Cluster member arrival time estimating method

The invention relates to a cluster member arrival time estimating method. In the method, a cluster is established aiming at a specific event mainly through a Web server; all cluster members in the cluster share GPS (global positioning system) information by utilizing related mobile equipment, so that the Web server can conveniently estimate the estimated arrival time for each cluster member to arrive at an event initiating place, thus being favorable for all the cluster members or event organizers to learn the current position and estimated arrival time of each member in time and providing convenience for the initiation and organization of the event.
