Abstract:

Taking the collision avoidance in the pedestrian simulation as the research object, a concept of blockade-angle was introduced. The blockade area that needs to circumambulate by the pedestrian was defined by the introduced blockade-angle of the impediment to the on-going pedestrian. The circumambulation route of the pedestrian around the static impediment was chosen based on the shortest route principle. Considering the right-hand walking custom in China, the colliscon avoidance of the counter-directional pedestrians was realized by reducing the priority of the end-side of the blockdae-angle. It was suggested that for the special case of a pedestrian being limited by all sides of the blockade-angle, the question that whether the pedestrian should move continually and how much is his speed was depended on the speed and direction of the nearest pedestrian on the target direction. The realizing process of the proposed collision avoidance method was simulated, the results showed that this method does not require the complicated calibration process, the modeling process in the pedestrian simulation is also greatly simplified.
