Measuring Microscopic Flow Performance for Pedestrians

چکیده
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.

mistakes in the earlier draft of this manuscript and for her love and encouragement. Microscopic pedestrian studies consider detailed interaction of pedestrians to control their movement in pedestrian traffic flow. The tools to collect the microscopic data and to analyze microscopic pedestrian flow are still very much in its infancy. The microscopic pedestrian flow characteristics need to be un...

Introduction Various methods to automate traffic data collection have recently been developed by many researchers. A macroscopic data collection through image processing has been proposed [1]. For microscopic traffic flow data, such as individual speed and time or distance headway, tracking of individual movement is needed. The tracking algorithms for pedestrian or vehicle have been developed t...

Travels within the city are done in different ways, by vehicle or on foot. Thus, inevitably, a part of the travel is always done on foot. Since intersections as traffic nodes are determinant factor in transportation network capacity, any disruption in them leads to severe reduction in network capacity. Unfortunately, pedestrian behavior has received little attention in Iran. While this is a ver...
متن کاملA generic and hybrid approach for pedestrian dynamics to couple cellular automata with network flow models
Large pedestrian dynamics scenarios are difficult to simulate by models with high spatial resolution in reasonable time, due to high computational costs. Possible solutions are hybrid approaches, which combine models of different spatial scales. On the macroscopic scale, network flow models are used to model pedestrian dynamics. These models reduce the scenario to a simple network of nodes and ...
