Factors influencing the effectiveness of urban underground transportation construction investment activities during the construction phase in Hanoi

Abstract

Amidst a burgeoning population density and a rising influx of individual vehicles, Hanoi is confronted with pressing issues including severe traffic congestion, encroachments onto sidewalks and roadways for parking, and heightened levels of air pollution. The development of an underground transportation system in the urban core is essential, contributing to the resolution of current issues and optimizing urban land utilization. Hanoi is currently investing in the construction of road tunnels, pedestrian tunnels, underground parking lots, and subway lines. Nevertheless, the construction process is progressing slowly and encountering various challenges, particularly during the implementation phase. This article examines the factors affecting the effectiveness of urban underground construction projects during the construction phase in Hanoi, utilizing Cronbach's Alpha analysis, Exploratory Factor Analysis (EFA), and Multivariate Regression Analysis. The results indicate four influencing factor groups: objective factors, project deployment capability, construction capacity, and coordination between contractors and relevant units. These analytical findings serve as a basis for proposing solutions to enhance the efficiency of urban underground construction projects during the construction phase in Hanoi.
