Abstract

The invention discloses a multi-signal lamp linkage control method and system for intelligent urban traffic, and relates to the technical field of intelligent traffic, and the method comprises the steps: constructing an urban multi-level response system which covers the response architecture of three levels of intersections, regions and cities; a sensing acquisition network is accessed to collect weather information and traffic information, and traffic abnormal conditions in the response range of each level are identified; integrating the meteorological data, the traffic data and the traffic abnormal information into an urban multi-level response system according to the association of the response levels, and analyzing the traffic signal lamp strategy of each level so as to formulate the traffic control strategy of each level; and performing overall optimization on the traffic control strategy of each level in combination with the correlation characteristics of each level region, and finally forming a global collaborative control strategy. Therefore, the technical effects of fine control and global optimization, and enhancement of the adaptability and the overall operation benefit of the traffic system are achieved.
