城市可达性与设施分布规律的解构

Deconstructing laws of accessibility and facility distribution in cities

Yanyan Xu, Luis E. Olmos, Sofiane Abbar, Marta C. Gonzalez

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。新的城市规划模式必须成为我们未来路线图的核心。在那里,居民可以在几分钟内通过自行车或步行获得他们的基本生活需求。在这项工作中,我们提出了新的见解之间的相互作用的分布设施和人口,最大限度地提高现有的道路网络的可达性。六个城市的结果表明,通过重新分配设施,旅行费用可以减少一半。在最优方案中,平均出行距离可以建模为设施数量和人口密度的函数形式。作为这一发现的应用,它是可能的,以达到一个理想的平均旅行距离给定的城市人口分布估计所需的设施的数量。

英文摘要:

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.
