摘要
A computer program according to an aspect of the present disclosure is a computer program for causing a computer to function as a vehicle speed estimating device. The program causes the computer to function as a data processing unit executing: an extraction process of extracting a speed transition section which includes a plurality of target points and in which a statistical speed gradually decreases from a speed not lower than a high-speed threshold to a speed not higher than a low-speed threshold; a calculation process of calculating a propagation speed of traffic congestion on the basis of a first speed sequence having, as elements, statistical speeds at the plurality of target points included in the speed transition section; and an estimation process of estimating a vehicle speed in a predetermined section including the speed transition section, on the basis of the propagation speed.
