Project description

The rapid urbanization and exponential growth in vehicular traffic have significantly strained traditional traffic management systems, which rely on static control mechanisms like fixed-timer traffic lights. These systems often result in inefficient traffic flow, increased congestion, higher fuel consumption, and elevated carbon emissions. To address these challenges, this paper presents a comprehensive smart traffic light system developed using the Raspberry Pi Pico as the core controller. The proposed system integrates multiple technologies, including sensor integration, real-time vehicle…
