Abstract
Nashville is quickly growing, and as a result, traffic congestion is becoming a bigger challenge for commuters. Longer travel times and increased vehicle emissions are major concerns. This research examines how smart traffic lights can improve traffic flow and reduce congestion in the city. By analyzing peer-reviewed journal articles, this study explores how AI, IoT, and machine learning can optimize traffic signal timing in real time. In particular, simulation models illustrate how these technologies adapt dynamically to changing traffic patterns in cities similar to Nashville. Furthermore, this research compares the cost-effectiveness of smart traffic lights with other solutions, such as roundabouts, while also highlighting their role in improving pedestrian safety. Overall, the findings suggest that adopting smart traffic signals can improve efficiency, lower emissions, and decrease travel times, ultimately creating a more sustainable and adaptable transportation network to support Nashville’s growth.
