论文摘要
汽车时代通过昂贵的旅行和明显的环境影响严重降低了城市生活的质量。在未来几年中，新的城市规划范式必须是我们路线图的核心。在几分钟之内，居民可以通过自行车或步行来获得基本的生活需求。在这项工作中，我们介绍了设施分布与人口分布之间相互作用的新颖见解，这些分布与现有道路网络的可及性最大化。六个城市的结果表明，通过重新分配设施可以将旅行成本降低一半。在最佳情况下，平均行程距离可以建模为设施数量和人口密度的功能形式。作为这一发现的应用，鉴于城市中的人口分布，可以估计达到所需的平均旅行距离所需的设施数量。
The era of the automobile has seriously degraded the quality of urban life through costly travel and visible environmental effects. A new urban planning paradigm must be at the heart of our roadmap for the years to come. The one where, within minutes, inhabitants can access their basic living needs by bike or by foot. In this work, we present novel insights of the interplay between the distributions of facilities and population that maximize accessibility over the existing road networks. Results in six cities reveal that travel costs could be reduced in half through redistributing facilities. In the optimal scenario, the average travel distance can be modeled as a functional form of the number of facilities and the population density. As an application of this finding, it is possible to estimate the number of facilities needed for reaching a desired average travel distance given the population distribution in a city.
