Self-organized pattern formation of pedestrian crowds, such as lane formation, turbulent movement, and human trails, has been subject to interest of various disciplines. The microscopic pedestrian flow models have described the pedestrian motions in terms of driving, repulsive, and attractive forces. However, little attention has been paid to attractive interactions between pedestrians and objects including shopping displays and museum exhibits. In reality, such attractive interactions may lead to impulse stop behavior; pedestrian stop walking to destinations and join the attractions for certain amount of time. This study investigates the impact of attractive force on pedestrian flow by devising the social force model with attractive forces. Changing attractive force parameters yields radical transition between two distinct aggregate patterns. Relaxed pedestrian flow is observed when attractive interaction is weak. On the other hand, strong attractive interaction reveals clustering around the attractive objects, although pedestrians intended to walk to destinations with their desired speed. The proposed approach provides a useful framework to improve pedestrian facilities in shopping centers and museums.
