To provide a congestion prediction method and congestion prediction device capable of correctly predicting a congestion and contributing to convenience of a person who uses congestion prediction data using inter-vehicle distance information.SOLUTION: A congestion prediction device includes: imaging devices 21, 23 arranged in an own vehicle so as to image a front vehicle and a following rear vehicle which are traveling on a travel lane adjacent to an own vehicle travel lane; a processing device 32 for obtaining a distance between front and rear vehicles based on data from the imaging devices; and a server 28 for collecting an inter-vehicle distance output from the processing device and measurement position information and predicting a congestion based on the inter-vehicle distance information for each measurement position. When a congestion is predicted, a front side and a rear side are imaged by the imaging means mounted on an own vehicle, so as to use an inter-vehicle distance between a front vehicle and a following rear vehicle which are traveling on a travel lane adjacent to an own vehicle travel lane.SELECTED DRAWING: Figure 2
【課題】より正確に渋滞予測することができて、車間距離情報を用いた渋滞予測データを利用する者の利便に供することが出来る渋滞予測方法および渋滞予測装置を提供する。【解決手段】渋滞予測装置は、自車両に設置され自車走行レーンに隣接する走行レーンを走行中の前方車両と後続する後方車両とを撮り込む撮影装置21、23と、撮影装置からのデータに基づき前後車両間距離を求める処理装置32と、処理装置から出力された車間距離と計測位置情報を収集し、計測位置ごとに車間距離情報とに基づいた渋滞を予測するサーバ28と、を備えている。渋滞予測に際して、自車両に搭載した撮影手段により前方と後方を撮影し、自車走行レーンに隣接する走行レーンを走行中の前方車両とこれに後続する後方車両との間の車間距離を利用する。【選択図】図2
