中文摘要：

以视域引导行为准则为理论基础,以智能体（Agent）模拟为技术,在城市开空间中计算各点的视域参数,智能体根据视域参数选择运动方向,形成城市人流运动系统,来描述、模拟和预测城市空间中的人流运动及其相应的设施分布。

英文摘要：

Based on the visual affordance theory and the technique of Agent simulation,we develop the framework of Agent simulation system in urban system.The visibility parameters of viewpoints in urban space are pre-calculated to conduct the movement direction of Agents,and the pedestrian flows are formed when the Agents＇ movements achieve a stable state.We illustrate the system with an example to describe,simulate and predict the pedestrian flow in urban space.
