The aim of traffic flow design in commercial building space planning is to create a comfortable, easily accessible, and identifiable spatial structure in a complex and changeable business environment. However, modern commercial building spaces often appear to be inconsistent with the usage requirements after they are put into use. To understand the real experience evaluation of users, this study selects the commercial project “Guangzhou Nanpu Times Commercial Building Space” as its subject. Based on post-occupancy evaluation (POE), this study uses the analytic hierarchy process (AHP) to construct an evaluation index system of commercial building space traffic flow. The weights and satisfaction scores of the indexes are calculated through expert interviews and questionnaires to analyze the evaluation and reasons for the commercial building space traffic flow design after using the facilities. We thereby obtain the design points of commercial building space traffic flow to provide a scientific, reasonable, and practical basis for the subsequent design of the same type of traffic flow to drive the prosperity and development of commerce.
Street commerce is the basic unit of urban structure and an important part of people’s life. With the continuous advancement of online commerce, people’s consumption habits and consumption patterns have begun to change. (1) Background: During the epidemic, the global business environment changed dramatically, and traditional street business has also been hit hard, leaving a lot of idle space. The question is how to solve the problem of activating the commercial street space after its decay, and realize its sustainable development. (2) Methods: This paper takes the commercial space of Nonglin Street as the object, constructs the relevant factors affecting the commercial space of the street by using the theory of scenes, and collects the data by means of a field investigation and questionnaire. According to a weight analysis and satisfaction analysis, the advantages and disadvantages of the commerce in Nonglin Street are understood. (3) Results: The importance of the three variables of the appearance, comfort and diversity of the commercial space in Nonglin Street is very high and the satisfaction is low. (4) Conclusions: Nonglin Street need to increase diversified forms of business, open block space, integrate regional cultural symbols, and improve the management model of street commerce.
Urban renewal is extensively practiced around the world and has attracted substantial attention among scholars and the public. To ensure that urban renewal is directed toward sustainable development goals, sustainability assessments for urban renewal projects have become critical topics. Simultaneously, the ex ante evaluation research of urban renewal projects has not received enough academic attention, and most results have not fully considered the localization of criteria and the internal correlation between criteria/dimensions. Therefore, this paper proposes an ex ante decision model for the sustainability assessment of urban renewal projects based on a hybrid multiple-attribute decision-making (MADM) approach, which includes 3 dimensions and 16 criteria. It uses a case in Guangzhou to assess the sustainable potential of the project and explore relevant improvement strategies. Empirical results from the Decision Testing and Evaluation Laboratory (DEMATEL) indicate that the economic (D1) and environment (D2) dimensions both impact the social and cultural (D3) dimensions, with the environment (D2) dimension being impacted by the economic (D1) dimension. The criteria occupying the “cause” position include reducing construction costs and materials expenses (C5), increasing greening configuration and open space (C6), reducing resource consumption and waste (C8), improving existing land-use efficiency (C2), promoting the biodiversity of space (C9), and strengthening the safety of pedestrians and residents (C15), where increasing greening configurations and open space (C6) and reducing resource consumption and waste (C5) are considered the key criteria based on the results of DEMATEL and the DEMATEL-Analytic Network Process (DANP). The modified VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method revealed that the economic (D1) dimension has poor performance, and its improvement needs to be prioritized. Further improvement strategies are proposed based on the influence network relationship graph (INRM). In conclusion, our results show that urban community renewal projects in Guangzhou are steadily progressing toward a sustainable vision.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
