Computer program, vehicle speed estimation device and estimation method, and congestion tendency estimation device and estimation method

摘要

A computer program according to one embodiment of the present invention is a computer program for causing a computer to function as an apparatus for estimating a vehicle speed, the computer program comprising: a plurality of target points whose statistical speed gradually decreases from a high speed threshold to a low speed threshold. An extraction process of extracting a speed transition section including: a calculation process of calculating a propagation speed of a traffic jam based on a first speed sequence having statistical speeds of a plurality of target points included in the speed transition section as elements. And estimating a vehicle speed in a predetermined section including the speed transition section based on the propagation speed.
