Traffic-O-Meter is a proposed solution to help address traffic congestion problems by using sensors, the Internet of Things (IoT), machine learning and artificial intelligence to optimize traffic signal timing in real-time based on current traffic conditions. It involves installing nodes with IoT devices at traffic signals that can communicate with a central control room to coordinate signal timing across a smart, connected traffic network. The goal is to save 20-30% of travel time for commuters by reducing wait times at signals.
