PROBLEM TO BE SOLVED: To provide a travel environment evaluation system capable of evaluating the travel environment of a vehicle well on the basis of an actual situation.SOLUTION: An evaluation system includes: an image obtainment part 110 for obtaining image data of outside of a vehicle; a travel easiness determination part 220 for analyzing the image data obtained via the image obtainment part 110, identifying a factor of a travel uneasiness contained in the image data, thus evaluating a travel environment representing a travel easiness of the vehicle on the basis of the identified factor quantitatively for each of given spots; and a confidence degree calculation part 230 for calculating a confidence degree as a value that decreases proportionately as a factor of travel uneasiness, the factor constituting a source of evaluation of the travel environment, tends to change with a passage of time. Further, the travel easiness determination part 220 re-evaluates the travel environment with the degree of confidence calculated by the confidence degree calculation part 230 considered.SELECTED DRAWING: Figure 2

    【課題】車両の走行環境の評価として、より実態に即した評価を行うことのできる走行環境評価システムを提供する。【解決手段】このシステムは、車両外部の画像データを取得する画像取得部110と、画像取得部110を通じて取得された画像データを解析することより当該画像データに含まれる走りにくさの要因を特定して当該特定した要因に基づく車両の走りやすさを示す走行環境を所定の地点ごとに定量的に評価する走りやすさ判定部220と、走行環境の評価元となる走りにくさの要因が時間の経過に伴って変化しやすいものほど低い値として信頼度を算出する信頼度算出部230とを備える。そして、走りやすさ判定部220は、信頼度算出部230により算出される信頼度を加味して走行環境を再評価する。【選択図】図2
