factors in the development of urban Underground Space surrounding metro stations a case study of osaka japan
Tunnelling and Underground Space Technology, 2019Co-Authors: Jian Peng, Fangle Peng, Nobuyoshi Yabuki, Tomohiro FukudaAbstract:Abstract Most previous studies have simply revealed the relationship between urban Underground Space (UUS) potential and influential factors for a city but have not revealed the relationship for each metro station, or lack quantitative analyses of their relationship. Actually, it is essential to identify the relationship of UUS area (UUSA) and relative factors because UUS tends to be aggregated around metro stations. This study investigated the quantitative relationship between several candidate influential factors and the UUS distribution surrounding metro stations on two lines in Osaka, Japan. A correlation regression analysis showed that passenger flow rate and land price were highly related with UUSA. Although the land use index, floor area ratio, and transfer line number did not have significant linear relationships, the spatial distribution of land use was related with UUSA. We argue that Underground shopping malls should be constructed in station areas with high passenger flow rate, high land price, and large commercial plots. This model may be of great assistance to decision-makers owing to its realistic forecasts for UUS development.

a gis based evaluation method of Underground Space resources for urban spatial planning part 2 application
Tunnelling and Underground Space Technology, 2018Co-Authors: Jian Peng, Fangle PengAbstract:Abstract Urban Underground Space (UUS) has been playing an important role in the urban development in recent years. The evaluation for its potential becomes essential for urban spatial planning. Previous research emphasized the fundamental data, while this paper not only emphasized the data provided by related departments, but also took into consideration the gap and relation between UUS and urban spatial planning. To provide theoretical support for urban spatial planning, this paper studied a method for evaluating UUS. In this method, an index system for UUS resource evaluation was put forward and its analytical process was based on the Geographic Information System (GIS) and some mathematical tools, such as the analytic hierarchy process (AHP), the most unfavorable grading method (MUGM) and the exclusive method (EM). Then this method was applied to UUS Master Plans and Detailed Regulatory Planning in Chinese cities, and proved to be relatively practicable. The research outcomes are presented in the form of two papers, each with a different focus. Part 1 aims to introduce the evaluation methodology, including construction suitability evaluation & potential value evaluation & volume estimation. Part 2 reports on applications of the method to Chinese cities of Tongren and Changzhou. Part 2 demonstrated the UUS resource evaluation methodology for Tongren city and Changzhou city in China. In Tongren, the UUS construction suitability and resource’s comprehensive quality (RCQ) evaluation was implemented on an urban scale. Firstly, factors influencing the potential for UUS, including the area’s landforms, engineering geology, hydrogeology, site stability, existing subsurface construction conditions, urban location, and land use were collected and analyzed based on GIS. Furthermore, a combination of AHP, MUGM and EM techniques were used in the analysis. Then the UUS construction suitability and RCQ distribution were got. The UUS layout structure was finally obtained based on RCQ distribution figure. Meanwhile, this case study shows that the area used for UUS accounts for only 2% of the effective utilization area of the whole city based on the volume estimation model. While for Changzhou, existing construction evaluation at the parcel scale was implemented for one downtown area. A “four steps” method was proposed to calculate the influence depth of building foundations based on the geographical statistical analysis module of GIS with an interpolation method. Flexible application of the method, with the addition of local project experience, can make the planners definitely determine which part of the area can be exploited. A flow chart of existing construction evaluation is finally presented.

layout patterns of Underground Space comprehensive utilization around metro station for urban commercial area
GeoShanghai International Conference, 2018Co-Authors: Jian Peng, Fangle PengAbstract:In order to satisfy contemporary urban development requirements, it is essential to utilize urban Underground Space (UUS) effectively when planning new metropolitan subway (metro) stations, especially in commercial areas. Herein, two cases involving metro stations in commercial areas, the Xujiahui zone in Shanghai, China and the Namba zone in Osaka, Japan, are investigated with respect to land use and UUS utilization, after which their Underground Space distribution situations are summarized in terms of function and layout, and the differences between the two cases are discussed. Two kinds of comprehensive UUS utilization layout patterns are elucidated, i.e., station center layout and commercial street center layout. The station center layout emphasizes the smooth transfer of people between transportation modes, while the commercial street center layout emphasizes not only transportation transfer, but also more intensive commercial exploitation of Space under municipal roads and higher floor area ratios. Here, it should be noted that the former can transform to the latter as the city develops. Our study also shows that the development of UUS around metro stations in urban commercial areas is based on urban “function and layout” interaction characteristics, but the layout pattern may also be different depending on different national context.

Part 2 reports on applications of the method to Chinese cities of Tongren and Changzhou. Part 1 analyzed the concept behind and the process involved in the UUS spatial planning evaluation methodology, combining construction suitability evaluation & potential value evaluation & volume estimation. Based on the factors that influence the development and utilization of a UUS, an index system for UUS resource evaluation is presented. Its primary components are construction suitability (including landform, geology, hydrogeology and the existing construction situation) and potential value (including urban spatial location and land use function). Using AHP, MUGM and EM, the level of each index was quantified and overlaid based on GIS, and then the UUS evaluation output was obtained, such as construction suitability distribution, Resource’s comprehensive quality (RCQ) distribution, with manifestation styles of maps and tables. In this research, three models are proposed, including a construction suitability model, a comprehensive quality model and a volume estimation model. The construction suitability model can evaluate the construction difficulty or cost grade, while the comprehensive quality model can evaluate potential benefit grade of every part in the city. They reflect the formula “Quality = Potential − Cost” to some extent. On the other hand, the volume estimation model can calculate the urban indicators for UUS, which can give data support for urban spatial planning.

planning and implementation of Underground Space in chinese central business district cbd a case of shanghai hongqiao cbd
Tunnelling and Underground Space Technology, 2020Co-Authors: Fangle Peng, Yongkang Qiao, Jingwei Zhao, Jiachuan LiAbstract:Abstract The increasing latent demand for Underground Space has been adequately considered in the planning process of the central business district (CBD) in Chinese cities. However, Underground Space plans in most of the Chinese CBDs have yielded few results because they are rarely realized in practice as envisioned. The roots of the problem can be traced back to the lack of effective planning approaches and, more importantly, the administrative management for planning implementation. In a broader sense, this also mirrors deeper deficiencies in the planning and administrative system for urban Underground Space in China. In this context, Shanghai Hongqiao CBD offers an exemplary case for other Chinese cities with respect to Underground Space planning and implementation in CBDs or other key areas. This paper presents in detail the entire process of Underground Space development in terms of planning and the implementation dimensions in the Core Area Phase I in Shanghai Hongqiao CBD, which is also applicable to other Chinese cities.

mainstreaming sustainable development into a city s master plan a case of urban Underground Space use
Land Use Policy, 2009Co-Authors: Nikolai BobylevAbstract:Abstract The paper offers an analysis of Urban Underground Space (UUS) use and its influence on cities’ sustainability. It has been widely recognized that urban land is a valuable resource. During recent decades UUS, especially in big cities, has become a scarce and valuable resource. This paper outlines UUS use, including some quantitative descriptors and an analysis of its historical evolution. Historic top-down development of Urban Underground Infrastructure (UUI) and shortcomings in its planning have resulted in a lack of available UUS for new developments. A sectoral approach to UUS development and UUS availability on a first-come-first-served basis does not allow the full benefits that UUI can provide for urban sustainability. This paper recognizes UUS as a valuable non-renewable resource, which requires careful consideration during city planning. It focuses on the need and opportunities for mainstreaming UUS into cities’ Master plans. To facilitate this, UUS services are listed and classified; their characteristics are identified and discussed. UUS users are also identified and possible conflicts between them are discussed. State-of-the-art consideration of UUS in cities’ Master plans is critically analyzed and suggestions are made for mainstreaming UUS and sustainability issues into Master plans. It is recommended that the following are implemented: three-dimensional planning; prioritizing UUS services; studying prospective functional and spatial interrelations between different types of infrastructures; and integrated assessment.
