The invention relates to a racing yard-based vehicle test system, a driving behavior judgment control method and an accident early warning method, the vehicle test system comprises a central terminaldevice and a road terminal device, and the road terminal device is arranged in a racing yard, and comprises an auxiliary positioning facility, a communication facility, a traffic sign marking, a traffic control and guidance facility, a road end calculation facility and a traffic perception facility. The test system achieves an open environment road test and a track closed area mixed traffic flow test of an automatic driving vehicle based on a racing yard. The judgment control method comprises the following steps: constructing and training an aggressive driving scene understanding model based on data obtained by a vehicle aggressive driving test in a high-speed driving environment of a vehicle test system; and acquiring driving behavior data and driving scene information of the automatic driving vehicle in real time, and achieving judgment control of the aggressive driving behavior of the automatic driving vehicle based on the aggressive driving scene understanding model. Compared withthe prior art, the test system has the advantages of diversified test functions, simplicity in implementation and the like.
