“…In addition, with the development of artificial intelligence, algorithms such as the Harmony Search Algorithm (HAS), Artificial Bee Colony Algorithm (ABC), and Self-Organizing Map (SOM) have been applied in geological hazard risk or geological quality assessment. They have the potential to improve the valuation models [150][151][152]. In the future, computer technology can be introduced on this basis to address the limitations of the existing evaluation models.…”

The contradiction between urban construction and sustainable development has led to an increasing demand for urban underground space (UUS). The value evaluation of urban underground space (UUSVE) is of great significance in promoting the rational development of UUS. Currently, no study has reviewed the literature on UUSVE. This paper provides a preliminary review of the legal basis and element composition of UUS, and the themes, evaluation objects, and evaluation methods of UUSVE, attempting to clarify the current status of UUSVE and analyze its future development trends. Finally, by summarizing the legal basis, element composition, research status and trends of UUSVE, three suggestions to strengthen UUSVE are proposed: (1) to strengthen the research on the shortcomings of UUSVE methods; (2) to build an evaluation index library and case library; and (3) to emphasize interdisciplinary collaboration, with a particular focus on the application research of machine learning.

“…Economic considerations including population density, GDP per capita and ground price were considered in the suitability evaluation of underground space development in Wuhan [24]. The weights assigned to these assessment indicators are predominantly determined using the subjective analytic hierarchy process (AHP) using expert opinion [25][26][27], the objective entropy weight method (EWM) using the degree of dispersion of data in the indicators [18,28,29], and the combined weights method that considers subjectivity and objectivity [30], etc. Furthermore, the multiobjective linear weighting method [25], fuzzy comprehensive evaluation method [31], and multi-level grey evaluation method [32] are mainly utilized as the mathematical models for UUSR assessment.…”

With the rapid advancement of urbanization, the development and utilization of urban underground space resource (UUSR) has become one of the dominant features. However, in certain areas, the development of UUSR may cause disasters and accidents, such as ground collapse, settlements, and tunnel water gushing. Geological environmental factors (GEFs) are recognized as the fundamental constraining factor of UUSR development. In this paper, quality based on GEFs is defined to assess the development difficulty degree of UUSR. A 3D assessment framework is proposed based on 3D geological modelling and the interval continuous mathematical model (ICMM). The subjective and objective joint weight method of analytic hierarchy process and entropy weight method (AHP–EWM) is utilized to determine the weight of each indicator. The quality index (QI) of each spatial node of the 3D geological model is calculated by the ICMM mathematical model. A case study conducted in the Jiangbei New District of Nanjing, China, serves as a demonstration of the UUSR assessment. The results clearly illustrate the 3D distribution characteristics of the quality in the study area, offering valuable insights for future 3D urban underground space planning.

Formulation of the problem. Solving the problems of urban transport communications, in particular the constantly growing intensity of automobile traffic in megalopolises, is one of the main directions of minimizing the environmental and man-made risks of the urban environment. Global concepts of greening large cities pay considerable attention to the possibilities of underground space to take on the functions of the most dangerous and risky surface objects and communications, since the impact of any underground object on the environment is much lower (than similar on the surface) and can be better controlled. At the same time, planning for the development of underground transport infrastructure should be based on a systematic methodology and tools for analyzing complex systems. Purpose. It consists in the use of system tools (BOCR method - criteria of benefits, opportunities, costs and risks) for planning underground transport infrastructure of large cities to ensure minimization of environmental and man-made risks of urban space and prioritization for the construction of road tunnels (for example, the General Plan of the Kiev city). Methodology. A methodology and decision support toolkit for calculating the priorities of alternatives based on hierarchical and network criteria models are proposed. The modified BOCR method developed by the authors (N. Pankratova, N.I. Nedashkovskaya) was applied to assess decision alternatives taking into account benefits, costs, opportunities and risks. Results. System models of two road tunnels, according to the General plan of the Kiev city until 2025 were developed. Assessment of the models using the BOCR method (criteria for benefits, opportunities, costs and risks) was performed. The priorities of alternatives for tunnels' routes aggregated over a network of parameters and a reasonably expedient sequence of their construction were calculated according to the criteria for reducing the environmental and man-made risks of the urbanized space. Scientific novelty. For the first time, the target function of the system model for the development of underground infrastructure in large cities is to minimize the environmental and man-made risks of urban space. The capabilities of the modified BOCR method have been expanded and two alternative tunnel track models have been successfully tested. Practical significance. The research methods and results provide investors, city state administrations and public organizations with an effective toolkit for assessing the priority of the construction of underground urban facilities to regulate urban development in order to improve environmental standards and the safety of life in megacities.
