To provide a traffic situation determination device that enables a difference in congestion situation produced between traveling directions of vehicles traveling on road links to be determined early.SOLUTION: The traffic situation determination device includes: a probe information acquisition unit that acquires probe information on vehicles; a speed calculation unit that for each of one or more sub-sections obtained by dividing a predetermined target section at an interval having a distance shorter than a road link which is a unit interval on a road to be used for calculation of a travel time, calculates a travelling speed of the vehicles in the sub-sections based on the probe information; a speed property determination unit that determines a speed property of the vehicles in the target section based on the travelling speed; and a difference determination unit that based on the speed property, determines whether a difference in congestion situation is produced between traveling directions of the vehicles traveling in the target section.SELECTED DRAWING: Figure 8

    【課題】道路リンクを走行する車両の進行方向間で発生する渋滞状況の差異を早期に判定することのできる交通状況判定装置を提供する。【解決手段】交通状況判定装置は、車両のプローブ情報を取得するプローブ情報取得部と、前記プローブ情報に基づいて、旅行時間の算出に用いられる道路上の単位区間である道路リンクよりも短い距離の間隔で所定の対象区間を分割することにより得られる1以上のサブ区間の各々について、前記車両の当該サブ区間における走行速度を算出する速度算出部と、前記走行速度に基づいて、前記対象区間における前記車両の速度特性を決定する速度特性決定部と、前記速度特性に基づいて、前記対象区間を走行する前記車両の進行方向の間で渋滞状況に差異が生じているか否かを判定する差異判定部とを備える。【選択図】図8
