Abstract

Based on the push and pull approach, a kind of adaptive disseminating mechanism is presented, which combines push with pull, by which the system of emergency coordination center in urban rail transit line network can dynamically allocate the available resource between push and pull clients so as to optimize the sending time delay of data chunk in network given their desired currency. The major conclusion is the approach of combined push with pull can fit to stringent coherency requirements information and less stringent coherency requirements information. Also it can fit to information provided according to user’s requirements. The approach can better meet the requirement of currency of information on urban rail transit line network.
