PROBLEM TO BE SOLVED: To provide a travel time calculation device and travel time calculation method capable of highly accurately calculating a travel time of a prescribed section of a road.SOLUTION: The travel time calculation device includes: a sectional number-of-vehicle calculation unit that calculates the sectional number of vehicles present at a prescribed section of a road at any time point; an outgoing detection unit for detecting the number of vehicles going out from the section; and a travel time calculation unit that calculates a time difference between a time when the number of detected vehicles becomes equal to the sectional number of vehicles, and the any time, as a travel time of the section. The number of vehicles going out from the section can be detected, for example, by acquiring detection data detected by a vehicle detector provided at an outgoing point of the section (a downstream point).
【課題】道路の所定の区間の旅行時間を精度よく算出することができる旅行時間算出装置及び旅行時間算出方法を提供する。【解決手段】旅行時間算出装置は、任意の時点で道路の所定の区間に存在する車両の区間台数を算出する区間台数算出部と、区間から流出する車両の台数を検出する流出検出部と、検出した台数が区間台数に等しくなる時点及び任意の時点の間の時間差を区間の旅行時間として算出する旅行時間算出部とを備える。区間から流出する車両の台数は、例えば、区間の流出地点(下流地点)に設けられた車両感知器で感知した感知データを取得することにより検出することができる。【選択図】図1
