新加坡不同地区公共交通可达性与土地利用模式分析
Analysis of public transport (in)accessibility and land-use pattern in different areas in Singapore
摘要：
随着越来越多的人继续生活在全球高度城市化的地区，可靠的设施和服务的可达性在可持续发展中发挥着至关重要的作用。解决这一问题的挑战之一是在整个城市系统中一致和平等地提供公共服务，包括为居民提供交通服务。在这项研究中，使用一种新的计算方法相结合的几何分析和信息理论的措施，我们分析了公共交通的交通节点（站）的空间覆盖范围和服务质量在这些节点在不同地区的可达性。此外，使用网络聚类程序，我们还分析了这些地区的土地利用模式，并将其与公共交通可达性。以新加坡为例，我们发现CBD区域的商业区具有良好的可达性，住宅区也具有良好到非常好的可达性。然而，并不是每个住宅区都是平等的。虽然这些地区的站点空间覆盖率非常好，但服务质量表明不同地区之间存在很大差异，与城邦西部和北部的其他地区相比，中部和东部地区之间的差异很大。我们相信，这种分析可以很好地了解整个城市系统的公共交通服务的现状，其差异将为未来的发展计划提供有价值和可操作的见解。
英文摘要：
As more and more people continue to live in highly urbanised areas across the globe, reliable accessibility to amenities and services plays a vital role in sustainable development. One of the challenges in addressing this issue is the consistent and equal provision of public services, including transport for residents across the urban system. In this study, using a novel computational method combining geometrical analysis and information-theoretic measures, we analyse the accessibility to public transport in terms of the spatial coverage of the transport nodes (stops) and the quality of service at these nodes across different areas. Furthermore, using a network clustering procedure, we also characterise the land-use pattern of those areas and relate that to their public transport accessibility. Using Singapore as a case study, we find that the commercial areas in the CBD area expectedly have excellent accessibility and the residential areas also have good to very good accessibility. However, not every residential area is equally accessible. While the spatial coverage of stops in these areas is very good, the quality of service indicates substantial variation among different regions, with high contrast between the central and eastern areas compared to the others in the west and north of the city-state. We believe this kind of analysis could yield a good understanding of the current level of public transport services across the urban system, and their disparity will provide valuable and actionable insights into the future development plans.
