Feb 6, 2017: Hampshire, UK, has installed smart LED streetlights that alert local authorities to grit frozen roads. The new streetlights have embedded smart control central management system, which can monitor the weather and road surface temperatures, and tell local authorities when to clear the roads covered with snow.
Local authorities usually send out gritting wagons based on weather forecasts provided by the Met office. But these forecasts are not always accurate.
On the other hand, the smart streetlights can monitor the localised road surface temperatures, and send information to local authorities.
Amey, which takes care of the maintenance of highways, has launched the project in partnership with Hampshire County Council and Mayflower, which developed the control management system.
A solution has been developed 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 reads the road surface temperature with the help of infra-red technology. The street lighting network is then connected with the help of Wi-Fi, and the data is passed in real-time to a cloud system.
