ABSTRACT:
A paradigm to improve the quality of pedestrian movement by considering their interactions in the microscopic level is introduced. By this approach, design of pedestrian facilities is not merely space allocation but it can also utilize other form of flow controls in space, time and direction. Although microscopic pedestrian analysis exists, the microscopic pedestrian data collection has not been developed. Once such microscopic data is collected, another problem on how to measure the flow performance from the microscopic data collection arises. This paper describes how data reduction can be made to obtain pedestrian flow performances. The automation of microscopic pedestrian data from video files is also explained. The video data is converted into numbers as a NTXY database. Following this conversion, the rest of the process can be done using computers that reduce the processing cost and speed, and improve accuracy. The data reduction of NTXY database into well-established traffic flow variables and some prominent flow performance was formulated. It was confirmed that the procedures described have significant potential to automate measurement of both microscopic and macroscopic pedestrian flow performances.
