The Impact of Shared Mobility Modes on Urban Transportation Structure: A Case Study of Megacities

Abstract

Megacities face challenges like traffic congestion and environmental pollution, with traditional transportation systems struggling to
cope. Shared mobility modes, such as bike-sharing and ride-hailing, offer flexible and sustainable travel options, particularly in Chinese cities. This paper, drawing on shared economy and sustainable transportation theories, analyzes the impact of shared mobility on traffic congestion, environmental outcomes, and private vehicle use in cities like Shanghai, New York, and London. The study finds that shared mobility
can reduce traffic pressure and emissions, but its long-term success depends on policy support and integration with public transportation.
