The aim of this article is to present the design process of an adaptive traffic light controller for the Rondo Starołęka intersection in Poznań. The work involved evaluating the existing traffic control solution at the intersection, followed by the creation of an original adaptive signaling system, including appropriate phases and a control algorithm. The proposed solution was compared with the existing one using traffic microsimulation with the VISSIM system. After creating a virtual model of the intersection, conducting simulations, and analyzing the results, it was concluded that the newly designed adaptive traffic light system improved traffic conditions at the intersection and significantly reduced vehicle queues at one of the approaches.The increase in the motorization of society has significantly affected traffic conditions in cities. The continuous growth of vehicles on the roads causes the capacity of road sections and junctions to be exceeded, contributing daily to congestion and, consequently, losses, especially in time, for road users.
