Project Overview 

Aberdeen City Council (ACC) deployed a small-scale demonstrator project for Intelligent Street Lighting by utilising the deployment of LED optical units along a high profile area in the centre of Aberdeen and which was expanded through the ERDF 8th City funding. 

As part of the procurement process an innovative hybrid Central Management System was developed which uses LoRaWan open network gateways to control the nodes on the lighting columns through a mesh network. 

Flood sensors have also been installed and provide data on when interventions are required to prevent flooding which in turn causes disruption. ACC is wiring the new LED lanterns to allow future development and installation of sensors to be connected to the system through the two spare cores in the flex. 

Additionally, the ACC Part-Time 20mph and Safer Routes to Schools have been connected to the system for switching signs on and off at specific times. 

Why is it needed? 

This project has enabled old, inefficient lighting units to be replaced, generating cost and energy savings. The deployment of additional sensors and data collection, contributing to ACC’s ambition to enable a variety of Smart City solutions. 

Impact and Benefits 

▪ Energy consumption has been reduced through more efficient light sources (shown to be up to 60% in comparison to the units they replaced) and consequently reduced carbon footprint. 

▪ There is now adaptive control of the lighting system remotely through the central management system and the system can alert users of any faults as they occur, negating the need to wait for a complaint to come through. 

▪ Data provided by sensor deployment contributes towards having a more resilient city and enhance public safety.
