The Design and Application Research of Subway Train Passenger Travel Time Measuring Method
The time for passengers to walk is the time spent walking through a specific route in the station,which is used in the station passenger wind risk investigation,clearing model verification,and trial.Existing detection methods have over sampling or under sampling problems,oversampling reduces accuracy,and under sampling reduces recall.In order to improve the accuracy and recall rate,this paper proposes a walking time measurement method based on pedestrian tracking,which performs a single sampling according to the passenger trajectory,thereby avoiding over sampling and under sampling,and ultimately greatly improving the accuracy and recall of the measurement method.Sufficient experimental verification shows that the measurement method can achieve 98%accuracy and 52%recall rate when the camera angle is suitable,meeting the requirements of multiple services.
