Development of track utilization decision support system (TUDSS) is one of the most important component parts for realizing decentralized and self-regulated control in railway passenger stations. The system can provide technical and decision supports for dispatchers to solving track utilization problems (TUP), and its development thus needs many key technologies. Furthermore, we analyze and further put forward real-time dynamic adjustment technology, object-based graphical block technology, cross time span consistency processing technology, carrying capacity of station throat calculating principle and also other key technologies to help to develop the system and realize its functions. Moreover, its trial test results show that the system can make and adjust track utilization plans effectively and fast, and meet the diversified practical needs for TUP in passenger stations.
