街道视角的多智能体城市安全宜居度建模

Modeling of Multi-agent City Safety and Livability Based on Street Perspective

为解决环境及人类活动因素影响下的城市安全宜居问题,以深圳市福田区10个街道的实际数据为基础,结合Repast仿真平台和地理信息系统(geographic information system,GIS)建立基于多智能体的城市安全宜居度仿真模型;从街道视角模拟福田区未来20 a(年)城市安全发展的演变过程,用情景实例论证分析了福田区各个街道的城市安全宜居度、居民满意度和家庭搬迁行为的动态交互反馈机理。实验结果证实了多智能体模型在仿真模拟多因素影响下城市发展的有效性。

In order to solve the problem of urban safety livability under the influence of environmental and human activities,this paper builds a multi-agent model of city safety livability based on the data of ten streets in Futian District,Shenzhen.The model is realized by integrating geographic information system(GIS)with Repast simulation platform.With the model,we have simulated the evolution of urban safety development in Futian District in the next 20 years from the perspective of streets,and analyzed the dynamic interactive feedback mechanism of safety livability,resident satisfaction,and family relocation behavior of each street in Futian District.The simulation experiment proves that the multi-agent model is effective for predicting urban development under the influence of multiple factors.
