Abstract—Adaptive traffic control system is the latest generation of traffic control systems that operates, manages and control the signalized intersections with/without coordination. ATAK is one of the adaptive traffic control system that is developed by ISBAK Inc., in Turkey. It uses the genetic and fuzzy-logic algorithm as an optimization tool. The genetic algorithm is used for optimizing signal timings and fuzzy logic is used for controlling the exceptional cases during the operation of traffic control devices. This study defines the ATAK system as an traffic management tool at signalized intersections. The performance of the system is outlined. Application of the ATAK system at isolated and coordinated intersection showed that the performance improvement is about 10% in terms of cycle time and travel time improvement is about 15%.
