Construction method of urban traffic signal self-organization rule based on fluid dynamics

The invention relates to a method for structuring city traffic signal automatically organize rule based on fluid dynamics in the field of traffic project technology. The invention uses city traffic signal control system as traffic network processing, each intercross as intelligent body with auto collecting and processing function; each intercross possesses two suits of cell salve robot to achieve the dynamic resolution of each intercross traffic signal control; it uses the resemblance between traffic flow and fluid flow to introduce fluid dynamics to establish the balance model of traffic flow and sets city traffic signal automatically organize and control rule based on four phases switching at the same time; it sets traffic intercross phase quoting rule to achieve the real time resolution of traffic system signal model.
