  • Patent number: 11798408
    Abstract: Provided are a green wave speed determination method, an electronic device and a storage medium, which relates to the field of artificial intelligence, particularly, the field of intelligent traffic technology. The implementation scheme is as follows: a stop position of a vehicle to be detected at an intersection and waiting time of an indicator light at the intersection are acquired; and a green wave speed of the vehicle to be detected is determined according to a traffic condition type, the stop position and the waiting time.
    Type: Grant

  • Publication number: 20230094992
    Abstract: A method for generating a wireless signal fingerprint database includes: obtaining an initial atmospheric pressure value, in which the initial atmospheric pressure value is an atmospheric pressure value collected when a terminal enters indoors; obtaining periodically a current wireless signal fingerprint and a current atmospheric pressure value collected by the terminal; and determining a floor corresponding to the current wireless signal fingerprint based on the initial atmospheric pressure value and the current atmospheric pressure value, to obtain the wireless signal fingerprint database.
