| Zusammenfassung: | The invention discloses a bidirectional green wave maximum bandwidth coordination control method suitable for a traffic flow speed distribution interval. The method comprises the following steps: S1, acquiring static traffic data of a trunk road and signal timing parameters of an intersection; s2, acquiring historical and real-time traffic flow speed data, and calculating a curve fitting function of vehicle speed distribution; s3, establishing a maximum bandwidth coordination control model based on the recommended vehicle speed; s4, establishing an expected bandwidth coordination control model based on the vehicle speed distribution interval; s5, establishing a bidirectional green wave maximum bandwidth coordination control model suitable for a traffic flow speed distribution interval; and S6, solving the bidirectional green wave maximum bandwidth coordination control model, and outputting a bidirectional green wave bandwidth maximized coordination control timing scheme. According to the method, a larger expe |
