Abstract-In this paper, we propose a scenario-specific human mobility model (TP-D) in theme parks. We focus on the disaster scenarios which have significant differences compared to the ordinary mobility behavior of the theme park visitors. The main goal of the theme park operation in disaster scenarios is the evacuation of the visitors from the disaster areas.We first model theme park as a combination of roads, obstacles, lands, and disaster events. We use real theme park maps for generating the theme park models. We incorporate the macro and micro mobility behaviors of the visitors in theme park models. We use the social force concept to model the impact of social interactions on the micro mobility of the visitors. Macro mobility decisions are based on the local knowledge of the visitors, the waypoints, and the disaster events. We analyze and compare the results of the simulation of our model with simulations of currently used models and real-world GPS traces of visitor movement.
I. INTRODUCTIONRealistic modeling and accurate simulation of the mobility in theme parks allows us to evaluate performance of the networks for event coverage [1], the opportunistic communication [2], and evacuation of the visitors from disaster areas.Human mobility is based on the combinations of many factors including deterministic and non-deterministic decisions which depend on the scenario. Most commonly used simple mobility models such as random waypoint (RWP) model or generic human mobility models are not suitable to represent the human mobility behavior in many different application scenarios. There is a certain need for scenario-specific modeling for realistic simulations of human mobility. Therefore, we modeled visitor movements in theme parks in [3] to represent daily routine mobility of theme park visitors without any consideration of the disaster scenarios. However, in our model [3] and the other currently used theme park mobility models, the movement decisions of the visitors are based on visiting the attractions and exploring the park. Considering a disaster scenario, the movement decisions should be based on the security of visitors. The main goal of the theme park operation include finding easy ways to secure places and fast evacuation of the visitors from the disaster areas.We consider a wide range of disaster scenarios which may happen in theme parks. These scenarios include natural disasters such as tornado, fire, thunderstorm, hurricane, and earthquake. Moreover, terrorist attacks are man-made disasters which threaten human life especially in crowded places. Therefore, security of the theme parks has vital importance. The studies on disaster recovery and opportunistic communication networks have become major research interests due to their prospective contributions on the disaster management strategies. For instance, as an effect of a disaster, communication infrastructures which are pre-deployed in the disaster area may become unoperational. For this reason, communication
