Transportation Infrastructure: High-Speed Trains and Sustainable Mobility in Lagos Metropolis

Abstract

The Lagos Metropolis in Nigeria is one of the most populous and fastest-growing urban areas in the world, with a population estimated around 21 million. The city’s transportation infrastructure faces significant challenges, leading to traffic congestion, air pollution, and limited access to sustainable mobility options. The study examined the impact of high-speed trains and sustainable urban mobility on the city’s transportation landscape. The study employed the interpretivism philosophy and a qualitative approach in data collection and analysis. Primary data were generated mainly through key informant interviews. Findings revealed that high-speed rail can improve connectivity, reduce travel times, and lower carbon emissions. The study concludes that the Lagos metropolis could significantly improve accessibility, reduce traffic congestion, and promote environmental sustainability, ultimately enhancing the quality of life for the city’s residents. The study recommends substantial capital investment in initiatives like BRT, light rail, cycling infrastructure, and pedestrian-friendly design
