Lane change and overtaking are frequent driving maneuvers in daily drive which are related to traffic safety and efficiency. Most prevailing studies focus on lane-changing and overtaking modeling, while few studies investigate the effect of traffic conditions and the individual differences in lane change and overtaking maneuvers. To fill the gap, this paper conducts a driving simulator experiment to test the effect of traffic density on drivers’ lane change and overtaking maneuvers on urban road. Lane change frequency, duration, average speed and acceleration were extracted as key variables of lane change maneuvers, while overtaking frequency, duration, initial spacing and headway, instantaneous speed and acceleration were analyzed as the major overtaking variables. The differences between left and right overtaking maneuvers were also investigated in this study. The results showed that the demand for lane change and overtaking increases with traffic density and drivers tend to conduct risky overtaking in high traffic density situation. In addition, it was found that drivers did not show a tendency on the direction of overtaking, but right overtaking involves more risk than left overtaking because of the restricted field of view, the higher initial speed and smaller spacing before overtaking.
