This paper reports an experimental study on oscillation growth in mixed traffic flow of automated vehicles (AVs) and human vehicles (HVs). The leading vehicle moves with constant speed in the experiment. The following vehicles consist of six programmable AVs and different number of HVs. Thus, the market penetration rate (MPR) of AVs decreases with the increase of platoon size. The constant time gap car-following policy is adopted for the AVs and the gap is set to 1.5 s. The experiment shows that in the 7-vehicle-platoon, the oscillations grow only slightly. In the 10-vehicle-platoon, the AVs could still significantly suppress the growth of oscillations. With the further decrease of MPR of AVs in the 13- and 20-vehicle-platoon, the AVs become having no significant impact on oscillation growth. On the other hand, the flow rate of mixed platoons is lower than that of All-HV platoons of the same size. A simulation study is carried out, which exhibits good agreement with the experiment.
