OCCs are central to metro operations, through monitoring the entire system and hosting critical decisions during service interruptions. Several metros report plans to upgrade, expand or integrate aspects of their OCC management to improve the level of service they can deliver. The study detailed the role of OCCs focusing on changes in that role brought about by technological advances.
There is a clear trend towards the centralisation of OCC organisational structures with the belief that a unified OCC will improve the efficiency of coordination and cooperation. One critical function of OCCs is serving as a data management centre. Therefore how often information is updated is key to collecting real-time data for OCC management and communications.
Real-time data management and station remote control technologies are emerging trends and identified areas of improvement. These are often linked with the introduction of greater automation. Increased levels of automation and remote control tend to reduce the routine workload on UTO lines. This means that UTO lines typically require fewer staff in daily operation but more experienced staff to handle incidents.
