In order to improve extra-width

ultra-height of highway vehicle management work efficiency

width and height detection system of intelligent vehicle is more and more widely applied.Because of misjudge of detecting system on the widest value of vehicle rearview mirror

leading to artificial frequent repetition and overrun station traffic is slow.Aiming at above defects propose method using fitting ability of generalized regression neural network to estimate the reason of the maximum width value generating.Experiments show that the method can effectively remove the widest value caused by rear view mirror in process of testing

improve the accuracy and efficiency of traffic.
