Abstract: Disclosed are a method and system for distributed redundancy control on an intelligent traffic network, the method includes: sending, by each communication control node, messages for electing a primary device to the other communication control nodes, and electing a primary device from the plurality of communication control nodes according to preset priorities of the communication control nodes, and backing up data of the communication control node in the primary device; and sending state detection messages to the other communication control nodes, if a response message of the communication control node to the state detection message indicates that the communication control node cannot control any action of a device served by the communication control node, controlling action of the device served by the communication control node, and adjusting control intervals of time of signaling lamps at junctions corresponding to the communication control nodes in a redundant network according to traffic flows.
