Sustainable development of the transportation system in the Tan Son Nhat international airport area

Abstract

The study focuses on comprehensively analyzing the current state of traffic organization in the area surrounding Tan Son Nhat International Airport—one of the most critical traffic pressure points in Ho Chi Minh City. Survey results and data collection indicate severe congestion on gateway roads during peak hours. The increasing volume of vehicles entering and exiting the airport has led to prolonged traffic jams, negatively impacting service quality and the efficiency of the area's transportation infrastructure.Based on the assessment of current conditions and urban development trends, the study proposes a set of sustainable development solutions through 2030 with a vision to 2050. Three main pillars are identified: (1) upgrading road infrastructure by widening main corridors and constructing overpasses and underpasses at major intersections; (2) expanding the public transportation network by developing metro lines with direct airport connections, and improving existing bus services; (3) enhancing inter-regional connectivity with Long Thanh International Airport.Using a traffic demand forecasting model, two scenarios are simulated: maintaining the status quo and implementing a coordinated set of interventions. The analysis shows that the proposed scenario significantly improves traffic capacity, reduces delays, increases public transport usage, and enhances the overall sustainability of the urban transportation network.
