The invention relates to a multi-intersection variable guide lane and traffic signal cooperative control optimization method, which comprises the following steps of: acquiring traffic flow data of each turn of each entrance lane of each intersection in an analysis time period, and judging whether setting and opening conditions of a variable guide lane are met or not; according to the intersection correlation degree model, calculating the correlation degree between the intersections, and determining a coordination area of multiple intersections; a multi-intersection variable guide lane and traffic signal cooperative control double-layer optimization model is adopted, the minimum regional vehicle average delay is taken as an optimization target, and a multi-intersection variable guide lane function division scheme and a signal timing scheme are optimized; comparing whether optimization target requirements are met or not after optimization; and judging whether the result of the model causes overflow. According to the method, a multi-intersection variable guide lane and traffic signal cooperative control double-layer optimization mathematical model is constructed, dynamic optimization of regional road network road space resources and time resources is realized, and the utilization rate of the whole regional road network space-time resources is improved.
