Researchers from an Information and Communication Technologies research group of Technical University of Cartagena have developed a device which is a self-managing system capable of making decisions by itself, without the need to use a centralized computer system, reducing the average waiting time at the intersection by the drivers.

 By means of this control system for self-regulated traffic lights it is possible to reduce the average waiting time at the intersection by the drivers, as well as to reduce the emission of polluting gases into the atmosphere.

 The control system for self-regulated traffic lights comprises:

 A first subsystem of traffic data acquisition comprising means for knowing the number of vehicles and occupants of vehicles, so that not only the traffic density but the density of persons in real-time traffic is known, which may affect to a great extent and is a great differentiator with respect to other proposals;

A second optimization subsystem that appropriately adjusts the cycle times and the different phases that configure the traffic lights that regulate the intersection by means of a probabilistic method able to predict if there is an incipient congestion and to act before it in an autonomous way;

 A third wireless communication subsystem between intersections, resulting in a system not only autonomous but also distributed for the regulation of traffic in a city.


The device reduces the average waiting time at the intersection by drivers, as well as reduce the emission of gaseous pollutants into the atmosphere.


Among the advantages over other alternatives are a much lower processing load than other proposals with equal or higher efficiency, which facilitates their implementation and deployment in real systems, and the ability to self-adjust without the need for human intervention, or with a minimal intervention from an operations center.


Current research interests of the research group include intelligent systems and security provisioning in telecommunications networks, as well as Quality of Service (QoS) and Quality of user Experience (QoE).


Researchers are looking mainly for Information and Communication Technologies Companies and Research Institutions to develop the device by License Agreement of the patent. The research group is also interested in all kind of Research and/or Technical Cooperation Agreement to develop this device and the research results obtained.
