Services in Road Traffic Management Systems

This paper outlines the approach to controlling large networks in Traffic Management (TM) Systems also called Active Traffic Management (ATM) for road traffic. In Traffic Management there is an important distinction between local- and network-control systems. The local systems, such as traffic light control in charge of one crossing, or a ramp metering device in charge of one on ramp, are most common. These systems are acting only on local problems. They cannot deal with the effects on the scale of their network or anticipate future traffic conditions. And even worse they may solve a congestion problem within their own scope while creating a problem in an other section of the network. TM systems are essentially systems to coordinate local control systems within a network. Although a number of these TM systems are commercially available, they are not widely used by traffic management authorities. This is mainly caused by the incompatibility of Traffic Management systems. Compatibility and standardization issues play an important role in Network Management systems. These systems cover only a part of a network. Information about neighboring parts of the network is highly relevant. A system needs to receive this information from neighboring control systems. Therefore it has to communicate and to be compatible with other systems. Even within its own scope, it has to communicate with the local systems that were present before the installation of the Network Control systems as a subset of Network Management and deal with influencing streams of traffic. So also for local systems interfacing and compatibility issues are relevant.
