To improve the accuracy of calculating the delay time per vehicle due to waiting at a traffic light.SOLUTION: A device according to an aspect of the present disclosure includes: an acquisition unit for acquiring probe information of a probe vehicle passing on an incoming route to an intersection; and an information processing unit that uses the probe information as source data to perform a calculation process of a delay time per vehicle due to waiting for a signal on the incoming route. The calculation process includes: a first process for calculating, based on the probe information, a plurality of section speeds, which are average speeds of vehicles for each section of the incoming route divided into a plurality of sections; a second process for calculating, based on the plurality of section speeds, the total number of sections, which is the total number of sections included in the signal waiting sections on the incoming route; a third process for calculating the average travel time of the signal waiting sections based on the total number of sections; and a fourth process for calculating the delay time based on the total number of sections and the average travel time of the signal waiting sections.SELECTED DRAWING: Figure 10

    【課題】 信号待ちによる車両1台当たりの遅れ時間の算出精度を向上する。【解決手段】 本開示の一態様に係る装置は、交差点への流入路を通行するプローブ車両のプローブ情報を取得する取得部と、前記プローブ情報を元データとして、前記流入路における信号待ちによる車両1台当たりの遅れ時間の算出処理を実行する情報処理部と、を備える。前記算出処理には、前記プローブ情報に基づいて、前記流入路を分割してなる複数の区間ごとの車両の平均速度である複数の区間速度を算出する第1処理と、前記複数の区間速度に基づいて、前記流入路における信号待ち区間に含まれる前記区間の総数である区間総数を算出する第2処理と、前記区間総数に基づいて、前記信号待ち区間の平均旅行時間を算出する第3処理と、前記区間総数と前記信号待ち区間の平均旅行時間に基づいて、前記遅れ時間を算出する第4処理と、が含まれる。【選択図】 図10
