QUALITY OF SERVICES SOLUTION FOR EFFICIENT COMMUNICATION WITHIN A DISTRIBUTED URBAN TRAFFIC CONTROL SYSTEM

Modern Urban Traffic Control (UTC) systems are based on cooperative entities, able to produce optimal signalling strategies independently of traffic control centres. The more information the junction's entities receive from their neighbours, the more effective the distributed system is. But not all the information is critical. For improving the transmission of data and building an efficient QoS structure, a simplified UTC packet is proposed. This solution can be deployed in any real UTC distributed system for guaranteeing that critical traffic parameters are successfully exchanged between its local decision making units in order to ensure a fully adaptive operation.
