Dynamic Cell Transmission–Based Pedestrian Model with Multidirectional Flows and Strategic Route Choices

Abstract

This paper proposes a framework for a dynamic pedestrian model with a strategic route choice model and multidirectional flow propagation. In an open urban area, a massive number of possible pedestrian paths can be defined. However, psychologically the pedestrian does not consider all these paths as distinct options. Thus, this paper assumes the pedestrian chooses a series of consecutive subareas to traverse in the first instance. Then, the model allocates the actual flows on each detailed route on the basis of an assumption of dynamic user optimum. Combining these two stages, the model assumes a hierarchical decision of pedestrians’ route choice. A modified cell transmission model (CTM) is adopted to represent the physical phenomena of dynamic propagation of the pedestrian flows. A key difference from the original CTM is that the pedestrian flow is multidirectional by nature. This paper proposes a modified CTM to consider the multidirectional movement. The proposed modified CTM is then assessed with a test case.

A reactive dynamic continuum user equilibrium model for bi-directional pedestrian flows

“…In most such instances, the fatalities and injuries are caused by the behavior of the crowd itself, and this issue is receiving increased attention from scientists. Many crowd-flow models (e.g., [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]) have been developed to investigate the complex dynamics and behavior of pedestrians in various situations.…”

Modeling, Evaluation, and Scale on Artificial Pedestrians

“…The pedestrian flow between two adjacent cells is governed by the fundamental diagram. The work by Asano et al [2007] adapts the original formulation to the multi-directional flows situations, such as crossings. The work by Guo et al [2011] proposes the creation of a cell potential to generate the flow between adjacent cells.…”

“…The shape and area of cells can be chosen freely. Typically, cells of an area of approximately 10 m 2 are used (Asano et al, 2007;Guo et al, 2011). A route is given by an origin and a destination, and a subset of cells (illustrated by shaded cells).…”
