders have increased dramatically this winter, with UK councils ordering an estimated 1.3 million tonnes of salt ahead of the winter gritting almost double the number from last year.
Amey, which provides highways maintenance, launched the project in partnership with Hampshire County Council and Mayflower, which developed the control management system.
Working together, Wintersense, the Met Office, Mayflower and Amey developed a solution to utilise weather station sensors and road surface temperature sensors on a test route in Hampshire, monitoring the temperature on the roads in real time.
Wintersense is an Internet of Things-inspired (IoT) road surface temperature sensor, that use infra-red technology to read the road surface temperature
Then, using Wi-Fi to connect to the street lighting network, the data is passed in real-time to a cloud system.
The weather stations then provide additional information about air temperature, wind speed, wind direction, rain fall and humidity.
Data from the trial route will also be analysed and published so that other local authorities can view it and decide if it would be of benefit to them.
Smart cities will be discussed in detail at this year's Lighting Fixture Design Conference. Mark Cooper of Smart City Advice will consider how manufacturers can best maximise the opportunities that the Smart City revolution offers. The event will be held in London on the 21 - 22 of February 2017 at the Cavendish Centre. You can find out more about the event here and you can register to attend by clicking here.
