Conflicts between crowds are considered to be critical sources of safety incidents, and choosing a side is a common strategy for conflict resolution. Here, circle antipode experiments, which create significant conflicts and symmetric scenarios, were applied for the investigation of side preference behaviors. In the experiments, more participants (around 70%) preferred to reach the destination from the right side. The statistical analyses revealed that the pedestrian side choice involved a sophisticated mechanism, while factors such as handedness, gender, and height had no significant impacts. Further empirical investigations showed that most pedestrians actually make their side choices at the beginning, and selecting the dominant side can improve the individual movement efficiency. To reproduce realistic side choice results, a Voronoi-diagram-based model with a normally distributed side preference parameter was formulated and calibrated, and the simulation results proved the feasibility of the modified model in circle antipode experiments and other common situations.

人群之间的冲突被认为是安全事件的关键来源，选择一方是解决冲突的常见策略。在这里，圈对映体实验产生了显着的冲突和对称情况，被用于副偏好行为的研究。在实验中，更多的参与者（大约70％）更愿意从右侧到达目的地。统计分析表明，行人一侧的选择涉及复杂的机制，而诸如惯性，性别和身高等因素则没有重大影响。进一步的实证研究表明，大多数行人实际上是在开始时就做出了侧边选择，而选择优势侧边可以提高个体的运动效率。为了重现现实的选择结果，
