A first apparatus obtains first information, where the first information includes information about a road and/or information about an object on the road, and the object on the road includes a vehicle and/or a pedestrian on the road. The first apparatus determines a driving behavior of the first apparatus based on the first information and a capability of the first apparatus. Even if the capability of the first apparatus cannot be used to process complete information of the first information, the first apparatus can still determine the driving behavior of the first apparatus based on a part of information in the first information. This resolves a problem that a capability of an apparatus cannot fully match road side information. According to the technical solution, apparatuses with different capabilities can cooperate with different roads with different capabilities, to improve travel efficiency and safety.

The present disclosure provides a terahertz biological detection method and a device comprising the same, in which biological samples with different molecular formulas have their characteristic peaks in the terahertz band. In the process of sweeping frequency with terahertz, when the terahertz frequency point corresponds to the characteristic peak frequency of the substance to be detected, resonant absorption occurs, and the transmitted/reflected terahertz wave electric field intensity will suddenly decrease. In the electromagnetically induced transparency spectrum corresponding to the Rydberg quantum state, the signal splitting amplitude is significantly reduced. Therefore, the characteristic peak frequency and specific content of the substance to be detected can be accurately determined by comparing the dependence of the Rydberg quantum state with the additional terahertz electric field intensity on the excitation energy level.
