摘要

交通基础设施供应不足往往被视为全球城市实现可持续未来的障碍。这些障碍往往导致谁能受益于可持续交通机遇,谁不能受益于可持续交通机遇的严重不平等现象长期存在。本研究引入了一套新的二维指标,融合了供应和需求要素,以识别可持续交通公平方面的障碍和不平衡。这些可达性指标是针对公共汽车、铁路和自行车基础设施制定的,考虑了行政区域与优质交通基础设施的邻近程度以及特定模式的需求,以明确识别基础设施供应不足以支持当地人口的地区。我们介绍了利物浦城市地区的政策案例研究,展示了如何在分析框架中使用这些指标来支持长期的转型城市规划。特别是,这些指标揭示了可持续交通需求大于供给的政策优先领域,以及多种交通不平等现象在空间上相互交织的街区,突出了对特定类型基础设施投资的需求,以促进可持续交通的公平性(如更频繁的服务、更多的自行车道)。我们的框架为改善城市系统的决策奠定了基础,通过在小区域层面制定特定模式的可持续交通指标,首次协调了供需要素。

Developing two-dimensional indicators of transport demand and supply to promote sustainable transportation equity

Inadequate supply of transport infrastructure is often seen as a barrier to a sustainable future for cities globally. Such barriers often perpetuate significant inequalities in who can and who cannot benefit from sustainable transport opportunities, and as a result there is momentum for transformative urban planning to promote sustainable transportation equity. This study introduces a new set of two-dimensional indicators, merging elements of supply and demand, to identify barriers and imbalances in sustainable transport equity. The accessibility indicators, which are generated for bus, rail, and cycle infrastructure, consider the proximity of administrative areas to good quality transport infrastructure, as well as mode-specific demand, to clearly identify areas where the supply of infrastructure is inadequate to support local populations. We present a policy case study for Liverpool City Region, which demonstrates how these indicators can be used in an analytical framework to support transformative urban planning in long-term. In particular, the indicators reveal policy priority areas where demand for sustainable transport is greater than supply, as well as neighbourhoods where multiple transport inequalities are intersecting spatially, highlighting the need for specific types of infrastructure investment to promote sustainable transport equity (e.g. more frequent services, additional cycle paths). Our framework lays the foundations for improved decision-making in urban systems, through development of mode-specific sustainable transport indicators at small area levels, which harmonise elements of supply and demand for the first time.

期刊介绍: Computers, Environment and Urban Systemsis an interdisciplinary journal publishing cutting-edge and innovative computer-based research on environmental and urban systems, that privileges the geospatial perspective. The journal welcomes original high quality scholarship of a theoretical, applied or technological nature, and provides a stimulating presentation of perspectives, research developments, overviews of important new technologies and uses of major computational, information-based, and visualization innovations. Applied and theoretical contributions demonstrate the scope of computer-based analysis fostering a better understanding of environmental and urban systems, their spatial scope and their dynamics.
