Mobility Model of Theme Park Visitors

Introduction

Theme park mobility model (TP) is a scenario-specific human walk model. In our model, the non-determinism of movement decisions of theme park visitors is combined with deterministic behavior of attractions. The attractions are categorized as rides, restaurants, and live shows. The time spent at these attractions are computed using queueing-theoretic models.

The realism of the model is evaluated through extensive simulations and compared with existing mobility models and the GPS traces of theme park visitors. The results show that our proposed model provides a better match to the real-world data (from CRAWDAD archive) compared to current state-of-the-art movement models.


Overview

Recent advances in mobile devices enabled the increased popularity and usage of mobile applications. The realistic modeling of human movement has significant importance for the performance assessment of mobile wireless systems.

Motivation

  • Mobility models drastically change performance results of networks
  • Early models based on random walks are very coarse approximations
  • Focusing on human walks due to limited vehicle use in theme parks

Outcomes of our model are useful for

  • Performance evaluation of mobile applications
  • Theme park administration

Contributions

  • A novel scenario-specific mobility model
  • Representing the social behavior of gathering in attractions, spending time in queues, and the least-action principle
  • The outcomes are synthetically generated mobility traces that are useful for simulations
  • The best statistical match to the GPS traces amongst the tested synthetic models
