Roads, economy, population density, and CO 2: A city-scaled causality analysis

摘要

Highlights?Causalities among road, economy, population density and CO2emissions are explored through Granger test.?Roads development will not cause GDP growth, but cause increment in CO2emissions and population density.?The compactness and high population density generate less per capita CO2emissions.?Promoting new energy vehicles, green transport infrastructures, and environmentally friendly transport modes.?Accelerating new town development through the support of road construction.AbstractThe exploration of the nexus among transport infrastructure, economy, population, and environment would be important for sustainable transport system planning. In this paper, we choose Shanghai as a case, account its transport
