The invention provides a microscopic traffic simulation model parameter calibration method. The microscopic traffic simulation model parameter calibration method comprises the steps that simulation model parameters are preprocessed; establishing an evaluation index system of a road plane intersection microscopic traffic simulation model parameter set operation result; initializing and evaluating parameters of the simulation model; performing simulation model parameter sensitivity analysis; scheme feasibility testing; calibrating parameters of the simulation model; and verifying the simulation model. Compared with the prior art, the traffic flow operation characteristics in different road traffic scenes can be accurately restored through efficient and convenient systematic calibration.
