| dc.description.abstract | The Social Force Model (SFM) is the most recent form of pedestrian model which is widely used in computer simulation software, as this model is more realistic. Many modifications have been done to improvise the SFM. One of them is a self-stopping mechanism introduced by earlier researchers where a respect factor is used to determine the self-stopping mechanism. The respect factor determines the respect area which is the area for pedestrians to walk at their own preferred speed. In this thesis, the constant respect factor is modified to obtain a better fundamental diagram. Also, the new dynamic respect factor is used to investigate different situations in simulating pedestrians. One of the situations involves elderly pedestrians who walk at a slower speed needs wider walking space. Another modification in the dynamic respect factor is to simulate pedestrians walking in multi-directions. The action of “respect” between pedestrians is incorporated into this modification. The visual simulations are analyzed to study its efficiency. The characteristic of age and gender factor is incorporated into the multi-directional walkway to produce a simulation which is close to the real-life crowd. The application of the normal Social Force Model in computer simulation models is also discussed here. The pedestrian simulation computer software, SimWalk, is used to study the simulation of pedestrian flow. The study of circumambulation of the Ka’aba is taken as an illustrative example, where performing Tawaf is one of the rituals when performing the Hajj. The pilgrims face two main problems in this situation. The first is the overflowing of the pilgrims during the Hajj season. | en_US |
