The invention discloses a dynamic optimization method for an intersection short variable lane system. The method comprises the steps of obtaining an intersection, and judging whether an intersection entrance lane is an entrance lane of a conditionally set variable lane or not; acquiring system data, and preprocessing the system data; judging whether the variable lane implements a space-time integration strategy or not based on the strategy condition; if the strategy condition is met, implementing a space-time integration strategy, and performing space-time integration optimization based on system data; and analyzing the time-space integrated optimization result based on the theoretical vehicle passing through each period and the queuing length. Based on traffic real-time data such as vehicle flow, queuing length and the like and big data calculation capability, a specific time-space integrated optimization algorithm is combined on a road network topological structure, urban road traffic conditions are identified and analyzed, an optimization scheme is proposed, and the method can achieve the real-time traffic optimization based on data with high update rate such as Internet data and the like. And changing traffic demands can be rapidly adapted.
