According to the basis of clash-points formed with traffic flows on every urban junctions,the principle of phase optimization is provided and the optimal calculation by network figure is solved,which presents multi-phase orgnization for junctions in cities to oppose flows c.

Studying the traffic of the crossroad, the design adopts two fuzzy controllers: phase optimization controller optimizing the phases according to the traffic and green light delay controller alloc.

General signal offset optimization strategies are introduced,taking traffic signal control integrated with urban traffic guidance system into account,different waiting statuses of platoon at stop line are studied,the relationship between route travel time and offset is set up,the offset optimization technique considering real time coordination be.
