Smart traffic systems use advanced technology to improve the flow of vehicles on the roads. They rely on sensors, cameras, and data analysis to monitor traffic conditions in real-time. By adjusting traffic signals and providing information to drivers, these systems help reduce congestion and minimize travel times. Additionally, smart traffic systems can communicate with connected vehicles and mobile apps to offer route suggestions and alerts about accidents or road closures. This not only enhances safety but also promotes more efficient use of public transportation and encourages eco-friendly driving habits, ultimately leading to cleaner air and less pollution.
