Abstract: With growth of urban road traffic volume and the increase of road network density,correlation between adjacent road intersections is becoming more and more obvious．An intersection traffic signal adjustment tends to affect the health of a number of adjacent intersections road traffic flow．Its congestion may over time gradually spread to within a few blocks and regions all around the intersection．Therefore increasingly high demands of urban traffic signal control to reach a variety of advanced control technology integration,achieve the purpose to adjust a control parameter,in order to achieve dynamic coordination within the city-wide traffic control,to satisfy traffic demands,and then let the road traffic and the transport demand to reach a new balance．This article introduced the use of the green wave effect collaborative strategies adjacent green extension of fuzzy control in order to solve the problem of coupling between intersections road．This algorithm makes Signal Timing to be more flexible.
