The invention relates to an intelligent traffic signal control method and system based on multi-modal data fusion, and the method comprises the steps: carrying out the advanced data analysis clustering of multi-modal traffic data collected by a multi-source sensing device, and obtaining the dynamic correlation degree of traffic flow; performing adaptive threshold setting according to the traffic flow dynamic correlation degree to obtain dynamic division sub-regions; performing state space construction on the dynamically divided sub-regions, and performing multi-objective optimization dynamic adjustment to obtain an initial signal control scheme; carrying out distributed calculation on the initial signal control scheme, and carrying out red wave band cooperative control to obtain an adjustment signal phase strategy; and performing digital twin drive real-time verification on the signal phase adjustment strategy, and performing simulation feedback processing to obtain a multi-target signal control scheme. The method can effectively solve the problem of lack of comprehensiveness of control decisions caused by single data source of a traditional method.
