The invention provides an intersection signal control and variable lane robust collaborative optimization method, and belongs to the technical field of urban traffic management. The method is specifically implemented as follows: firstly, optimizing time period selection and time interval division are carried out, and a signal control scheme is implemented for each time interval on the basis that channelization of a variable lane in the same time period is not changed; secondly, historical data extraction and real-time data acquisition are carried out, and the traffic volume is counted according to the time interval; thirdly, proposing a robust optimization model and algorithm driven by historical data; taking the generalized saturation as an optimization index, and solving by using a double-layer nested genetic algorithm; secondly, proposing a robust optimization model and algorithm jointly driven by historical data and real-time data; taking the vehicle average delay as an optimization index, and solving by using a multi-mode genetic algorithm; and finally, determining the selection of the joint mode of the two types of data in the next time period, namely, calculating the standard deviation value of the traffic historical data in the previous five days as a sample, and determining the standard deviation value according to the interval.
