Traffic impedance is an important parameter in the urban traffic network's study. It directly affects traffic flow path selection and flow assignment. Traffic impedance can be described by a traffic impedance function in the traffic flow assignment, so the accuracy of establishing a traffic impedance function immediately affects the study's performance on the traffic network equilibrium. In this paper, a traffic impedance function is established, which is based on a narrow-sense traffic impedance and grey system theory. In order to effectively determine this, the section between Lujia Village and Lijia Village in Xi'an is analyzed and the traffic impedance function of this section is fitted. Through a comparison with the survey data, it is shown that the analogue result is accurate. Because this section is located in the urban arterial street, the fitted traffic impedance function has a valuable reference to similar situations, especially the urban arterial street in Xi'an.
