Abstract

A method of controlling a traffic system having a plurality of intersections with switchable traffic lights and road sections located between the intersections includes detecting traffic loads of multiple relevant road sections, determining a local stress function for each relevant road section depending on the detected traffic load of the respective relevant road section, determining a global stress function for the entire traffic system based on the local stress functions, determining, using a quantum concept processor, improved switching times for the traffic lights of the intersections adjacent to the relevant road sections, wherein the improved switching times are determined such that the global stress function reaches a smallest detectable value, and switching the traffic lights according to a switching model based on the improved switching times.
