摘要:
The present disclosure relates to a method for controlling a first device (101A). The method comprises: collecting a first set of data using a first type of sensors of the first device (101A). A second set of data of a second type of sensors may be received from at least another second device (101B-107) over a communication channel. The first and second sets of data may be combined for determining a current vehicle traffic configuration. The first device (101A) may be controlled in accordance with the current vehicle traffic configuration.
