The understanding of the pedestrian behavior in the crowd is indispensable for the assessment of urban layout and various approaches are reported for evaluating the safety of the social infrastructures. In this paper, a simulation model of pedestrian flow is introduced based on the Mixed Logical Dynamical (MLD) system approach. The effect of personal space is newly investigated from the viewpoint of the path-planning and an alternative pedestrian flow model is proposed based on the MLD system description. The feature of the proposed model is illustrated with typical simulations and the relation between the congestion and the effect of personal spaces is evaluated in the evacuation and bi-directional flows.
