IS&SD has developped CHAOS™, vehicle density based adaptive signalized junction management system. CHAOS™, includes video cameras to obtain vehicle density data using digital image processing techniques all of which are developped by the company itself. System, then, manages the signalized junctions to minimize the average waiting time of the vehicles. (shorter green light to less dense direction and longer to more dense one) CHAOS™, more than managing an isolated signalized junction autonomously, can manage a number of junctions simultaneously, known as signal coordination. CHAOS™, is proved to be %42 more efficient when compared to fixed time signal management.
