Efficient urban mobility is essential for modern cities, but it remains a significant challenge. WISP, an AI-driven traffic management solution, aims to tackle this issue by optimising traffic lights without requiring additional hardware. This innovative system leverages real-time data from connected vehicles to improve traffic flow, reduce waiting times, and cut emissions. Costly and inefficient traffic systems / The lack of information on road flows poses significant challenges for public and local authorities in addition to the considerable economic, environmental, and societal costs caused by traffic congestion.
