摘要： A system for collecting traffic information that includes at least one first mobile node; at least one second mobile node; at least one data collection node; and a central processing station. At least one packet is transmitted between the first mobile node and the second node. The data collection node includes a packet search analyzer to determine an identifier that identifiers the first mobile node or the second mobile node from the at least one packet. The central processing station is linked to the data collection node and communicates traffic information associated with the identifier.
