TRAFFIC GUIDANCE SYSTEM AND TRAFFIC GUIDANCE METHOD
To accurately and efficiently detect the lane change performed due to roadwork, etc., of a vehicle approaching an alternating traffic section, to thereby perform appropriate traffic guidance.SOLUTION: When a vehicle C1 approaches an alternating traffic section while a traffic light 25A is green denoting an access permission state, an approaching vehicle detection sensor 29A detects this vehicle C1 and measures the speed v and distance x of the vehicle C1 (S1). When the vehicle C1 runs over the detection range of the approaching vehicle detection sensor 29A, a time T1 that is needed until the vehicle C1 passes through the approaching vehicle detection sensor 29A and a time T2 that is needed for passing through the alternating traffic section are calculated using the speed v and distance x and distance d of the alternating traffic section which are last measured (S2). The traffic light 25A is changed to red denoting a no-entry state after being kept lighted green until the T1 elapses (S3), and a traffic light 25B is changed to green after being kept lighted red until T1+T2 elapses (S4).SELECTED DRAWING: Figure 1
【課題】道路工事等に伴う交互通行区間へ接近する車両の車線変更を正確かつ効率的に検出して適正な交通誘導を行うことを課題とする。【解決手段】信号機２５Ａが進入許可状態である青信号の場合に、車両Ｃ１が交互通行区間に接近してきたならば、接近車両検知センサ２９Ａは、この車両Ｃ１を検知して車両Ｃ１の速度ｖ及び距離ｘを計測する（Ｓ１）。車両Ｃ１が接近車両検知センサ２９Ａの検知範囲からはみ出した場合には、直近に計測した速度ｖ、距離ｘ及び交互通行区間距離ｄを用いて、車両Ｃ１が接近車両検知センサ２９Ａを通過するまでに必要な時間Ｔ１及び交互通行区間を通過するために必要な時間Ｔ２を算出する（Ｓ２）。Ｔ１が経過するまで信号機２５Ａの青信号を維持した後に進入禁止状態である赤信号に切り替え（Ｓ３）、Ｔ１＋Ｔ２経過するまで信号機２５Ｂの赤信号を維持した後に青信号に切り替える（Ｓ４）。【選択図】図１
