基础设施网络在支持现代城市活动方面发挥着关键作用。未来的技术将需要氢燃料管道和量子互联网网络等网络，这些网络应该是可行和可持续的。本研究提出了一种方法，通过一个具有成本效益的网络连接给定的需求点，该网络具有较低的总长度，从而实现较低的建设成本和较低的总绕路率，从而实现较高的运营效率。该方法通过模拟人类在绿地上行走轨迹的叠加，从头开始配置网络。由于行人在短路径和其他人走过的路径上行走的自组织，步行轨道预计将具有成本效益。由此产生的网络与被认为具有成本效益的接近图相当或更具成本效益，并且具有与之相似或不同的几何特征。该方法需要两个主要参数：初始行走阻力和地面植被恢复速度。大量具有不同参数的网络近似于成本和效率之间的帕累托解。增加任何一个参数都会产生一个总长度较小、总绕路率较大的网络。这种可调性便于决策者面对建设成本和运营效益的约束。
Infrastructure networks play a key role in supporting modern city activities. Future technologies will require networks such as hydrogen fuel pipelines and quantum internet networks, which should be feasible and sustainable. This study proposes a method that connects given demand points by a cost-effective network, which has a low total length that enables a low construction cost and a low total detour rate that leads to high operational effectiveness. The proposed method configures the network from scratch by mimicking human walking track superposition on a green space. Walking tracks are expected to be cost-effective because of the self-organization of pedestrians walking on a short path and a path on which others have walked. The resulting networks are equivalent to or more cost-effective than proximity graphs considered cost-effective and have geometric features similar to and different from them. The method requires two dominant parameters: initial walking resistance and ground vegetation recovery speed. A large number of networks with varying parameters approximate Pareto solutions between cost and effectiveness. Increasing either parameter generates a network with a smaller total length and a larger total detour rate. This adjustability is convenient for decision-makers faced with constraints of the construction cost and operational effectiveness.
