To provide a novel and improved determination device, determination method, and determination program capable of enhancing performance to determine whether a congestion is the accidental congestion.SOLUTION: A determination device includes: a calculation section for calculating a first time at which a speed of a traffic flow is increased to be a first border speed in a first zone being the zone in the downstream of a front zone of a congestion, and a second time at which the speed of a traffic flow is increased to be the first border speed in a second zone being the zone in the downstream of the first zone; and a determination section for determining whether the congestion is the accidental congestion based on anterior-posterior relation between the first time and the second time calculated by the calculation section.SELECTED DRAWING: Figure 2

    【課題】渋滞が突発渋滞であるか否かの判定性能を向上することが可能な、新規かつ改良された判定装置、判定方法および判定プログラムを提供する。【解決手段】渋滞の先頭区間より下流の区間である第1の区間において、交通流の速度が増加して第1の境界速度になった第1の時刻と、前記第1の区間より更に下流の区間である第2の区間において、前記交通流の速度が増加して前記第1の境界速度になった第2の時刻とを算出する算出部と、前記算出部によって算出された前記第1の時刻と前記第2の時刻との前後関係に基づいて、前記渋滞が突発渋滞であるか否かを判定する判定部と、を備える判定装置。【選択図】図2
