Cooperation in traffic management and traffic information

Traffic management acts as a roof application for various traffic-related systems. A Traffic Management System (TMS) integrates these systems into a single application allowing either the direct control or the generation of control recommendations to the various subsystems from a centralized source. Traffic management thereby provides the basis for cross-system traffic strategies and for the distribution of traffic information. The value chain for integrated traffic management and traffic information has to be built by traffic data collection from various sources, the data qualification, aggregation and completion, the intelligent processing of traffic data, and the use of the real-time traffic situation as well as the traffic forecast estimation for traffic management and traffic information requirements. Some European project examples, based on Public-Private-Partnership (PPP), illustrate the responsibilities shared by the involved parties. Joint forces given by PPP projects leverage the deployment of TMS and traffic information services. The responsibilities allocated to the parties have to be well-regulated in the project contracts.
