To provide a traffic flow measurement system for presenting results of traffic flow analysis to a user, capable of allowing the user to intuitively grasp the changing state of the moving body while viewing sensor images as the detection results of a sensor targeting a measurement area.SOLUTION: A traffic flow measurement server is configured to generate a behavior image of visualized time series data representing the changing situation of states (position, velocity, and acceleration) of the moving body based on results of traffic flow analysis processing, in particular, a trajectory line 411, a velocity line 412, and an acceleration line 413, and to generate a time-series display screen 401 in which the behavior image is superimposed on sensor images (a camera image 403, a lidar intensity image 404, and a lidar point cloud image 405) based on the sensor detection results, so as to display the screen on a user terminal.SELECTED DRAWING: Figure 24
【課題】交通流解析の結果をユーザに提示するにあたり、ユーザが、計測エリアを対象にしたセンサの検出結果としてのセンサ画像を閲覧しながら、移動体の状態の変化状況を直感的に把握できるようにする。【解決手段】交通流計測サーバが、交通流解析処理の結果に基づいて、移動体の状態(位置、速度、および加速度)の変化状況を表す時系列データを可視化した挙動画像、具体的には、軌跡ライン411、速度ライン412、および加速度ライン413を生成し、その挙動画像を、センサの検出結果に基づくセンサ画像(カメラ画像403、ライダー強度画像404、およびライダー点群画像405)上に重畳した時系列表示画面401を生成し、その画面をユーザ端末に表示させる。【選択図】図24
