The invention discloses a signal green wave coordination route optimization control method based on a real-time road condition. The method comprises the following steps: S1, acquiring road network information, real-time road condition traffic data and annunciator control scheme data; S2, constructing a green wave coordination effectiveness comprehensive analysis model based on the fuzzy theory, and calculating the effectiveness of road section green wave coordination; S3, clustering the road sections with high green wave coordination effectiveness based on an improved hierarchical clustering algorithm, and automatically generating a coordination route; and S4, optimizing the overall coordination scheme of the coordination route based on the real-time road section speed data of the Internet, and issuing a coordination command. The problem that a traditional signal system coordination scheme can only be executed based on a static solidification scheme and is difficult to adapt to the real-time road conditions is solved. A method for evaluating the road green wave coordination effectiveness is provided, and theoretical support is provided for traffic signal control; and the problem that the traditional signal system coordination scheme route cannot be dynamically changed along with the road conditions is solved.
