Abstract

In this study, it is tried to simulate the behavior of pedestrians by using Social Force model, which is one of the presented model in the microscopic simulation. Because of the fact that this model is close to the real world, its results are more realistic. The aim of this study is to evaluate this model in Tehran’s sidewalks. In order to do this, sidewalks of 22 districts of Tehran were observed, and in the end, 6 districts (1, 4, 13, 16, 19, 22) were chosen since they had better conditions for shooting films. The procedure was that the real behavior of people was considered using the films, then, the data related to velocity and density were extracted. Based on the results achieved from statistical analysis, the Correlation coefficient between the data of the field study and modeling the velocity and density parameters are 0.916 and 0.907 which show an acceptable level of Correlation between the field study and the simulation. Moreover, based on the linear regression analysis done in the SPSS software program, it was observed that the variable constant amount in both velocity and density parameters equals to zero and the amount of the independent variable for the velocity parameter equals to 0.956 and for the density parameter equals 1.03. Also, the adjusted R square coefficient of the velocity parameter is 0.839 and for the density parameter is 0.870.
