基于城市道路网络脆弱性的小区开放策略研究

摘要

In this paper, through investigating the influence of the open-up degree, position and scale of a residential community on the fragility of the urban road network, we proposed some opinions for reference in the open-up initiative of the residential communities. Specifically, we proposed to make the nodal variance of the network the index to evaluate the fragility of the urban road network, and then through the MATLAB software, established the model for connecting the road network of the open communities into the urban road network. Next, under different connecting strategies, we conducted the simulation experiment and analyzed the findings.%通过研究开放小区开放程度、小区位置、小区规模三个方面对城市道路网络脆弱性的影响,为小区开放规划建设提出参考意见.提出将网络节点度方差作为城市道路网络脆弱性评价指标,通过MATLAB软件建立开放小区路网接入城市道路网络连接模型.在不同连接策略下进行仿真实验,实验结果显示小区路网接入节点越多、接入节点度越小、小区路网结构越复杂,城市道路网络节点度方差越小.从降低城市道路网络脆弱性角度为不同小区制定了开放策略.
