Potential and observed accessibilities of terminal logistics facilities:A case study of express delivery outlets in the central urban area of Guangzhou City
The rapid development of e-commerce and express delivery industries has promoted urban logistics activities from production to the daily life.At the same time,the spatial accessibility of terminal logistics facilities is becoming a research hotspot.Due to the lack of data,however,existing research mostly focuses on potential accessibility and lacks effective characterization of revealed or observed accessibility,which restricts a comprehensive understanding of the accessibility of terminal logistics facilities.This study took the central urban area of Guangzhou City as an example,and measured the potential accessibility and observed accessibility of express delivery network facilities based on the two-step floating catchment area method using the express delivery network directory and its delivery data.The results showed that:1)Peripheral areas such as Baiyun District and Huangpu District have higher potential accessibility,but urban centers such as Liwan District,Haizhu District,and Yuexiu District have higher observed accessibility.2)Potential accessibility of peripheral areas is overestimated,while the urban centers'accessibility is underestimated.3)The correlation results show that improving the accessibility of express delivery outlets may be crucial to the prosperity and development of the urban socioeconomic system.The research results provide a new understanding of the accessibility characteristics of terminal logistics facilities and provide a basis for policymakers and relevant stakeholders on how to optimize the spatial layout of facilities.
