Abstract:
1. A traffic state predicting apparatus comprising: a processor configured to acquire traffic information on a predicted travel time for each of one or more links constituting a road on a map, sections in the link each having a determined level of congestion, a congestion reference position being a reference position for the section for which the level of congestion is determined, and a total section length of the sections for each of which the level of congestion is determined to be congested; and a processor configured to create parameters on each of the links based on which the sections in each of the links are obtained for which the level of congestion is determined, wherein the parameters include a smooth traffic speed indicating a threshold value of a traffic speed for which a level of congestion is determined to be smooth, a congested traffic speed indicating a threshold value of a traffic speed for which the level of congestion is determined to be congested, and congestion reference positions each of which is a reference position for a congested section, wherein the processor configured to create comprises:
