摘要翻译:
城市街道模式形成平面网络,其经验性质不能用规则网格或Voronoi网格等简单模型来解释。最近在经验上发现了不同城市之间惊人的统计规律,这表明一个一般性的、独立于细节的机制可能在起作用。我们提出了一个基于局部优化过程的简单模型,并结合了以前在叶型形成研究中提出的思想。该模型的统计性质与观察到的经验模式符合得很好。因此,我们的结果表明,在缺乏全球设计策略的情况下,许多不同交通网络的演化确实遵循一个简单的普遍机制。

英文摘要:
Urban streets patterns form planar networks whose empirical properties cannot be accounted for by simple models such as regular grids or Voronoi tesselations. Striking statistical regularities across different cities have been recently empirically found, suggesting that a general and details-independent mechanism may be in action. We propose a simple model based on a local optimization process combined with ideas previously proposed in studies of leaf pattern formation. The statistical properties of this model are in good agreement with the observed empirical patterns. Our results thus suggests that in the absence of a global design strategy, the evolution of many different transportation networks indeed follow a simple universal mechanism.
