RTR 4/2010 40 Upgrading Information and Communication Technology systems in Victoria (Australia) Fig. 4: Service Planning, Management and Repor ting relationship Fig. 5: Metro inter faces and relationships selection and management of CIS assets. By setting out the key factors that need to be considered the future systems are optimised and the information will be shared between systems to improve service quality. The strategy presents public transport CIS assets in the context of an integrated multi-modal network. Choice of technology for individual systems needs to be considered in light of the whole network rather than taking a narrow system-centric view. These principles have been applied to the business needs, resulting in a program of CIS development priorities for the next decade. The Public Transport CIS Strategy gives practical advice and identifies pitfalls to avoid when specifying and procuring new technology. The CIS Strategy identifies that planning of services is the most important input to operating passenger services as it sets basic operational targets such as service frequency, travel times, stopping patterns and synchronisation times for modal interchanges. The strategy also identifies that the real-time control of operational services is critical in terms of delivering services, satisfying safety expectations, managing performance against the planned schedule and satisfying customer expectation, which requires a high level of integration and coordination between the various operational control systems. The relationship between planning and service control are shown in Fig. 4. 3 Tasks of the operational control and business information systems Operational control systems are characterised as those systems which process data (including voice) in ‘real-time’ and generally comprise both hardware and software. Control systems support a broad range of public transport functions, ranging from the planning, monitoring and control of passenger services, to the provision of passenger security systems and information displays in vehicles and at stops and stations. Operational control systems typically have a reliance on reference information about infrastructure and assets comprising the public transport network (including rolling stock and vehicles). The asset management systems that record characteristics about infrastructure and assets are also considered to be a part of the control systems family. The Public Transport CIS Strategy identifies that timetabling and the planning of services as important input to operating passenger services and systems supporting these functions are therefore regarded as operational control systems and not business information systems.
