Urban traffic is made of a variety of mobility modes that have to be taken into account to explore the impact of catastrophic event. From individual mobility behaviors to macroscopic traffic dynamics, agent-based modeling provides an interesting conceptual framework to study this question. Unfortunately, most proposals in the domain do not provide any simple way to model these multi-modal trajectories, and thus fell short at simulating in a credible way the outcomes of a catastrophic event, like natural or industrial hazards. This paper presents an agent-based framework implemented with the GAMA modeling platform that aims at overcoming this lack. An application of this model for the study of flood crisis in a district of Hanoi (Vietnam) is presented.

An Agent-Based Co-modeling Approach to Simulate the Evacuation of a Population in the Context of a Realistic Flooding Event: A Case Study in Hanoi (Vietnam)

“…More recently, the 2008 off-season heavy rain in the North and North Central Coast surpassed all expectations and caused a historic flood in Hanoi [40]. These heavy rains are considered a record rainfall in the last 100 years (in 2018) and killed 17 people in the capital of Vietnam 13 . The damages have impacted nearly 13,000 households along the dike, flooding most houses around the Red River and tributaries.…”

“…The key entity of the model is nevertheless the agents representing human beings evacuating the area, with their heterogeneity in terms of individual behavior and social characteristics. The model has been built upon a previous model of mobility in Rouen (France) [18] and extended to several case studies of urban evacuation including the Vietnamese case study of Phuc Xa (Hanoi) [13]. Social and spatial features of the model.…”

“…when people evacuate by themselves. In [13], we thus investigate dry pedestrian and two wheels evacuation, with a simplistic alert system (everyone is alerted at once) to study the expected time to empty the area.…”

Experimenting the Impact of Pedestrianisation on Urban Pollution Using Tangible Agent-Based Simulations: Application to Hoan Kiem District, Hanoi, Vietnam

“…Modelling of traffic (in particular in an urban context) is now a widely spread approach to optimize traffic flow, reduce traffic jams or improve infrastructures, and help urban planning. [16] or [6] identified three main modelling approaches, mainly related to the modelling scale 7 .…”

“…ABMs have now a wide variety of applications, from physical and life sciences to economics and social sciences. Such agent-based models has been developed for example for evacuation using vehicles [7] or to investigate various mobility means [12]. Other advantages of ABMs are their flexibility and expressivity, e.g.…”
