Exploring the Nonlinear and Heterogeneous Effects of Accessibility on Intercity Passenger Transport Carbon Emissions

Abstract

Abstract Reducing carbon emissions while ensuring travel efficiency is a major challenge in sustainable transportation planning. Accessibility plays a key role in achieving both goals, yet its impact on carbon emissions remains unclear. This study ... Practical Applications Understanding the spatially differentiated effects of accessibility on carbon emissions is crucial for developing low-carbon intercity transportation strategies. This study examines the nonlinear and spatially heterogeneous impacts ...
