Efficient traffic management in urban areas remains a significant challenge as vehicle density grows and infrastructure ...

Red and green traffic lights have been around since the 1800s, when British traffic officers used to rotate gas lamps that burned red and green to control the movement of mostly horse-drawn vehicles.

Many red lights fail to detect smaller vehicles like bikes and scooters due to sensor limitations. Inductive loops, common in traffic signals, rely on sufficient metal mass to register a vehicle.
