The invention discloses an urban road network mechanism association planning method based on a complex network sandpile model. According to the method, a sandpile avalanche model in combination with acomplex network theory is provided, the congestion distribution situation of an urban traffic network is analyzed, the congestion action mechanism between traffic roads is known, and defects existingin the urban road design and planning process are found. According to the method, an urban road network mechanism correlation model is established, the traffic dispersion capacity of roads and dynamic factors playing a correlation role in congestion are considered, and the factors are reasonably considered into the correlation model through normalization and other operations; an evolution mechanism process of an urban road is simulated through system simulation, and an evolution propagation process of congestion after urban road congestion is presented by means of an analysis process of a sandpile model in a complex network theory, so that the rationality of design and planning of the whole urban road network is integrally understood, and a scientific basis is provided for further optimization of urban road planning.
本发明公开了一种基于复杂网络沙堆模型的城市路网机理关联规划方法。该方法提出了一种结合复杂网络理论中“沙堆雪崩”模型,分析城市交通网络的“拥堵”分布情况,帮助了解交通道路之间的拥堵作用机理,发现在城市道路的设计、规划过程中存在的缺陷。该方法首先建立城市道路网机理关联模型,考虑道路自身的交通疏导能力,以及对拥堵起相关性作用的动态因素,通过归一化等操作,合理的将这些因素考虑到该关联模型中;通过系统仿真,模拟出城市道路的演化机理过程,借助于复杂网络理论中沙堆模型的分析过程,呈现城市道路拥堵后,拥堵的演化传播过程,进而从整体了解整个城市道路网设计、规划的合理性,为城市道路规划的进一步优化提供科学依据。
