基于行人仿真的历史文化街区步行空间优化策略研究

Research on the Strategies for the Optimization of Pedestrian Space in Historical and Cultural Blocks Based on Pedestrian Simulation

由于缺乏适应新时代背景的理论支持和科学指导,传统历史文化街区内步行空间规划难以完全满足当代城市发展的需求。随着行人仿真技术的不断进步,能够对步行空间与行人行为之间的关系进行更精确的定量分析,从而实现步行空间设计的优化。文章通过调研、收集昙华林历史文化街区的基础现状和公共服务设施分布等信息,并获取了行人步行特征及空间热力特征等数据。运用基于社会力模型的Legion行人仿真软件对这些数据进行建模、仿真模拟、量化分析。研究结果显示,通过优化后的步行空间设计,能够实现行人流量的均衡分布,减少拥堵点的出现,并能有效引导人流到历史建筑等重要景点。

Due to the lack of theoretical support and scientific guidance adapted to the context of the new era,it is difficult for the pedestrian space planning in traditional historical and cultural neighborhoods to fully meet the needs of contemporary urban development.With the continuous advancement of pedestrian simulation technology,it is possible to carry out a more accurate quantitative analysis on the relationship between pedestrian space and pedestrian behavior,so as to optimize the design of pedestrian space.The paper collects the information on the basic status and distribution of public service facilities in Tanhualin historical and cultural neighborhood through investigation,and obtains data on pedestrian walking characteristics and spatial thermal characteristics.The Legion pedestrian simulation software based on the social force model was used to model,simulate and quantitatively analyze these data. The results show that the optimized pedestrian space design can achieve a balanced distribution of pedestrian flow, reduce the emergence of congestion points, and effectively guide the pedestrian flow to the historical buildings and other important attractions.
