The invention discloses a self-learning type intersection all-time signal control scheme optimization method. The method comprises the steps of obtaining traffic demand data and intersection channelization information of a signal control scheme in all time periods in the whole day; determining a mapping relation between the intersection flow and the time period information and the signal period duration according to historical data, and determining the signal period duration in combination with the intersection flow in the corresponding time period; calculating phase saturation based on the traffic demand data, the intersection channelization information and the signal lamp phase information; and based on the phase saturation and the signal period duration, an integer programming model is established to calculate the green light time of each phase, and a signal control scheme in a corresponding time period is obtained. The signal period duration and the green light time of each phase are optimized based on the fuzzy reasoning theory, the integer programming model and the like according to the intersection channelization information and the traffic demand data, a proper signal control scheme is generated, traffic conflicts are remarkably reduced, and the road traffic efficiency is improved.
