PROBLEM TO BE SOLVED: To provide a vehicle length measurement device for appropriately measuring a vehicle length of coupled vehicles by using a laser scanner.SOLUTION: When multiple vehicle bodies detected from scan data constitute coupled vehicles, a vehicle type discrimination device measures a length from the foremost end of a vehicle body positioned on the most downstream side in a lane direction among the multiple vehicle bodies to the rearmost end of a vehicle body positioned on the most upstream side in a lane direction among the multiple vehicle bodies as a length of one vehicle. When multiple vehicle bodies detected from scan data do not constitute coupled vehicles, the vehicle type discrimination device measures a length from the foremost end to the rearmost end of each vehicle body constituting the multiple vehicle bodies as a length of each independent vehicle.SELECTED DRAWING: Figure 4
【課題】レーザスキャナを用いて連結車両の車長を適切に計測する車長計測装置を提供する。【解決手段】車種判別装置は、スキャンデータから検出された複数の車体が連結車両を構成する場合に、複数の車体のうち最も車線方向下流側に位置する車体の最前端から複数の車体のうち最も車線方向上流側に位置する車体の最後端までの長さを、1つの車両の長さとして計測する。他方、車種判別装置は、スキャンデータから検出された複数の車体が連結車両を構成しない場合に、複数の車体を構成する各車体の最前端から最後端までの長さを、それぞれ別個の車両の長さとして計測する。【選択図】図4
