  To deal with many pedestrian data, automatic data collection is needed. This
paper describes how to automate the microscopic pedestrian flow data collection
from video files. The study is restricted only to pedestrians without
considering vehicular - pedestrian interaction. Pedestrian tracking system
consists of three sub-systems, which calculates the image processing, object
tracking and traffic flow variables. The system receives input of stacks of
images and parameters. The first sub-system performs Image Processing analysis
while the second sub-system carries out the tracking of pedestrians by matching
the features and tracing the pedestrian numbers frame by frame. The last
sub-system deals with a NTXY database to calculate the pedestrian traffic-flow
characteristic such as flow rate, speed and area module. Comparison with manual
data collection method confirmed that the procedures described have significant
potential to automate the data collection of both microscopic and macroscopic
pedestrian flow variables.
