Smart City Lighting

Smart lighting can significantly contribute to economic growth and sustainability in a city by offering
energy efficiency and cost savings through technologies like LED lighting and motion sensors.
Enhanced safety and security from well-lit public areas attract more visitors and residents, supporting
local businesses and nightlife economy while promoting sustainable urban development. Smart
lighting also acts as a catalyst for broader smart city projects, attracting investments and fostering
innovation in related sustainable sectors.

Copenhagen has deployed an intelligent lighting system that uses ICT to adjust street lighting
based on real-time traffic data and pedestrian movement. The smart lighting infrastructure saves
energy by dimming lights when areas are less busy and brightening them as needed. Additionally,
the city employs ICT to optimize traffic flow, reducing congestion and emissions through real-time
data analysis and adaptive traffic signal control.
