Autonomous tawaf crowd simulation

Crowd simulation is an exciting research area that has a wide range of applications in multiple fields such as: serious games, crowd management, facilities design, entertainment, research and development. One of the most famous approaches to simulate a large density crowd is by applying the social force model. This model can be successfully used to simulate agents’ movement in real-world scenarios realistically. Nevertheless, this is very simple and not suitable to simulate a complex pedestrian flow movement. Hence, this research proposes a new novel model for simulating the pilgrims’ movements circumambulating the Kaabah (Tawaf). These rituals are complex yet unique, due to its capacity, density, and various demographics backgrounds of the agents (pilgrims). It is also consist a certain set of rules and regulations that must be followed by the agents. Due to these rules, the Tawaf can introduce irregularities in the motion flow around the Kaabah. In order to make the simulations as close as possible to real world scenarios, each agent will be assigned with different attributes such as; age, gender and intention outlook. The three parameter mentioned above, are the main problem that need to be solved in this research in order to simulate a better crowd simulation than previous studies. The findings of this research will contribute greatly for Hajj management in term of controlling and optimizing the flow of pilgrims during Tawaf especially in the Hajj season. It is also have high contribution in Hajj training especially in developing a virtual Hajj training system. The virtual Hajj system can be used to teach and prepare the pilgrims before going to Mecca and perform the actual Hajj

Tawaf crowd simulation using social force model

This paper presents a crowd simulation system which simulates the movement of pilgrims in performing one of Hajj rituals, which is Tawaf. Tawaf is a unique case study due to its capacity and various set of pilgrims. Furthermore, the density of the crowd is extremely high. Tawaf also consist a certain set of rules and regulations that must be followed by the pilgrims. Social Force Model had been chosen to give each agent in the simulation a specific behavior to be followed. The algorithm also specifies how the agents interact with each other to generate collision free movements. To make the simulations as close as possible to real world scenarios, each agent varies in term of age, gender and behavior. The subjective evaluation of the system revealed that it can be used in pilgrim training before performing the actual Tawaf
