| dc.description.abstract | The Social Force Model is one of the most successful microscopic pedestrian models that represent the well-organized phenomena of the pedestrian flow. However, the pedestrians‟ abilities to make decisions in normal and emergency situations have not been incorporated properly into the model. In normal situations, the pedestrians were found to be short-sighted in avoiding some anticipated blocked situations. In emergency situations, several realistic mechanisms of the decision making capability do not appear within relevant simulations. In this research, the decision-making capability of the independent pedestrians is enhanced. First, an extension of the model by granting the pedestrians the ability to investigate the behaviors beyond their own perception areas is made. The new model considers the density factor inside such areas and models its effect on the pedestrians' decisions to eliminate the unrealistic behavior. Second, in evacuation situations, an improvement of selecting an exit from the set of exits available in the physical environment is made by providing the pedestrians with an assessment ability of their physical environment and the corresponding dynamic behavior of the others. Simulation of normal and emergency situations are performed to validate the work qualitatively by tracing the behavior of the simulated pedestrians and studying the impact of this behavior on the realism of the original model. A comparison between the original and the extended models is done. Further work to calibrate crowd –related parameters to reproduce empirical data is also made. | en_US |
