The invention belongs to an unmanned vehicle test and verification platform and a test method thereof in the field of unmanned vehicles. The platform comprises a driving simulation system, an experimental field, a network system, an upper level management center and an unmanned vehicle. The driving simulation system constructs a driving environment of a virtual vehicle according to the information collected in a natural scene; the traffic scene of the actual site of the experimental field coincides with the scene modeled by the driving simulation system; and the upper level management center is used for establishing a simulator driving environment, controlling the driving simulation system and processing data; the unmanned vehicle is a test vehicle and is automatically driven in the experimental field; and the driving information of the unmanned vehicle is transmitted to the upper level management center through a network system and then transmitted to the driving simulator of the driving simulation system. According to the invention, function verification and performance evaluation of the unmanned vehicle can be studied, and meanwhile, influences by the unmanned vehicle on an actual traffic flow can be studied and evaluated through the platform.
