Abstract:

For a better solution of the incoordination of regional control strategies in traditional traffic control system, this paper proposes a traffic coordination control strategy of regional boundary on the basis of traffic state identification and develops a traffic coordination control model based on fuzzy control and hierarchical coordination. The actual effect of this model is tested with the micro simulation tool VISSIM, and the result shows that the model could efficiently coordinates the regional boundary with its upper, lower intersection so that could assure the rapid evacuation of traffic congestion and increase the operation benefit of the whole system.

Key words: engineering of communication and transportation system, traffic coordination control, regional boundary, fuzzy control, hierarchical coordination
