Critical Success Factors of Underground Logistics Systems from the Project Life Cycle Perspective

The surging demand for logistics systems brought about by the vigorous development of e-commerce makes urban traffic more and more congested. The need for a sustainable transition in terms of urban transportation infrastructure also encourages the further innovation of logistics systems. The urban underground logistics system (ULS) emerges as a promising alternative for realizing efficient large-scale freight distribution in megacities. However, there are relatively few studies that have explored the factors that determine the uptake of ULSs in practice. This paper thus aims to identify the critical success factors of ULSs throughout project life cycle stages. Firstly, a desktop study and a study using the Delphi method were conducted to extract the critical success factors (CSFs) of ULS projects. Secondly, a questionnaire survey was conducted to collect data on the perceived significance of the selected success factors from ULS professionals. Thirdly, the intergroup comparison of the significance of CSFs and exploratory factory analysis were used to ascertain the critical factors and latent determinants influencing the development of ULS projects. In total, 36 CSFs in the four life cycle stages of ULS projects were finalized. The identified factors represent the seven latent determinants in developing a ULS project, namely, overall feasibility and acceptance of the ULS, prototype system, and business model, competence and resources for ULS construction and operation, station layout and intermodal transportation, government policies and incentives, long-term planning of the underground space and logistics network, and market investigation and forecasting. The research findings of the paper help guide practitioners and policy makers on decisions made during ULS planning and construction and provide a reference performance evaluation framework for ULS projects.

Automated summary

This study aims to identify the critical success factors of urban underground logistics systems (ULS) throughout project life cycle stages. Through desk research, Delphi method, and questionnaire survey, a total of 36 critical success factors were identified. These factors cover various aspects of ULS projects, including overall feasibility and acceptance, prototype system and business model, competence and resources for construction and operation, station layout and intermodal transportation, government policies and incentives, long-term planning of underground space and logistics network, as well as market investigation and forecasting. The research findings provide guidance for practitioners and decision-makers in ULS planning and construction, and serve as a reference for performance evaluation of ULS projects.
