PROBLEM TO BE SOLVED: To provide a vehicle travel support system which supports smooth merging of vehicles in accordance with a traffic condition at a junction on a highway.SOLUTION: A vehicle travel support system comprises: a main line vehicle detection section (101) which measures a position and a velocity of a main line traveling vehicle traveling in a direction toward a merging zone on a first lane, connected to a merging lane, among lanes of a main line; a merging vehicle detection section (201) which is installed at a roadside of the merging lane and measures the position and the velocity of a merging lane traveling vehicle traveling in a direction toward the merging zone on the merging lane; and first travel support processing sections (103, 203 and 207) which predict arrival times when the main line traveling vehicle and the merging lane traveling vehicle arrive at the merging zone on the basis of respective measurement results and, when an absolute value of a difference between the predicted arrival times of respective vehicles cannot be kept to not less than a first allowable value, output a travel lane change instruction to instruct the main line traveling vehicle to go over from the first lane to a neighboring lane which is not connected to the merging lane.SELECTED DRAWING: Figure 1
【課題】幹線道路の合流部の交通状況に応じて、スムーズな合流を支援する車両走行支援システムを得る。【解決手段】本線の車線のうち、合流車線と接続する第1車線を合流区間に向かって走行する本線走行車両の位置と速度を計測する本線車両検出部(101)と、合流車線の路側に設置され、合流車線を合流区間に向かって走行する合流車線走行車両の位置と速度を計測する合流車両検出部(201)と、それぞれの計測結果から、本線走行車両および合流車線走行車両のそれぞれについて合流区間への到達時刻を予測し、予測したそれぞれの到達時刻の差分の絶対値が第1許容値以上を確保できていない場合には、本線走行車両に対して第1車線から合流車線と接続していない隣接車線への車線変更指示を出力する第1走行支援処理部(103、203、207)とを備える。【選択図】図1
