PROBLEM TO BE SOLVED: To provide a traffic information provision device, a computer program and a traffic information provision method capable of providing updated traffic information without temporal delay.SOLUTION: A traffic information provision device comprises: an acquisition section which acquires probe information about a vehicle traveling a road section at a downstream side of the section; a transit time identification section which identifies, on the basis of the acquired probe information, upstream transit time from when the vehicle passes an upstream point of the road section until when the vehicle reaches a predetermined point at the downstream side thereof and downstream transit time from when the vehicle passes a downstream point of the road section until when the vehicle reaches a predetermined point; a cumulative traffic volume calculation section which calculates, on the basis of detection data obtained through respective vehicle sensors, an upstream cumulative traffic volume at the upstream point during the upstream transit time and a downstream cumulative traffic volume at the downstream point during the downstream transit time; and a sectional vehicle count calculation section which calculates the number of vehicles existing in the road section on the basis of the calculated upstream cumulative traffic volume and the downstream cumulative traffic volume.SELECTED DRAWING: Figure 2
【課題】時間遅れのない最新の交通情報を提供することができる交通情報提供装置、コンピュータプログラム及び交通情報提供方法を提供する。【解決手段】交通情報提供装置は、区間を走行した車両のプローブ情報を区間より下流側で取得する取得部と、取得したプローブ情報に基づいて、車両が区間の上流地点を通過した時点から区間より下流側の所定地点に到達するまでの上流通過時間及び区間の下流地点を通過した時点から所定地点に到達するまでの下流通過時間を特定する通過時間特定部と、各車両感知器で得られた感知データに基づいて、上流通過時間の間の上流地点での上流累積交通量及び下流通過時間の間の下流地点での下流累積交通量を算出する累積交通量算出部と、算出した上流累積交通量及び下流累積交通量に基づいて区間内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を備える。【選択図】図2
