1. A complete integrated solution in which movement authority and interlocking are integrated within wayside zone controllers; this reduces equipment and potential interfacing issues. Integrating the management of the interlocking with train location information, as communicated through the CBTC system, allows faster response times, more tightly controlled movements, and easier expandability and adaptability. Interfaces within the zone controller are more easily designed than those between subsystems. The integrated system knows the position of each train to a high degree of accuracy. It can control the behavior of the train at all times and, in response to changing conditions, can modify the behavior to ensure safety of the system while offering maximum service. It can adapt its algorithms to take advantage of individual train behavior, and change parameters to ensure optimum use of resources, such as platform availability and traction power. The limit of movement authority setting logic has a high impact on the end system performance, i.e. managing the interlocking in an integrated manner. Interlocking and switch control logic is optimized using position reports of communicating trains. The integrated design includes:
