US Patent 11482103 Control and manage traffic light system with VANET

The programming of traffic lights systems (TLS) in cities is a complex optimization problem. The main problem of the actual process is that this is a long, expensive and imprecise process that must be repeated regularly to reflect changes in traffic flow. The invention consists of using Vehicular's ad hoc networks (VANET) to collect traffic data in real time and transmit them to a traffic management system. VANET is currently defined by the IEEE 802.11p standard. We propose to use VANET in correlation with others techniques to control TLS. This invention will permit to program actual TLS more efficiently, manage a network in real-time and it will be possible to be used for urban planning studies, transport planning or to simulate the exit of special events (sporting, cultural, parades, etc.). It also allows programming TLS in real time with any efficient algorithm that exists or to be developed.
