EDITORIAL: Moving Towards a Sustainable Transportation System: Focus Issue on Sustainable Transportation Technology and Policy

摘要

In a world with extensive and rapid urbanization and changing climate, transportation systems present major challenges and as well provide great opportunities for enhancing and promoting urban sustainability. Transportation decisions and practices have considerable direct and/or indirect impacts on urban society, economy, and environment, both positive and negative, for example through changes in travel time and economic productivity, urban connectivity, emissions and attendant air quality concerns, traffic accidents, and noise pollution as well as water quality issue, heat island effects, and climate change. Sustainable transportation technology and policy are urgently needed to mitigate the negative environmental impacts from transportation and promote the green economy through smart growth.
