The invention provides an intersection variable lane optimization selection method, an electronic device and a storage medium. The intersection variable lane optimization selection method comprises the following steps: acquiring road parameters of all entrance lanes A1 of a to-be-optimized road section; screening out an entrance lane A2 with a conditionally set variable lane from the A1 accordingto a first optimization rule; acquiring a traffic condition of the A2 in a preset period, and calculating traffic flow parameters according to each operation rule; screening out an entrance lane A3 which is possibly suitable for setting the variable lane from the A2 according to a second optimization rule; calculating an all-day steering flow ratio unequal coefficient of the A3 in the preset period; determining an optimal scheme of the A3 in a preset period according to a third optimization rule; calculating an improvement proportion of the optimal scheme of the A3; and according to a fourth optimization rule, based on the improvement proportion of the optimal scheme, screening out an entrance lane A4 suitable for setting the variable lane from the A3, and outputting the optimal scheme corresponding to the A4 and the improvement proportion for preview.
