Traffic direction change amount survey report automatic generation system

摘要

PROBLEM TO BE SOLVED: To provide an automatic traffic direction change amount survey report generation system capable of generating a report in real time and improving the accuracy of object tracking. A traffic direction change amount survey report automatic generation system (10) includes an image acquisition device (12) and a host (20). The image acquisition device 12 acquires an image of an intersection, which is a measurement area, and transmits it to the host 20. The host 20 sets an intersection determination line and an altitude determination area in the measurement area, trains a deep learning model, and analyzes the type and position of the vehicle. After calculating the trajectory data of the vehicle, the traveling direction of the vehicle is determined based on the determination line. When continuous frame loss occurs in the trajectory data, the altitude determination area is used to correct the vehicle entry / exit direction, data processing is performed on the entry / exit direction and the trajectory data, and a direction change amount report is generated.
