An IoT urban traffic network of traffic lights powered by sensors and machine vision to optimize the flow of vehicles and pedestrians.

A network of traffic lights powered with sensors, machine vision, and IoT communication protocols designed to improve traffic interactions between vehicles and pedestrians. Smart traffic lights work by extracting data from sensors, which in turn feed the traffic lights with information regarding pedestrians' speed while crossing the street as well as the daily amount of vehicles circulating at a certain intersection. Also, approaching bikes and vehicles mounted with GPS and wireless connectivity can send signals to traffic lights, thus warning the system to better plan whenever to shutdown a crossroad as the vehicles approach. With the help of machine learning algorithms, the smart lights can understand traffic volume while making real-time changes. This technological solution helps improve traffic flows, besides preventing possible accidents produced by poorly communicated traffic modes.
