Road section type signal lamp and coordination control method

The invention relates to the technical field of traffic signal lamps, and discloses a road section type signal lamp and a coordination control method, and the method comprises the steps: carrying out the sequential numbering of signal lamps at different intersections of the same road section, and presetting the display modes of all signal lamps under different traffic conditions; the traffic flow monitoring module monitors the traffic flow data of the intersection where the signal lamp is located in real time; the congestion degree of the current intersection is judged according to the obtained vehicle number, and the required time for driving to the next intersection is calculated according to the obtained vehicle speed information; the signal lamp circulation duration of the downstream intersection of the same road section is adjusted in sequence; and the light brightness of the signal lamp is adjusted according to the illumination intensity, and starting of the cooling fan is controlled according to the te
