ALTERNATIVE DUAL MODE NETWORK CONTROL STRATEGIES

From a literature survey a qualitative evaluation was made of four network control strategies for the fundamental control philosophy of the moving synchronous slot. In the literature concerning automated transportation systems, such as dual mode, a great deal of effort has been expended in discussing the pros and sometimes the cons of a specific control concept without reviewing other control strategies that may be available. The paper summarizes the major advantages and disadvantages associated with four control strategies for the moving synchronous slot. A description of each of these control strategies is provided and conclusions are made showing that the deterministic slot/cycle concept and the quasi-synchronous slot concept with entrance station throughput modulated by historic demand data are the most promising. Additional investigations of these two concepts showed that a further study of alternative network control strategies is needed, oriented towards addressing the issues of network capacity, interchange design, passenger convenience and system failure and recovery.
