The invention provides a single-intersection self-adaptive signal timing optimization method and device based on a multi-scale network, and relates to the technical field of signal lamp control, and the method comprises the steps: obtaining a signal lamp monitoring state, matching each phase control lane of a signal lamp with each lane monitored by a road state monitoring device, and obtaining a signal lamp control state; whether self-adaptive timing optimization is carried out or not is judged based on the lane monitoring data and the signal lamp monitoring state; after the self-adaptive timing optimization is determined to be carried out, carrying out multi-scale division on the lane monitoring data, and respectively carrying out intersection flow prediction according to each scale; signal timing is carried out according to the predicted flow, a signal timing result is issued to a signal control machine for operation, and the road state is monitored in real time. The traffic modes and influence factors under different time scales can be captured through the multi-scale network, the complexity and variability of traffic data are effectively dealt with, and the prediction accuracy and robustness are improved.
