The pedestrian model study has been spotlighted in the field of transportation recently urban complex devel-oped huge yet very sophisticated in which resulted the emergence of heavy pedestrian traffics within gigantic infrastructure. It leads to a demand on developing a more efficient pedestrian movement model. However, it is hard to find a proper model adequately taking into account the human perception response to obstacles. In order to model the pedestrian movement, it is necessary to consider the activity agenda of pedestrians and incorporate the perception interactions between pedestrians and their surrounding environments. Majority of existing models are macroscopic and force-based, due to relatively low computational time and less control parameters without additional alternatives in the simulation. In these models, there is no assumption of perception processes for walking since there are many limitations to implement in reality. To speculate reasonable results, a proper perception process is required to explain a decision process with their visual range simultaneously. Macroscopic models are not dealing with individuals, as well as force models are not adjustable to represent perception reactions since human is assumed as a physical particle. On the other hand, microscopic and route choice models deal with individuals yet most of simulation principles in these models are stochastic. Therefore, they do not take responsibility to avoid urgent collisions. With the above setbacks of existing models in mind, this study was conducted on a pedestrian movement behavior model that can represent the perception process in micro level strategies by combining logical route choices to the long range with the immediate response to the short range. This route choice model interprets the walking process as a sequence of choices over time based on the assumption that pedestrians make own decisions to avoid collisions and to minimize the delay time when pedestrians secu...
