Long Beach tests traffic lights that respond to real-time congestion

The city will work with Mercedes-Benz and Xtelligent, deploying a fleet of up to 50 smart vehicles and artificial intelligence software that will communicate real-time traffic data to an intelligent intersection control system. The vehicles will primarily be sharing location data, a common feature in most cars with onboard navigation systems. However, in this case, the vehicles will share data with each other and with city infrastructure.

City planners and engineers will be able to use the shared data to measure traffic congestion and even calculate emissions based on the type of vehicle and distances travelled, city officials said. Data analysis from connected test vehicle fleets and existing physical sensors around the city may also inform future transportation policy and traffic engineering decisions.
