The invention discloses an intersection timing parameter optimization model construction method and an intersection signal optimization method. The intersection timing parameter optimization model construction method comprises the steps of obtaining a plurality of training samples in a target timing duration, wherein the training samples comprise a timing scheme in a target interval duration, timing effect evaluation data corresponding to the timing scheme, corresponding intersection environment data and timing parameters; and based on the plurality of training samples, carrying out iterativetraining on a neural network model until a loss value of a loss function corresponding to the neural network model satisfies a target condition, and obtaining an intersection timing parameter optimization model. Through the constructed intersection timing parameter optimization model, the timing parameters of the intersection can be optimized quickly and accurately, and the intersection is timed according to the optimized timing parameters, so that the traffic capacity of an intersection is improved.
