The application discloses a method and a system for detecting traffic vehicles. The method comprises the steps of: determining an object time length and an object maximum value signal when difference values between all object earth magnetic field real-time signals detected within a period of time and a background earth magnetic field value determined in advance are all greater than a first threshold value; determining an object deviation factor according to the object maximum value signal and the background earth magnetic field value; performing judgement for an adjacent lane interference condition when the object deviation factor is greater than a second threshold value, and performing judgement for a vehicle passing condition if the adjacent lane interference condition is not satisfied. The method of the present invention judges whether the object deviation factor and the object time length satisfy the adjacent lane interference condition on the premise that the object deviation factor is greater than the second threshold value, thereby reducing vehicle statistical bias caused by interference generated by extraneous non-vehicle factors or interference on an object lane due to vehicles on adjacent lanes, and improving accuracy of a statistic result.
