Advanced traffic control systems are designed in a manner so they could effectively and efficiently manage traffic flow and contribute towards the realisation of the primary goal of a traffic system which is safety. Various technologies, together with advanced ITS solutions like managing speed limits, on-trip passenger information and managing the in flow assist greatly with solving traffic problem like traffic congestion, incidents, environmental pollution, waiting time, etc. Examples of implementation of advanced traffic management systems are taken from european systems, while the analysis taken from existing systems in Croatia. The paper displays the concept of cooperative management of urban traffic systems. The advanced traffic control system itself is based on the european ITS architecture.
