1. A system comprising a server computer and a first on-vehicle device of a first vehicle which communicates with the server computer via a communication line, wherein
the first on-vehicle device includes a microcomputer programmed to:
collect sensor information detected by a sensor provided to the first vehicle,
transmit the sensor information to the server computer via the communication line,
receive first data including a line speed of the communication line in an expected traveling area of the first vehicle, from outside of the first vehicle,
determine, as a predicted line speed, the line speed of the communication line at an expected traveling position of the first vehicle in a future, on the basis of the first data that is received, and
determine a parameter relevant to transmission of the sensor information to the server computer, on the basis of the predicted line speed.
