             abstract = "The social force (SF) model has been successfully applied to the 
                         simulation of flows of pedestrians. Nevertheless, in some 
                         scenarios with low density, experiments show that the simulated 
                         individuals do not behave as expected, working as irrational 
                         particles rather than smart people. For example, by the means of 
                         the cited model, it is common to see many simulated individuals 
                         going several times straightly against columns, before finding a 
                         way to deviate and safely exit the room. Aiming to deal with such 
                         problems, this article proposes a way to provide the simulated 
                         pedestrians the ability of changing the direction of their 
                         displacement at reasonable times, in order to bypass eventually 
                         blocked or crowded near areas. To do so, it applies concepts from 
                         the lattice-gas model to the SF model. Experiments were driven in 
                         order to evaluate the proposed model. As results, it maintained 
                         the ability of the SF model to reproduce phenomena like the 
                         formation of arcs in evacuated one-door rooms. Focusing on the 
                         scenario with a column-blocked one-door room, the simulated 
                         pedestrians presented softer and more coherent trajectories, when 
                         compared to the pure SF model solution.",
