The invention relates to a driver call making identification method in an intelligent transportation system. In cooperation with an intelligent traffic violation detection system, the method determines whether a driver makes a call while driving by acquiring an image by using traffic intersection or traffic crossroad video monitoring, separating a driver position from the image, positioning a face to obtain a face image; creating a skin color segmentation model like Mahalanobis distance by using face pixels as sample points, performing skin color segmentation on the driver image, extracting a hand image, computing the center of mass and the inclination angle of the hand image, setting an illegal region according to the length and the width of a face, and determining a relation between the inclination angle range and the center of mass of the hand image and the illegal region.
